Dynamic Accuracy Test

This test applies to the following models:

Port 1 is always tested. Port 2 is only tested if Option 211 is installed.

The Dynamic Accuracy test measures the relative amplitude linearity of a receiver. The measurement compares power steps (a change from one power level to another) measured by the DUT receiver to the same power steps measured by the R-channel receiver of the PNA-X.

Test type:

functional

Related specification:

none (Dynamic Accuracy is a factor in Corrected Measurement Uncertainty.)

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.

Connection Setups

The following notes apply to illustrations in the FieldFox Help:

  • Only a single representative model will be shown.
  • Some illustrations may differ than those in TME.

  • For procedures that apply to multiple ports, illustrations will show the setup on only one test port.
