2.5.6 UL Logging Tests
The UL logging measurement provided by the WCDMA signaling application is pro-
grammed as follows:
●
The application is controlled by SCPI commands with the following syn-
tax:
...:WCDMa:SIGN:ULLogging:...
●
After a
*RST
, the measurement is switched off. Use
READ:WCDMa:SIGN:ULLogging:...?
to initiate a single-shot measurement and
retrieve the results. You can also start the measurement using
INIT:WCDMa:SIGN:ULLogging
and retrieve the results using
FETCh:WCDMa:SIGN:ULLogging:...?
.
The examples in this section focus on commands directly related to the UL logging
measurement. For general configuration of the signaling application refer to
ter 2.5.1, "Signaling Application"
