Fig. 4-4: Trigger settings
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 to derive its slot and frame timing. This procedure is repeated after each mea-
surement cycle.
●
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 detected
TD-SCDMA burst.
●
…External…:
External trigger signal fed in via TRIG A or TRIG B on the rear panel of the instrument.
Remote command:
Trigger Slope
Qualifies whether the trigger event is generated at the rising or at the falling edge of the
trigger pulse. This setting has no influence on "Free Run" measurements and for evalu-
ation of trigger pulses provided by other firmware applications.
