Agilent 71910A Data Sheet

100 Hz to 26.5 GHz
The Agilent Technologies 71910A/P 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 stimulus­response applications.
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.

Agilent 71910A/P Search Receiver Specifications
Specifications describe the instrument’s warranted performance over the 0°C to +55°C temperature range after per­forming a front-panel “CAL ALL.” Characteristics provide information about non-warranted instrument performance. Nominal values indicate the expected value of the parameter. All specifications apply after the instrument’s temperature has been stabilized for one-hour, self-calibrated routines have been run, and the preselector peak function has been executed. Where specifications are subject to minimization with error correction routines, corrected limits are given. Values given on pages 2, 4, and 5 are specifications, except where noted.
The 71910A/P wide bandwidth receiver has two modes of operation: search and collection. In the search mode, the receiver sweeps across user-specified frequency spans with IF bandwidths of 3 MHz and below, reporting signal ampli­tudes to the display and GPIB port. A signal may be investigated using the collection mode, in which the receiver is fixed-tuned with IF bandwidths from 10 to 100 MHz. IF and demodulated outputs are available from the 70911A IF module. Search specifications refer to displayed and reported signals. Collection specifications and characteristics refer to the 321.4 MHz IF and Video outputs of the 70911A IF module.
