2.5.2 BER Tests
The BER measurement provided by the WCDMA signaling application is programmed
as follows:
●
The application is controlled by SCPI commands with the following syn-
tax:
...:WCDMa:SIGN:BER:...
●
After a
*RST
, the measurement is switched off. Use
READ:WCDMa:SIGN:BER?
to
initiate a single-shot measurement and retrieve the results. You can also start the
measurement using
INIT:WCDMa:SIGN:BER
and retrieve the results using
FETCh:WCDMa:SIGN:BER?
.
The examples in this section focus on commands directly related to the BER measure-
ment. For general configuration of the signaling application refer to
2.5.2.1
