Notes
Comma separated list of values.
OFFSet1 is for BTS, 2 for MS. Default is BTS.
You must be in the mode that includes SEM measurement to use this command. Use
:INSTrument:SELect to set the mode.
Couplings Coupled to Start Freq. When the stop freq goes below the start freq, the start freq is automatically
adjusted to the stop freq minus 100 Hz.
If the current mode is DVB-T/H, this value will be modified automatically according to the limit type
and the output power of the transmitter which is less or more than 25 W.
If the current mode is ISDB-T, this value will be modified automatically according to the limit type.
Preset For modes (except MSR, LTEAFDD, LTEATDD and WLAN) without option N9060A–7FP, the preset
value is as follows.
SA: 2.715 MHz, 3.515 MHz, 4.00 MHz, 8.00 MHz, 12.50 MHz, 15.0 MHz
WCDMA:2.715 MHz, 3.515 MHz, 4.000 MHz, 8.000 MHz, 12.50 MHz, 15.0 MHz|3.485 MHz,

1xEVDO: 780.0 kHz, 1.98 MHz, 4.0 MHz, 4.0 MHz, 12 MHz, 12 MHz|1.98 MHz, 4.0 MHz, 4.0 MHz,
4.0 MHz, 4.0 MHz, 4.0 MHz
When option N9060A–7FP is installed in these modes, the preset value of Offset G ~ L is the same
as the Offset F value.
