5.Description
The HP Model 11793A Microwave Converter
1.3to 26.5 GHz. For frequencies below 1.3 GHz, signals are routed directly to the input of the measuring instrument. Instruments suitable for lower frequency measuring are the HP 8901B Modulation Analyzer or the HP 8902A Measuring Receiver.
For input signals above 1.3 GHz, the Microwave Converter routes the signal through an internal mixer which mixes the input signal with an external local oscillator. The difference frequency (that is, the intermediate frequency or IF) is filtered, amplified, and then appears at the IF OUTPUT connector. The IF should be between 10 and 700 MHz.
The Microwave Converter requires a +8 dBm leveled output from the LO. For LOs with insufficient power above 18 GHz, an optional internal amplifier (1 8 GHz to 26.5 GHz) is available. The measuring instrument controls switching of the RF path and of the LO amplifier via a
