The 85685A preselector adds:
Add the 85685A RF preselector to the 8566B 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 20 Hz to 2 GHz 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 binput-filter tracking, and the spectrum analyzer reports preselector operating conditions on the CRT display. For remote operation with a computer, the receiver system is fully GPIB programmable (GPIB is hardware, software, documentation, and support for IEEE-488 and IEC-625, worldwide standards for interfacing instruments.)
