Receiver Compression - Low Frequency (Up To 8.5 Ghz Option); Description; Test Equipment - Keysight E5071C ENA Service Manual

Performance Test

1. RECEIVER COMPRESSION - Low Frequency (Up to 8.5 GHz option)

1. RECEIVER COMPRESSION - Low Frequency (Up to 8.5 GHz option)

Description

This test measures the compression at the specified maximum power level for
the receivers. This compression test is only for options
230/235/430/435/240/245/440/445/260/265/460/465/280/285/480/485 at
low frequencies. 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. The difference between the deltas represents the
compression at the top of the 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.

1. The DSG (Device Substitution Group) is listed below the equipment descrip-
tion, 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.
