Power Meter Accuracy Test - Agilent Technologies E8362B Service Manual

PNA Series Microwave Network Analyzers
E8362B, E8363B, E8364B

Power Meter Accuracy Test

This test is intended for power meters used in testing the PNA series network analyzers.
The "Dynamic Accuracy Test"
a higher accuracy than the standard power meter.
Power meters with options G12 and H12 specify an improved instrumentation accuracy
over a limited power range. (These power meters do not contain unique hardware.) A
power meter may be returned to the factory to have one of these options added to an
existing power meter or to renew the calibration for one of these options.
This test procedure is an alternative to returning the power meter to the factory. When a
power meter passes this test, it is considered to be calibrated for the G12 or H12 option
even though it has not been returned to the factory.
This test procedure is available on the Internet as a separate document, Agilent Part
Number E8356-90051. The on-line document may have a more recent print date. Refer to
