Using the EDACS Decoder
EDACS Transmitter Testing
When the mobile is turned on, it automatically tunes to its pre-programmed
control channel frequency. The Test Set generates the control channel signal using
the RF Generator and the
Control Channel
fields of the EDACS Encoder.
When the mobile is receiving the control channel, the transmitter can be keyed to
send a call request message to go to a working channel. (The working channel
settings are specified in the EDACS Encoder.)
After the mobile starts transmitting, the EDACS Decoder displays the decoded
signaling data. You can then access the DUPLEX TEST screen to make
modulation and RF carrier measurements.
Transmitter Test Procedure
This procedure establishes a control channel connection between the Test Set and
your mobile. After the mobile locks to the control channel, the decoder is armed
and the mobile’s transmitter is keyed to make measurements.
NOTE:
Each EDACS radio is pre-programmed to access a specific control channel and one or more
working channels. Other mobile and system identification information is also programmed
into the radio. You cannot test an EDACS mobile without first entering these values into the
EDACS Encoder screen.
CAUTION:
Before testing your transmitter, read the MAX PWR limit printed under the Test Set’s RF IN/
OUT port. Exceeding this limit could damage your Test Set.
Preset the Test Set
Press the PRESET key on the Test Set to set all controls to a known state and
display the RX TEST screen.
Connect the Mobile to the Test Set
Connect the antenna port of the mobile to the RF IN/OUT port of the Test Set.
