Agilent
RF Preselector, 20 Hz to 2 GHz
For the 8566B or 8568B Spectrum Analyzer
Data Sheet
Your High-Performance
Spectrum Analyzer can also
be a Test Receiver
Add the 85685A RF preselector to the
8566B or 8568B general-purpose spec-
trum analyzer, and you have a test receiv-
er for specialized applications. The RF
preselector enhances these high-perfor-
mance 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 over-
load protection from out-of-band signals.
The result, for tests in the presence of
high-level interference, is a measure-
ment range 30 dB greater than that of the
spectrum analyzer alone. (The improve-
ment is even greater in the presence of
broadband pulse-interference.)
The test receiver is easy to operate; sim-
ply 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 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.)
The 85685A preselector adds:
Automatic filter tracking
Input overload protection
Low system noise
to the 8566B and 8568B spectrum analyzers.
