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 performance 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:
•S
21
and S
12
• broadband power
•S
11
and S
22
•S
11
and S
22
(with a 50 Ω or 75 Ω load, instead of the cable)
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 85032B/E (50 Ω) or HP 85036B/E (75 Ω).
