23. On the synthesizer, press [FLTNESS ON/OFF) (amber LED on). The power produced at the point where the power meter/sensor was disconnected is now calibrated at the frequencies and power level specified above.
Using Detector Detector calibration is useful for characterizing and compensating for Calibration negative diode detectors used in external leveling. Detectors may be characterized by three operating regions as shown in Figure 1-12: the square law, the linear, and the transition region.
If an HP-IB error message is displayed verify that the interface connections are correct. Check the HP-IB address of the power meter and ensure that it is the same address the synthesizer is using (address 13 is assumed). Refer to the menu map 8, System, for the key sequence necessary to reach softkey Meter A&s .
Using the Tracking Feature Peaking Peaking is the function that aligns the output filter (YTM) so that its passband is centered on the RF output, in CW or manual-sweep mode. Use peaking to obtain the maximum available power and spectral purity, and best pulse envelopes, at any given frequency above 2.
ALC Bandwidth Selection The ALC bandwidth defaults at factory preset to the auto selection ALC Bandwidth Select Auto which selects the appropriate bandwidth (high or low) for each application. To make the bandwidth selection, the synthesizer determines which functions are activated and uses the decision tree shown in Figure l-23.

Programming Getting Started Programming HP-IB, the Hewlett-Packard Interface Bus, is the instrument-to- instrument communication system between the synthesizer and up to 14 other instruments. Any instrument having HP-IB capability can be interfaced to the synthesizer, including non-HP instruments that have “GPIB,” “IEEE-488,” “ ANSI MC1.
HP-IB General Information Interconnecting Cables Instrument Addresses HP-IB Instrument Nomenclature Programming the Synthesizer 1-56 Getting Started Programming Figure C-2 shows the synthesizer rear-panel HP-IB connector and suitable cables, and describes the procedures and limitations for interconnecting instruments.
In the programming explanations that follow, specific examples are included that are written in a generic dialect of the BASIC language. BASIC was selected because the majority of HP-IB computers have BASIC language capability. However, other languages can also be used.
Remote Remote causes an instrument to change from local control to remote control. In remote control, the front panel keys are disabled (except for the (LOCAL] key and the POWER switch), and the amber REMOTE annunciator is lighted. The syntax is: where the device selector is the address of the instrument appended to the HP-IB port number.
Local Local is the complement to REMOTE, causing an instrument to return to local control with a fully enabled front panel. The syntax is: Some BASIC examples: 10 LOCAL 7 which effects all instruments in the network, or 10 LOCAL 719 for an addressed instrument (address 19).
to clear an addressed instrument. Related statements used by some computers: RESET CONTROL SEND The preceding statements are primarily management commands that do not incorporate programming codes. The following two statements do incorporate programming codes, and are used for data communication.
CONVERT IMAGE IOBUFFER TRANSFER Enter Enter is the complement of OUTPUT, and is used to transfer data from the addressed instrument to the controller. The syntax is: ENTER is always used in conjunction with OUTPUT, such as: 100 OUTPUT 719; ” . . . programming codes .
(line feed) is received. However, the LF bit pattern could coincidentally occur randomly in a long string of binary data, where it might cause a false termination. Also, the bit patterns for the ASCII CR (carriage return), comma, or semicolon might cause a false termination.
Getting Started with This section of Chapter 1 describes the use of the Standard SCPI Commands for Programmable Instruments language (SCPI). This section explains how to use SCPI commands in general. The instrument command summary (at the end of this chapter) lists the specific commands available in your instrument.
Standard Notation This section uses several forms of notation that have specific meaning. Command Mnemonics Many commands have both a long and a short form, and you must use either one or the other (SCPI does not accept a combination of the two). Consider the FREQuency command, for example.
Commands and Responses,” discusses message terminators in more detail. Response Examples Response examples look like this: 1.23 These are the characters you would read from an instrument after sending a query command.
Essentials for Beginners This subsection discusses elementary concepts critical to first-time users of SCPI. Read and understand this subsection before going on to another. This subsection includes the following topics: Program and Response Messages These paragraphs introduce the basic types of messages sent between instruments and controllers.
.
root level 1 BB cc DD c +I rtl level 2 EE FF GG HH Figure l-25. A Simplified Command Tree JJ In the command tree shown in Figure l-25, the command closest to the top is the root command, or simply the root. Notice that you must follow a particular path to reach lower level subcommands.
n Semicolon A semicolon separates two commands in the same message without changing the current path. w Whitespace White space characters, such as <tab> and <space>, are generally ignored. There are two important exceptions. White space inside a keyword, such as :FREq uency, is not allowed.
- BB cc DD l-h rtl EE FF GG HH JJ QQ R D 0 R Sets current path to ROOT :AA:BB:EE;FF;GG 0 N NO change to current path 0 D Set current path DOWN one level 4) vmv :AA:BB:EE; :AA:DD:JJ Figure l-26. Proper Use of the Colon and Semicolon In Figure l-26, notice how proper use of the semicolon can save typing.
Subsystem Command These paragraphs introduce a more complete, compact way of Tables documenting subsystems using a tabular format. The command table contains more information than just the command hierarchy shown in a graphical tree. In particular, these tables list command parameters for each command and response data formats for queries.
the matching command. The parameter type is listed adjacent to each named parameter. More About Commands Query and Event Commands. Because you can query any value that you can set, the query form of each command is not shown explicitly in the command tables.
The command is correct and will not cause errors. It is equivalent to sending: “FREquency : CW 5 GHZ ; : FREUuency :MULTiplier 2”. Example 2: “FREquency 5 GHZ; MULTiplier 2” This command results in a command error. The command makes use of the default [:CW] node.
-7.89E-01 use either E or e in exponentials +256 leading + allowed .5 digits left of decimal point optional Examples of numeric parameters in commands: 100 OUTPUT @Source ; ” : FREquency : STARt l.OE+09” 1 IO OUTPUT @Source ; I’ : LIST:FREquency lO.
Although discrete parameters values look like command keywords, do not confuse the two. In particular, be sure to use colons and spaces properly. Use a colon to separate command mnemonics from each other. Use a space to separate parameters from command mnemonics.
Example Programs The following is an example program using SCPI compatible instruments. The example is written in HP BASIC. This example is a stimulus and response application. It uses a source and counter to test a voltage controlled oscillator. Example Program Description.
210 OUTPUT OStimulus;"*IDN?" 220 ENTER OStimulus;Id$ 230 PRINT Id$ 240 PRINT 250 ! 260 PRINT "Counter Used II . . . 270 OUTPUT OResponse;"*IDN?" 280 ENTER QResponse;Id$ 290 PR.
a 1 in the source Output Queue. The program waits at line 410 until the 1 returned by *OPC? is entered. Note that following each OUTPUT containing a query is an ENTER to retrieve the queried value. If you do not use paired OUTPUT S and ENTER S , you can overwrite data in the instrument Output Queue and generate instrument errors.
Details of Commands and Responses In This Subsection This subsection describes the syntax of SCPI commands and responses. It provides many examples of the data types used for command parameters and response data.
a semicolon. You must always end a program message with one of the three program message terminators shown in Figure l-29. Use <new line>, C-END>, or <new line> <-END> as the program message terminator. The word <-END>> means that EOI is asserted on the HP-IB interface at the same time the preceding data byte is sent.
NOTE: SP = white space, ASCII characters 0 ,. to 9 ,. and 11 ,. to 32 ,. Figure 1-31. Simplified Common Command Syntax As with subsystem commands, use a <space> to separate a command mnemonic from subsequent parameters. Separate adjacent parameters with a comma.
SCPI Data Types Table 1-3. SCPI Data Types Parameter Types Response Data Types Numeric c Real or Integer Extended Numeric Integer Discrete Discrete Boolean Numeric Boolean String Definite Length Block.
rounds the parameter. For example, if an instrument has a programmable output impedance of 50 or 75 ohms, you specified 76.1 for output impedance, the value is rounded to 75. If the instrument setting can only assume integer values, it automatically rounds the value to an integer.
Discrete Parameters. Use discrete parameters to program settings that have a finite number of values. Discrete parameters use mnemonics to represent each valid setting. They have a long and a short form, just like command mnemonics. You can used mixed upper and lower case letters for discrete parameters.
Integer Response Data. Integer response data are decimal representations of integer values including optional signs. Most status register related queries return integer response data. Examples of integer response data: 0 signs are optional +lOO leading + sign allowed -100 leading sign allowed 256 never any decimal point Discrete Response Data.
Programming Typical Measurements In This Subsection This subsection illustrates how the general SCPI concepts presented in previous subsections apply to programming real measurements. To introduce you to programming with SCPI, we must list the commands for the synthesizer.
Use of the Command Tables In Table 1-4, notice that a new column titled “Allowed Values” has been added to the command table. This column lists the specific values or range of values allowed for each parameter. A vertical bar (I) separates values in a list from which you must choose one value.

Programming the Status System In This Subsection This subsection discusses the structure of the status system used in SCPI instruments, and explains how to program status registers. An important feature of SCPI instruments is that they all implement status registers the same way.
There may or may not be a command to read a particular condition register. Transition Filter The transition filter specifies which types of bit state changes in the condition register will set corresponding bits in the event register. Transition filter bits may be set for positive transitions (PTR), negative transitions (NTR), or both.

l ABORt Causes the sweep in progress to abort and reset. If INIT: CONT is ON it immediately restarts the sweep. The pending operation flag (driving *OPC, *WAI, and *OPC?) undergoes a transition once the sweep is reset.
SCPI COMMAND SUMMARY If this is ON, each time a frequency or power is changed, CALibration:AM[:EXECutel is attempted. l CALibration:AM[:EXECutel When AM is on and the synthesizer is in the CW or manual mode, the synthesizer performs a modulator calibration as long as power sweep is not active.
DIODe PMETer MMHead Initiates a calibration of the external flatness. Depends on value of CALibrat ion: PMETer : RANGe. Initiates a calibration of the power meter flatness. Depends on value of CALibrat ion : PMETer : RANGe. Initiates a calibration of the source module flatness.
Sets and queries an array of up to 801 frequency-correction pairs. This correction information is used to create a correction array that can be added to the internal calibration array. The correction entered is at the associated frequency. Frequencies in between frequency-correction pair values are determined by linear interpolation.
l DIAGnostics:INSTrument:PRINter:ADDRess <num> l DIAGnostics:INSTrument:PRINter:ADDRess? Sets the HP-IB address of the printer to use during some of the calibration procedures when the synthesizer assumes HP-IB control. *RST and power on do not effect this command.
HP 8360 User’s Handbook <manual entry point> a string response that identifies the paragraph number in the HP 8360 Assembly-Level Repair Manual to begin the troubleshooting procedure. l DIAGnostics:TEST:CONTinue Causes the selftest execution to continue when paused for raw data examination.
l DIAGnostics:TEST:LOG[:STATe]? l DIAGnostics:TEST:LOG[:STATe] ON|OFF|l|O Selects and queries the raw data logging ON/OFF switch. Both commands are executable in selftest mode. After *RST, the setting is 0. l DIAGnostics:TEST:LOOP ON|OFF|l|O l DIAGnostics:TEST:LOOP? Selects and queries the test looping ON/OFF switch.
SCPI COMMAND SUMMARY positions to the bandwidth, < 20 Hz and > 100 kHz, but any numeric is accepted. The value is compared to 1 kHz and the correct position is determined (> 1 kHz sets the position to 100 kHz and 5 1 kHz sets the position to 20 Hz).
SCPI COMMAND SUMMARY The synthesizer use s “bumping” to move unspecified frequency parameters, but if the final value of any of the frequency headers is the result of bumping, then an error is generated since the user is not getting what was specified.
Sets and queries the manual frequency. This controls the output frequency in swept manual mode. The limits are START and STOP. *RST value is the same as FREQ : CENTER. See FREQ : CENTER for more information. l FREQuency:MODE FIXediCWlSWEeplLIST l FREQuency:MODE? Sets and queries the switch that selects either swept, CW or list operation.

SCPI COMMAND SUMMARY before changing to the next frequency. After *RST, the value is 100 PUS ( MIN ). l LIST:DWELl:POINts? [MAXimumlMINimum] Returns the number of dwells entered using the LIST:DWELl command.
*RST state is AUTO. l LIST[:POWer]:CORRection (<num>[DB]IMAXimumlMINimum~l*801 l LISTC:POWer]:CORRection? Sets and queries the list of correction levels that correspond to each of the frequencies entered using the LIST:FREQ command. The attenuator is not allowed to change during the list execution.
SCPI COMMAND SUMMARY MARKer[n]:MODE How the frequency of the marker is determined. FREQuency Absolute frequency is used. The limits are confined to the present START and STOP frequency limits. DELTa The value is specified with respect to the reference marker.
l MODulat ion : STATe? Queries the status of any modulation. If any of the modulation states are on, then it returns a 1, otherwise it returns a 0. Power Subsystem Any place where dBm is accepted as a suffix, any level suffix is accepted also. In the absence of a suffix, the units are assumed to be as set by the UNIT :POW command.
Programming a specific value for POWer : AMPLif ier : STATE sets POWer:AMPLifier:STATE:AUTOto OFF. l POWer:AMPLifier:STATE:AUTO ONlOFFlOll l POWer:AMPLifier:STATE:AUTO? Sets and queries the automatic selection of the doubler amplifier state. Programming a specific value for POWer : AMPLif ier : STATE sets POWer:AMPLifier:STATE:AUTO to OFF.
SCPI COMMAND SUMMARY the sweep mode then the output level is controlled by the start, stop, center and span functions. If in the fixed power mode then the output is controlled by the POW C: LEVEL1 command.
SCPI COMMAND SUMMARY FREQ:MODE Affect on Slope CW or LIST Rotates around 0 Hz. SWEep or Rotates around the start frequency. STEP The *RST value is 0. l POWer:SLOPe:STATe ON|OFF|l|O l POWer:SLOPe:STATe? Sets and queries the power slope state. *RST value is 0.
SCPI COMMAND SUMMARY analogous to those for frequency sweep. Power sweep is allowed to be negative, unlike frequency sweeps. “RST value is 0 dBm. l PULM:EXTernal:DELay <num>[time suffix] IMAXi.
SCPI COMMAND SUMMARY Pulse Subsystem Since frequency and period are inversely related, if both are sent in the same message, only the last one is applied. If the WIDth command and either the FREQuency or PERiod command are sent in the same message, they must be accepted without error if the resulting pulse is possible.
command to set the switch will cause ROSC:SOUR:AUTO OFF to be done also. The *RST value is automatically determined. l ROSCillator:SOURce:AUTO ONlOFFlllO a ROSCillator:SOURce:AUTO? Sets and queries the automatic reference selection switch. The *RST value is 1.
l STATus:QUEStionable[:EVENt]? Queries the Data Questionable Event Register. This is a destructive read. l STATus:QUEStionable:NTRansition <num> l STATus:QUJZStionable:NTRansition? Sets and queries the Negative TRansition Filter for the Data Questionable Status Register.
l SWEep:DWELl <num>[time suffix] lMAXimumlMINimum l SWEep:DWELl? CMAXimumIMINimum] Sets and queries the amount of time in seconds that the synthesizer stays (dwell) at each step after reporting a source settled SRQ and pulsing the Trigger Out line low.
HP 8360 User’s Handbook SCPI COMMAND SUMMARY l SWEep:MANual:POINt <num>lMAXimumlMINimum l SWEep:MANual:POINt? [MAXimumlMINimum] Sets and queries the step point number to go to and lock. The value is a unitless value that is limited between 1 and the number of points requested.
If you change step size then the number of points will be changed to span/step and a Parameter Bumped execution error is reported. If span or points are changed then STEP= SPAN/POINTS.
SCPI COMMAND SUMMARY HP 8360 User’s Handbook Sets and queries the save/recall register number to alternate the foreground state of the instrument. The *RST value is 1. l SYSTem:ALTernate:STATe ONlOFFlllO l SYSTem:ALTernate:STATe? Sets and queries the state of the Alternate State function.

Converting HP The following paragraphs are intended to assist you in converting 6340141 Systems to existing HP 8340/8341 based systems to HP 8360 series synthesized HP 8360 Series sweeper based systems. Both manual and remote operational Systems differences are addressed.
Manual Operation Compatibility The HP 8360 series synthesized sweepers are designed to be, in all but very few cases, a complete feature superset of the HP 8340/8341 synthesized sweepers.
System Connections The HP 8510 Network Analyzer The HP 8360 series synthesizer is compatible with any HP 8510 network analyzer with firmware revision 4.0 or higher. To upgrade firmware for an existing HP 8510, an HP 11575C Revision 4.0 Upgrade Kit or an HP 11575D Revision 5.
The HP 8757C/E Scalar Network Analyzer The connections between the analyzer and the HP 8360 series are similar to the connections between the analyzer and the HP 8340/8341. The HP 8360 series differs from the HP 8340/8341 in one connection only. It unnecessary to connect the modulator drive signal from the analyzer to the source.
Remote Operation Language Compatibility The HP 8360 series synthesized sweepers support three HP-IB programming languages; network analyzer language, SCPI (Standard Commands for Programmable Instruments), and M.
. Features not available in one of the language modes is marked by a horizontal line in the corresponding column. In the interest of brevity all SCPI commands have been listed in their most concise form. For a complete and comprehensive listing of the synthesizer SCPI commands refer to “SCPI Command Summary,” in Chapter 2.

OPERATOR’S CHECK and ROUTINE MAINTENANCE WARNING No operator serviceable parts inside. Refer servicing to qualified personnel. To prevent electrical shock, do not remove covers. Operator’s Checks The local operator’s check (front panel use) allows the operator to make a quick check of the main synthesizer functions prior to use.
Local Operator’s Check Description The preliminary check provides assurance that most of the internal functions of the synthesizer are working. The main check provides a general check of the overall functions of the synthesizer. No external equipment is needed.
Main Check 1. 2. 3. 4. 5. 6. 7. 8. 9. Press [SERVICE). Select Selftest CFull) . Check that all tests performed pass. Press [PRESET). If the display indicates a user preset was performed, select Factory Preset . Verify that the green SWEEP LED is blinking, the amber RF ON/OFF LED is on, and the red INSTR CHECK LED is off.
Routine Maintenance Routine maintenance consists of replacing a defective line fuse, cleaning the air filter, cleaning the cabinet, and cleaning the display.
How to Clean the Fan The cooling fan located on the rear panel has a thin foam filter. How Filter often the filter must be cleaned depends on the environment in which the synthesizer operates. As the filter collects dust, the fan speed increases to maintain airflow (as the fan speed increases, so does the fan noise).
How to Clean the Clean the cabinet using a damp cloth only. Cabinet How to Clean the The display of the synthesizer is protected by a plastic display filter. Display Filter To clean the display filter, use mild soap or detergent and water, or a commercial window cleaner (ammonia does not hurt the plastic surface).
5 Instrument History How to Use Instrument History This manual documents the current production versions of the “standalone” HP 8360 series synthesized sweepers which include the HP 83620A/22A, HP 83623A/24A, HP 83640A/42A, and HP 83630A/50A.
