4.4.4 RX Measurement: Speech
The audio connection requires the audio measurements application; see
The RX measurement speech provided by the CDMA2000 signaling application is pro-
grammed as follows:
●
The application is controlled by SCPI commands with the following syn-
tax:
...:CDMA:SIGN:...
and the token
...:SPEech...
.
●
You can start the speech measurement by establishing the speech connection with
the DUT and retrieve the measurement results using
SENSe:CDMA:SIGN<i>:RXQuality:SPEech:...
commands.
The examples in this section focus on commands directly related to the speech mea-
surement. For general configuration of the signaling application refer to chapter
ter 4.4.1, "General Configuration"
