30.Ordering Information

To order a part listed in the replaceable parts table, include the Hewlett-Packard part number (with the check digit) and the quantity required. Address your order to the nearest Hewlett-Packard office. The check digit will ensure accurate and timely processing of your order. To order a part that is not listed in the replaceable parts table, include the instrument model number, instrument serial number, description and function of the part, and the quantity of parts required. Address the order to the nearest Hewlett -Packard office.

31.Manual Changes

These paragraphs contain manual change instructions for backdating this manual for HP Model 1793A Microwave Converters with the serial number prefix 2407A.

Instruments with Serial Prefix 2407A have System I1 cabinet parts and hardware that are English thread. Instruments with Serial Prefix 2520A and higher have System I1 cabinet parts and hardware that are METRIC thread.

In Table 7 . Replaceable P U Y ~ Sboth, English and Metric thread part numbers are listed for the System I1 cabinet parts. These correct part numbers are referenced under the instrument’s serial number prefix.

Instruments with the serial number prefix 2407A have MP3 (rear frame), MP8 (rear panel), and associated english thread hardware, that are screwed together. These parts have been changed to a riveted, one piece assembly that is referenced to MP8. To replace MP8 you must order the Rear Panel Assembly 11793-20009, and the metric screws for the side struts and rear feet.

33.Principles of Operation Simplified Block Diagram

A simplified block diagram of the Microwave Converter is shown in Figure 10. The signal at the RF INPUT connector is routed through an input switch either to the Direct Path (and out the IF OUTPUT connector), or to the Down-Convert Path. The Down-Convert Path has a 3 dB RF Attenuator (to improve input SWR), a Mixer (tte down-converter), an IF Low-pass Filter (to remove the sum component of the mixing process while passing the difference component), and a +1S dB IF Amplifier (to restore signal loss through the Down-Convert Path).

Usually, the LO frequency selected is higher than the frequency of the input signal. (The measuring instrument assumes this.) The difference frequency (the IF) is filtered by the IF Low-Pass Filter, which has a 3 dB corner of 800 MHz. The IF should be kept between the range of 10 and 700 MHz.

If the instrument has the optional LO Amplifier installed, the measuring instrument automatically switches in the amplifier whenever an LO frequency greater than 18 GHz is selected.
