<Threshold>
Defines the trigger threshold for power trigger sources.
Parameters:
<Threshold>
Range:
-47 dB to 0 dB
*RST:
-26 dB
Default unit: dB (full scale, i.e. relative to reference level minus
external attenuation)
Example:
See
Configuring the Trigger System
Firmware/Software:
V2.1.20
Manual operation:
See
TRIGger:WCDMa:MEAS<i>:TPC:DELay
<Delay>
Defines a time delaying the start of the measurement relative to the trigger event. This
is useful if the trigger event and the uplink DPCH slot border are not synchronous. A
measurement starts always at an uplink DPCH slot border. Triggering a measurement
at another time may yield a synchronization error.
For internal trigger sources aligned to the downlink DPCH an additional delay of 1024
chips is automatically applied. It corresponds to the assumed delay between downlink
and uplink slot.
This setting has no influence on "Free Run" measurements.
Parameters:
<Delay>
Range:
-666.7E-6 s to 0.24 s
*RST:
0 s
Default unit: s
Example:

Manual operation:

TRIGger:WCDMa:MEAS<i>:TPC:TOUT
<TimeOut>
Selects the maximum time that the R&S
CMW will wait for a trigger event before it
stops the measurement in remote control mode or indicates a trigger timeout in manual
operation mode. This setting has no influence on "Free Run" measurements.
