Performance Test
6. NOISE FLOOR
6. NOISE FLOOR
Description
This test checks the noise floor for all the receiver ports of the ENA. The noise
floor is tested by performing load-ended absolute measurements with the test
ports terminated with "Load" devices, 16 times with segment sweep points for
specified frequency ranges. The measurement data is calculated from the RMS
deviation value from the 16 measurement data for each sweep frequency point.
Test equipment
Test Equipment (DSG)

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.
