Lab Quality You Can Get a Handle On
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.
