Carrier Frequency Error
Command TXON (Unmod
± 300 Hz
Service monitor
set to read fre-
quency error
Refer to factory technical
support.

TX Deviation (in kHz)
Command TX7 (Modulated)
Carrier will be modulated with a
1 kHz tone.
8.0kHz
Tolerance is +5%, -10% for all bit rates.
Service monitor set
to read deviation
(IF filter set to Mid
or 30 kHz position)
Refer to factory technical
support.
6
Set the service monitor to generate at the unit antenna jack the RF levels mentioned below. The carrier generated
should be modulated with a 1.0 kHz tone at deviation as per step 4 above.
