4.2.15 Trigger Signals
The CDMA2000 signaling application provides trigger signals that can be used by
other R&S
CMW applications to synchronize to the generated CDMA2000 forward sig-
nal. This is especially useful to trigger CDMA2000 TX measurements (option
R&S CMW-KM800).
The available trigger signals are described below.
To address the trigger signals in remote commands, use the following strings, with <i>
replaced by the instance number of the signaling application:
●
"CDMA2000 Sig<i>: Event"
●
"CDMA2000 Sig<i>: Paging Frame (20.00 ms)"
●
"CDMA2000 Sig<i>: Power Control Frame (1.25 ms)"
●
"CDMA2000 Sig<i>: PP2S (2.00 s)"
●
"CDMA2000 Sig<i>: Super Frame (80.00 ms)"
●
"CDMA2000 Sig<i>: Sync Frame (26.67 ms)"
Event Trigger
The signaling application is able to raise events that other application could use as trig-
ger signals. Currently this mechanism is used for OLTR measurements (option CMW
KM-800) in combined signal path mode, where the event triggers mark the start of an
OLTR evaluation interval.
Paging Channel Frame Trigger
Trigger event at the beginning of each paging channel frame (20.00 ms).
Power Control Group Trigger
Trigger event at the beginning of each Power Control Group on the Forward Traffic
Channel (1.25 ms).
Periodic Pulse Trigger
Periodic trigger event raised every 2 seconds.
Sync Channel Superframe Trigger
Trigger event at the beginning of each Sync Channel Superframe (80 ms).
Sync Channel Frame Trigger
Trigger event at the beginning of each Sync Channel Frame (26.67 ms).
