N5290/1A Millimeter-wave Test System Operator’s Check
Performing the N5290/1 A System Operator's Check
The N5290/1 A System Operator's Check is done to verify the system to isolate
the problem instrument or after the N5292A test set has been repaired and the
N5292A test Operator's Check has been completed. Refer to “N5292A
Functional Verification Procedure” on page 3-16 .
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 tested:
— attenuation ranges of all installed attenuators
— calibration of the receivers
— frequency response of the receivers
— phase lock and leveling
— basic functional test of noise floor and trace noise
Accessories Used in the Operator's Check
For more, refer to “Required Service Test Equipment” on page 2-3 .
