Dynamic Accuracy at Compression – Low Freq

This topic page applies to the E5071C using the Factory Recommended or Normal Variant test plan.

This test measures the dynamic accuracy at compression power level for the receivers.

For the E5071C with frequency options 8.5 GHz and below, the test process measures two power deltas, one at the top of the receiver input power range, and another at an expected linear part of the input power range.

For the E5071C with frequency options greater than 8.5 GHz, the function generator power is measured using the power meter, then the test process measures four power deltas, one at the top of the receiver input power range, and three in the middle of the input power  range.

A negative test result indicates compression while a positive result indicates expansion. There will be a note in the report stating:

A Fail result in this test implies that Dynamic Accuracy specification cannot be guaranteed in the Compression range of the receiver.

Source unlevelled messages may appear on the ENA screen during this test, and the test may time out and abort. This does not necessarily indicate a problem with the operation of the test. The work-around is to add a 3 dB pad.

  1. The DSG (Device Substitution Group) is listed below the equipment description, if applicable. These devices are required to be mapped in TME to execute a test. DSGs require either GPIB communication or are important for dynamic measurement uncertainty calculations. N/A refers to required equipment that is not mapped as DSGs in TME.
  2. Refer to the main Required Test Equipment for a list of alternative models.
  3. Two required for 2-port ENAs; four required for 4-port ENAs.
