HP 70911A Ultra-Wide Bandwidth IF Module![]()
|
Options are available to provide 70 MHz or 140 MHz IF outputs, demodulated FM out, or analog I/Q demodulated outputs. Also available are channel filters for the 70 MHz IF to selected any required bandwidth and shape. (A maximum of 15 filters can be configured.)
The HP 70911 IF section is intended to work with the HP 71209A Option 001 spectrum analyzer to form the HP 71910A receiver. Aside from this combination, there is no specified performance. The following specifications indicate performance which is realized when configured into the HP 71910A receiver.
