HP 871X and HP 8714C
RF Network Analyzers
The HP 8712C and HP 8714C are easy-to-use RF network analyzers optimized
for production measurements ,of 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 dBm output power.
The three-channel, dual mode receivers provide dynamic range of greater
than 100 dB 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 hardkeys and softkey
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 dB and
source match to 30 dB for unproved measurements.

How to Use This Guide
The first 7 chapters of this guide explain how to perform measurements,
calibrate the instrument, and use the most common instrument functions.
Chapters 8 through 12 are reference material. Use these chapters to look
up information such as front panel features, specific key functions and
specifications.

Step 1. Check the Shipment
After you have unpacked your instrument, it is recommended that you keep
the packaging materials so they may be used if your instrument should need
to be returned for maintenance or repair.
Check the items received against the Product Checklist (included in your
shipment) to make sure that you received everything.
Inspect the analyzer and all accessories for any signs of damage that may
have occurred during shipment. If your analyzer or any accessories appear
to be damaged or missing, call your nearest Hewlett-Packard Sales or Service
office. Refer to ‘fable 10-l in Chapter 10 for the nearest office.
