The 492 is a high performance, rugged, state-ofthe-
art instrument of compact size, with microprocessor
logic control. Full programmability via
GPIB (IEEE Standard 488-1978) compatibility is
available in the 492P version.
Three-knob operation provides use as simple as
1, 2, 3 through microprocessor coupled functions
such as resolution bandwidth, video bandwidth,
sweep time, frequency span, RF attenuation, and
reference level. Measurement accuracy is enhanced
through the use of A dB mode, which
switches in 0.25 dB steps.
Digital storage and processing facilitate trace
comparisons and add measurement capability
through the Max Hold function for frequency drift
and amplitude change measurements. Arithmetic
operations can be performed between traces or
between a trace and a reference. Digital noise
averaging mode results in trace smoothing. With
digital storage, the display is steady and without
flicker, even at the lowest sweep speeds; plus
trace values may be retained as long as power is
492P Makes Spectrum Analysis
Automatic, and Easy.
Two instruments in one, the 492P is a fully
programmable version of the 492 Spectrum Analyzer.
It incorporates all of the 492's lab quality
performance and ease of use features when
used as a manual instrument. Push the "Reset to
Local" button and the 492P becomes a 492—with
operation from the front panel. But, most important,
the 492P opens the way to automated
spectrum analysis and documentation via its IEEE
Standard-488 (GPIB) interface. This versatility
makes the 492P useful in many applications in the
lab, factory or field.
Programmability/GPIB features can be added to
492 Spectrum Analyzers, serial number B030000
and above. This means if you want to postpone a
programmability/GPIB decision because of budget
constraints, or for any other reason, you can
convert your 490 Series spectrum analyzer later.

Service Manual Volume 1

The Service manual consists of two volumes that contain
information necessary to test, adjust, and service the Porta-
ble RackmountlBenchtop 4961496P Spectrum Analyzer .
The intent is to provide as complete information as possible
as an aid in servicing this instrument . The Table of Oantents
at the beginning of Volume 1 lists contents of each section
contained within Volume 1 .
Change information that involves manual corrections
andlor additions pending manual reprint and bind, is located
at the back of the Service manual in the CHANGE INFOR-
MATION section.
History knformation with the updated data is integrated
into the text or diagrams when a page or diagram is updat-
ed . Original pages are identified by the symbol @,revised
pages by a revision date in the lower inside corner of the
page . The manual may contain revision :; that do not apply
to your instrument ; however, history information with updat-
ed data, is integrated into the text or diagram when the
page or diagram is revised.
The person using these instructions should be knowl-
edgeable in digital and analog circuit theory . Circuit analysis
is primarily functional . The intent is to provide
sufficient in-
formation for the technician to isolate the majority of mal-
functions to a block of circuitry. Those users with an
understanding of logic and analog circuitry should then be
able to further isolate the malfunction to a specific compy-
nent or components .
