"Lower Tone at DUT Out" (
LTO
), "Lower Tone at DUT In" (
LTI
), "Upper Tone at DUT
Out" (
UTO
), and "Upper Tone at DUT In" (
UTI
) are measurements of the two funda-
mental waves of the intermodulation measurement.

Gain Compression Tab
Allows you to configure and perform compression point over frequency measurements.
This softtool is available and has the same appearance for both frequency- and non
frequency-converting DUTs.
The compression point over frequency works by performing a power sweep for each
frequency point of a linear frequency grid. Given the configured
the compression point is calculated for each of these power sweeps.
The power sweep is stopped, when the compression point at the current frequency is
reached. However, the maximum number of measurement points is
, which can easily become a large number.
As a result, the compression point traces "
Compression Point Power In/Compression
over frequency" can be shown.
