Trigger Source
Selects the source of the trigger event. Some of the trigger sources require additional
options.
●
Free Run (Fast Sync):
The measurement starts immediately after it is initiated. The R&S CMW decodes
the signal to derive its slot and frame timing. This procedure is repeated after each
measurement cycle.
This value is not suitable for list mode measurements.
●
Free Run (No Sync) :
The measurement starts immediately after it is initiated, without any synchroniza-
tion. This trigger mode can only be used for power monitor, ACLR and emission
mask measurements.
●
IF Power:
The measurement is triggered by the power of the received signal, converted into
an IF signal. The trigger event coincides with the rising or falling edge of the detec-
ted LTE burst.
●
…External…:
External trigger signal fed in via TRIG A or TRIG B on the rear panel of the instru-
ment.
