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.
Four characteristics of the RF carrier are measured: TX Freq Error, TX Power,
FM Deviation, and AF Frequency. The
Meas information is only available in the
connected state (that is, the
Connect annunciator is lit).
Figure 36 on page 449 shows the layout of the CALL CONTROL screen when Meas
is selected.
