Agilent Technologies, Inc. 85685A RF Preselector, 20Hz to 2GHz, Spectrum Analyzer
Feature:
Minimum Frequency: 20Hz
Maximum Frequency: 2GHz
Measurements With A General-Purpose Spectrum Analyzer
Add the HP 85685A RF Preselector to the HP 8565B or 8568B general-purpose spectrum analyzer, and you have a test receiver for specialized applications. The RF Preselector enhances these high-performance spectrum analyzers with tracking filters and preamplifiers that cover the 20Hz to 2GHz range. The spectrum analyzer / test receiver is sensitive to low-level signals while providing overload protection from out-of-band signals. The result, for tests in the presence of high-level interference, is a measurement range 30 dB greater than that of the spectrum analyzer alone. (The improvement is even greater in the presence of broadband pulse-interference.)
The test receiver is easy to operate; simply use the spectrum analyzer controls without concern for preselector settings. The preselector automatically adjusts input-filter tracking, and the spectrum analyzer reports preselector operating conditions on the CRT di
