HP and HP
RF Network Analyzers
The HP and HP are easy-to-use RF network analyzers optimized
for production measurements reflection and transmission parameters. The
instrument integrates an RF synthesized source, transmission/reflection test
set, multi-mode receivers, and display in one compact box.
The source features 1 Hz resolution, 50 ms (or faster) sweep time, and up
to + 16
output power.
The three-channel, dual mode receivers provide dynamic range of greater
than 100
in narrowband measurement mode. For measurements of
frequency-translating devices, the network analyzer features broadband
internal and external detector inputs. The receivers incorporate digital signal
processing and microprocessor control to speed operation and measurement
throughput.
Two independent measurement channels and a large CRT display the
measured results of one or two receiver channels in several user-selectable
formats. An external VGA monitor can be connected to the rear panel for
enhanced measurement viewing in color.
Measurement functions are selected with front panel and
menus. Measurements can be printed or plotted directly with a compatible
peripheral. Instrument states can be saved to the internal floppy disk,
internal non-volatile memory, or internal volatile memory. Built-in service
diagnostics are available to simplify troubleshooting procedures.
Measurement calibrations and data averaging provide performance
improvement and flexibility. Measurement calibrations consist of normalizing
data, utilizing the internal factory calibration, or calibrating with external
standards. Measurement calibration reduces errors associated with directivity,
frequency response, and source match. Directivity is corrected to 40
and
source match to 30 for unproved measurements.
