Programming a Channel Mode Change
Programming a Channel Mode Change
This section provides an example of how to change a mobile station’s channel mode to enhanced full rate
speech via GPIB while a call is connected and a measurement is running.
The following procedure assumes that an active link is established between the test set and the mobile station.
See
“Establishing an Active Link with the Mobile Station” on page 28
.
1. Ensure the mobile is initially in full rate speech channel mode.
2. Configure the parameters for the measurement(s) you want to run using the SETup subsystem.
3. Start the measurement(s) using the INITiate subsystem.
4. Change the mobile’s channel mode to enhanced full rate speech.
5. Use the INITiate:DONE? command to find out if the measurement results are available.
6. Use the FETCh? command to obtain the measurement results.
Program Example
The following program uses the TX Power measurement to show how to change the channel mode to enhanced
full rate speech while a measurement is running. The TX Power measurement is chosen because it is one of
the measurements that is supported in enhanced full rate speech mode.
10 OUTPUT 714;”CALL:TCHANNEL:CMODE FRSPEECH” !Ensure mobile is in
20 !full rate speech channel mode initially.
30 OUTPUT 714;”SETUP:TXPOWER:CONTINUOUS OFF” !Configures trigger
40 !mode to single for a TX Power measurement.
50 OUTPUT 714;”SETUP:TXPOWER:COUNT:NUMBER 100” !Configures a
60 !multi measurement of 100.
70 OUTPUT 714;”SETUP:TXPOWER:TRIGGER:SOURCE AUTO” !Configures the
80 !trigger source to auto.
90 OUTPUT 714;”INITIATE:TXPOWER” !Start TX Power measurement.
100 OUTPUT 714;”CALL:TCHANNEL:CMODE EFRSPEECH” !Sets the channel
110 !mode to enhanced full rate speech while
120 !the TX Power measurement is running.
130 REPEAT
140 OUTPUT 714;”INITIATE:DONE?” !Check to see if TX Power
150 !measurement is complete.
160 ENTER 714;Meas_complete$
170 UNTIL Meas_complete$=”TXP”
180 OUTPUT 714;”FETCH:TXPOWER:ALL?” !Fetch TX Power results.
190 ENTER 714;Integrity,Avg_tx_pwr
200 PRINT “TX Power Measurement Results”
210 PRINT “Integrity=”;Integrity
220 PRINT “TX Power=”;Avg_tx_pwr
230 END
