Chapter 4, Description of Fields

Fields

Reading The Received Data Fields To read the decoded data messages received from the mobile station on the reverse control channel or reverse voice channel or the raw data message bits displayed when a decoding error occurs, the control program queries one, some, or all of the six received data fields. The information in each field is returned exactly as displayed on the CRT. The information is returned to the control program as a quoted string (“This is an example.”).

The received data fields are read only data fields.

The :RCDD1? through :RCDD6? query commands are used to read the contents of the six received data fields.

Syntax

:RCDD<1-6>?

Example

OUTPUT 714;"CALLP:RCDD1?"

ENTER 714;Rcv_data$

Setting the Display Field to Meas

When the Display field is set to Meas the top right-hand portion of the CALL CONTROL screen is used to display modulation quality measurements made on the mobile station’s RF carrier while on a voice channel.

For system type AMPS, TACS, AND JTACS the following parameters are measured when the Test Set is in the connect state. See Figure 57 .
