Receiver Compression — Low Freq

This topic page applies to the E5072A using the Factory Recommended or Normal Variant test plan.

This test measures the compression at the specified maximum power level for the receivers.

This 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.

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.
