TEST ITEMS PROCEDURE
5. ST DEVIATION “0 1” : Suspend.
“4 6” : Initialize Vocoder in Analog mode.
“0 9 0 3 6 3 #” : Set channel to 363.
“0 7” : Carrier On.
“1 6” : ST on.
Measure the Tx ST deviation by using the HPF of 50Hz
spec : 8kHz±10%).
“1 7” : ST off.
6. SAT “0 1” : Suspend.
DEVIATION “4 6” : Initialize Vocoder in Analog mode.
“0 9 0 3 6 3 #” : Set channel to 363.
“0 7” : Carrier On.
“3 2” : SAT on.
Set the equipment as following.
RF frequency : 880.89MHz
Input RF level
: -80dBm
Modulation frequency : 6kHz
Frequency deviation : 2kHz
Measure the Tx SAT deviation by using the HPF of 50Hz
and the LPF of 6kHz (spec : 2kHz ±10%).
“3 3” : SAT off.
7. WBD “0 1” : Suspend.
DEVIATION “4 6” : Initialize Vocoder in Analog mode.
“0 9 0 3 6 3 #” : Set channel to 363.
“0 7” : Carrier On.
“3 4” : WBD on.
Measure the WBD deviation by using the HPF of 50Hz and
the LPF of 20kHz (spec : 8kHz±10%).
8. RX AUDIO “0 1” : Suspend.
“4 6” : Initialize Vocoder in Analog mode.
“0 9 0 3 6 3 #” : Set channel to 363.
“0 7” : Carrier On.
“1 2” : RX Audio unmute.
Set the equipment as following.
RF frequency : 880.89MHz
Input RF level : -80dBm
Modulation frequency : 1kHz
Frequency deviation : ±8kHz
Measure audio AC level.
