7 How to use the front panel Make sure the unit is turned on. From the Sy stem key group Press Local to activate the front panel k eypad if the unit is not already in local m ode. (If the Local Lockout com mand is in effect, cycle power to return the unit to local m ode.
8 The following chart shows the com mands in the Voltage function m enu. Some comm ands may not appear on all models. Menus are circular, you can return to the starting position by continuously pressing p or q .
9 Some basic operations Make sure the unit is turned on. Use either the front panel k eys or the corresponding SCPI comm ands. The column on the left indicates the front panel k eys that program the indicated action. If the SCPI program ming sy ntax is substantially different from the front panel m enu comm and, it is shown inside parentheses ( ).
10 Set the rms current limit (and peak current on A gilent 6811B/6812B/6813B units) CURR:LEV 10 When this comm and is sent, the rms current lim it is set to 10 A. If m ore current than the program med lim it is drawn, the output voltage am plitude is reduced to keep the rm s current within the specified limit.
11 Measuring the output All m easurements are based on acquiring and subsequently processing output waveform information. When the ac source is on, it takes m easurements and updates the front panel m eter continuously. The Meter k ey accesses the measurem ent functions from the front panel.
12 Harmonic measurements Use the harm onic menu to mak e harmonic m easurements of the output current. The following exam ple illustrates the current mag nitude measurem ents returned at harmonics 0 to 5. Note that harm onic 1 is the fundamental. Harm onic 0 is the dc component.
13 Programming output transients Up to now the ac source has been program med with the transient system in Fixed mode. The following examples briefly describe the transient system’ s Step, Pulse, and List modes, w hich require the application of a trigg er to implem ent the transient mode.
14 More transient examples The previous exam ples showed how the transient system can be used to control the output voltage amplitude. The transient sy stem can also control output frequency, phase, w aveform shape, v oltage and frequency slew rates, offset v oltage, and peak current lim it.
15 Programming trigger sy nchronization and delays The previous transient exam ples were programm ed to respond to imm ediate triggers. Howev er, delayed and phase synchroniz ed triggers can also be program med as show n in the following examples.
16 Trigger delay ; 90 degree phase synchronization VOLT: M STEP VOLT 120 VOLT:T 150 DELAY .0167 SYNC:SOUR PHAS SYNC:PHAS 90 INIT : IMM ED When these comm ands are sent, the voltag e amplitude changes at the next 90 degree phase ang le that occurs after the .
