(Power Suite, WCDMA)
Rel Limit (PSD)
Enters a relative limit value for the level of the power spectral density. This sets the
amplitude levels to test against for any custom offsets. The amplitude level is
relative to the power spectral density. If multiple offsets are available, the list
contains 6 entries. The offset closest to the carrier channel is the first one in the list.
[:SENSe]:ACP:OFFSet[n][:OUTer]:LIST:TEST selects the type of testing to be
done at each offset.
You can turn off (not use) specific offsets with [:SENSe]:ACP:OFFSet[n]
[:OUTer]:LIST:STATe.
The query returns the 6 sets of real numbers that are the current amplitude test
limits, relative to the power spectral density, for each offset.
Offset[n] n = 1 is base station and n = 2 is mobiles. The default is base station (1).

Notes Some Modes do not support Offset subopcode 2. In those cases, commands with subopcode 2 are
accepted without error but ignored
Preset When "Max Num of Offsets" on page 1010 is 12, the preset value of Offset G ~ L is the same as the
Offset F value
