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.
