The 71910A is a receiver for monitoring signals from 100 Hz to 26.5 GHz. It provides a cost-effective combination of search and wide-bandwidth collection capabilities for surveillance and signal monitoring applications. Its flexibility makes it an ideal downconverter in stimulous-response applications. To search for signals, it sweeps over user-specified spans up to 26.5 GHz wide using bandwidths up to 3 MHz. Wide dynamic range ensures signals of various amplitudes are quickly identified. Once a signal is located, the receiver is fixed-tuned and the wide IF bandwidths are used for signal collection. (Bandwidths up to 36 MHz are available with microwave preselection, and up to 100 MHz unpreselected.) A linear IF signal path provides good signal fidelity with standard outputs of 321.4 MHz IF and linear video. Optional outputs include 70 and 140 MHz IF, analog I/Q, and demodulated FM. Options permit customization to the configuration that best meets the application requirements. This can include adding a preamplifier, deleting the display (as shown on the right in the picture), or other modifications.
