Power Meter Accuracy Test
Power Meter Accuracy Test
This test is intended for power meters used in testing the E5071C. The “Dynamic Accuracy
Test” requires the use of a power meter that has been calibrated to a higher accuracy than
the standard power meter.
Power meters with options G12 and H12 specify an improved instrument 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.
Power Meters That Can Be Tested Using This Procedure
This procedure assume that the E4419B power meter is being tested.
NOTE
It is recommended that the revision number for the power meter “Main Firmware” be
Ax.03.00 or higher.

Description of the Test
The power meter accuracy is verified for various power inputs and the actual readings are
recorded in a test record. A range calibrator is used to provide the reference inputs.
