RF Network Analyzers Performing the Operator's Check
Service Guide 1-3
Performing the Operator's Check
The operator's check should be performed when you receive your instrument, and any time
you wish to have confidence that the analyzer is working properly. The operator's check
does not verify conformance to specifications, but should give you a high degree of
confidence that the instrument is performing properly if it passes.
The operator's check consists of making the following measurements with the cable that
was supplied with your analyzer:
Equipment List
To perform the operator's check, you will need the following:
• A known good cable such as the one that was supplied with your analyzer. The cable you
use should have ≤0.5 dB of insertion loss up to 1.3 GHz, and ≤0.75 dB of insertion loss
from 1.3 to 3.0 GHz.
• A known good load (>40 dB return loss) that matches the test port impedance of your
analyzer such as one from calibration kit HP/Agilent 85032B/E (50Ω) or HP/Agilent
85036B/E (75Ω).
NOTE The illustrations depicting the analyzer’s display in this section were made
using an 8714ET. Other models’ displays will have minor differences in
annotation.
