The frequency offsets and enabling of the measurement at these offsets can be
defined per carrier. For more details see 3GPP2 C.S0033-D, section 4.5., "Limitations
on Emission".
Remote command:
3.3.7 Trigger Settings
The "Trigger" parameters configure the trigger system for both TX measurements: the
1xEV-DO multi evaluation and OLTR measurement.

Trigger Source
Selects the source of the trigger event. Some of the trigger sources require additional
options.
●
Free Run:
The measurement starts immediately after it is initiated. The R&S
CMW decodes
the signal and derives its slot timing. This procedure is repeated after each mea-
surement cycle.
●
IF Power
The measurement is triggered by the power of received signal, converted to an IF
signal. The trigger event coincides with the rising or falling edge of the detected
1xEV-DO power step. This setting can be used to measure short signal bursts
when no continuous 1xEV-DO signal is available (see
