Version 4 27 Feb 08 INTRODUCTION The OSCOR Microwave Downconverter option (MDC-2100) expands the OSCOR ’s frequency range limit to 21GHz. The MDC-900 extends the OSCOR ’ s range to 9GHz . Note: General descriptions of the MDC-2100 in this guide may not always include exceptions for the MDC-900, which does not cover the 9 to 21GHz spans.

Version 4 27 Feb 08 Inst alling the MDC-2100/MDC-900 In order to use the MDC with the OSCOR, a special connector (the OEP-2100) must be installed in the connector tray of the OSCOR. This connect or should be installed permanently into the connector tray and provides for easy connection of the MDC while not affecting the OSCOR normal operation.
Version 4 27 Feb 08 Operational Control of the MDC-2100/MDC-900 OSCOR Version 4.0 Operational control of the MDC-2100 is provided by the OSCOR keypad using the normal OSCOR functional control. For example, in the OSCOR SWEEP or ANALYZE modes, pressing the F1 button will toggle through all of the OSCOR inputs including the MDC- 2100 frequency bands.
Version 4 27 Feb 08 o You can choose to begin with MDCB-all if you wish. You must view both MDCA- all and MDCB-all to see the entire spectrum. • Set the span to 1.5GHz, if necessary. If a smaller span init ially displays, press SWEEP/ANALYZE (CONTROL area) to select SWEEP .

Version 4 27 Feb 08 includes the desired frequency span. The table below provides some examples and recommended search span for speed and accuracy. Example of a Desired Frequency Span: Recommended Implementation: 4 – 6GHz 3 – 9GHz (MDCA-1 & MDCB-1/OSCOR 5.
Version 4 27 Feb 08 Microwave T r ansmission Considerations for the MDC There are important principles and considerations to understand when dealing with microwave frequency radiators. • As the frequency increases, the penetration of RF signals through buildin g materials, foliage, etc.
Version 4 27 Feb 08 it is absolutely necessary in order to save time. A good rule of thumb is to assume that the MDC has an antenna pattern that is about 100 degrees wide. In other words, it is necessary to point the MDC in at least 4 different directions around the room to cover the perimeter.
Version 4 27 Feb 08 Using the MTU-2100 Microwave T est Unit The MTU-2100 is designed to provide a simple test to verify that the MDC is working properly. When the button is pressed on the MTU, low power signals are generated at about 5.9, 11.8, and 17.

Version 4 27 Feb 08 REI MDC-2100/MDC-900 16 Technical Bulletin 24 April 2002 For the MDC-900 and MDC-2100 This bulletin describes a calibration process to ensure the maximum technical performance for the MDC unit.
An important point after buying a device REI MDC-900 (or even before the purchase) is to read its user manual. We should do this for several simple reasons:
If you have not bought REI MDC-900 yet, this is a good time to familiarize yourself with the basic data on the product. First of all view first pages of the manual, you can find above. You should find there the most important technical data REI MDC-900 - thus you can check whether the hardware meets your expectations. When delving into next pages of the user manual, REI MDC-900 you will learn all the available features of the product, as well as information on its operation. The information that you get REI MDC-900 will certainly help you make a decision on the purchase.
If you already are a holder of REI MDC-900, but have not read the manual yet, you should do it for the reasons described above. You will learn then if you properly used the available features, and whether you have not made any mistakes, which can shorten the lifetime REI MDC-900.
However, one of the most important roles played by the user manual is to help in solving problems with REI MDC-900. Almost always you will find there Troubleshooting, which are the most frequently occurring failures and malfunctions of the device REI MDC-900 along with tips on how to solve them. Even if you fail to solve the problem, the manual will show you a further procedure – contact to the customer service center or the nearest service center
