EDACS Decoder
This screen decodes the digital signaling data from an Ericsson GE EDACS®
(Enhanced Digital Access Communications System) transmitter. This function is
provided to test mobile radios, but it is not designed to test EDACS base stations.
Before transmitter measurements can be made, the EDACS Encoder must be set
up to provide the necessary system information. (Refer to
"Using the EDACS
Encoder" on page 388
for information on setting up the EDACS Encoder.)
Four types of calls can be decoded: group, individual, emergency, and voice
guard.

This field selects the source of the signal to be decoded. FM Demod is normally
used, since the data being decoded is usually the demodulated signaling data from
an EDACS transceiver.
