Absolute Amplitude Accuracy Test

This test applies to the following models:

The absolute amplitude accuracy is the deviation of the FieldFox's power reading from that of a known input power. This test verifies the FieldFox absolute amplitude accuracy versus input level at 50 MHz.

Required Test Equipment

The network analyzer used in this test must be calibrated prior to running the test. The calibration will need to be repeated once every three days or if the connectors or cables have been disturbed. If it's been within the three day time frame and the connectors and cables have not been disturbed, then the network analyzer calibration is not necessary and you may proceed with the test.

For a list of required equipment and calibration instructions to perform the network analyzer calibration, go to the Network Analyzer Calibration Procedure topic page.
