FM Coupling
This field alters the FM modulator to allow DCFM from internal and external
modulation sources. This field also selects ac or dc coupling between the RF
Generator’s frequency modulator and the rear-panel MODULATION INPUT
connector.
Operating Considerations
This field should be set to DC whenever the AFGen2 To field is set to FM; this
provides better modulation response at low data rates.
Function
This setting specifies which of the four types of messages to send. The pager’s
response is determined by the
Pager Type field setting and the pager’s
configuration.
For example, when testing a POCSAG pager set for tone-only operation,
functions 00 through 11 typically correspond to the pager beeping one to four
times. If the pager is set for Alpha-Numeric operation, the functions correspond to
a combination of the number of beeps and the type of message displayed by the
pager.
Mssg Length
The Message Length field specifies the number of characters output from the
Pager Numeric/Alpha-Numeric field.
This field is only displayed when the
Pager Type is set to Numeric or
Alpha-Num.
