HP 70911A Ultra-Wide Bandwidth IF Module

The HP 70911A ultra-wide bandwidth IF module adds receiver functionality to certain HP 70000 series spectrum analyzers. Designed specifically to work with the HP 71209A option 001 analyzer, it adds receive bandwidths of 10 MHz to 100 MHz in 10% increments. When the HP 70911A is added to the HP 71209A option 001, the combination constitutes the HP 71910A wide-bandwidth surveillance receiver.

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.)

[ Features ]

Resolution bandwidths from 10 MHz to 100 MHz
IF Gain from 0 dB to 70 dB in 1 dB steps
Video output at full selected bandwidth
Optional 70 or 140 MHz IF output
Channel filters available for the 70 MHz output
Optional demodulated FM output
Optional analog demodulated I/Q outputs

[ Specifications ]

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.
