Tests, Adjustments, and Troubleshooting
Preliminary Checks

Preliminary Checks

Preliminary checks include the following:

—

The Operator’s Check

The Operator’s Check tests the basic functionality of the source, switches,

and receivers in the network analyzer.
The performance of the network analyzer is specified in two ways: system

specifications and instrument specifications. It is the end user’s

responsibility to determine which set of specifications is applicable to their

use of the network analyzer. This section includes system verification. If

instrument specifications verification is required, contact Keysight. Refer to

https://www.keysight.com/find/usb-vna

A network analyzer measurement “system” includes the network analyzer,

calibration kit, test cables, and any necessary adapters. The system

verification software is used to verify the system’s conformance to the

“system” specifications. A “pass” result demonstrates that the network

analyzer test cables and adapters perform correctly as a system. It DOES

NOT demonstrate that any one component performs according to its

individual specifications. A change to any part of this measurement system

requires a re-verification of the system.

The Operator’s Check

The Operator’s Check is a software driven test that checks the basic operation

of the assemblies in all of the measurement port signal paths. By performing

the Operator’s Check, the following are determined:

— attenuation ranges of all internal attenuators
— calibration of the receivers
— frequency response of the receivers
— phase  lock
— noise  floor  and  trace  noise
— various  voltages  throughout the network analyzer

Allow the network analyzer to warm up for at least 15 minutes before

performing the Operator’s Check.
