Performance Test
2. RECEIVER COMPRESSION - Low Frequency (Over 8.5 GHz Options)
2. RECEIVER COMPRESSION - Low Frequency (Over 8.5 GHz Options)
Description
This test measures the compression at the specified maximum power level for
the receivers. This test is only for 2D5/4D5/2K5/4K5 options in low
frequencies. First 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.
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 amplitude "expansion." If this test fails, there will be a note in
the report stating that the dynamic accuracy result is not valid.
Test equipment
Test Equipment (DSG)
1
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 measure-
ment uncertainty calculations. N/A refers to required equipment that is not
mapped as DSGs in TME.
