5-13-4 Simple Encode/Simple Decode Modes And Repeater Access Test
This mode is used to determine if a transmitter/receiver UUT is prop-
erly receiving and utilizing a signal from the FM/AM-12005, which simu-
lates the encoding and decoding processes of either a mobile unit or a
repeater (both can be tested in a similar fashion). To test these
modes, perform the following steps:
STEP
1.
PROCEDURE
Set the FM/AM-12005 front panel controls to the setting as listed
in Table 5-11.
2. Connect the UUT to the FM/AM-12005 as indicated:

For testing mobile unit Encode or Decode. connect UUT to T/R Con-
nector (11).
For testing repeater Encode, connect UUT receiver to T/R Connec-
tor (11) and UUT transmitter to 50
n
load.
For testing repeater Decode, connect UUT receiver to DUPLEX Con-
nector (14) and UUT transmitter to T/R Connector (11).
