:NAMPsNTACs:CHANnel <string> :NAMPsNTACs:CHANnel?

These commands set/query the type of data to decode.

‘Cntl’ selects reverse control channel (RECC) data.

‘Voice’ selects reverse voice channel (RVC) data.

Syntax

DEC:NAMP:CHAN ‘Cntl’

‘Voice’

DEC:NAMP:CHAN?

Screen/field equivalent

DEC:NAMP:CHAN controls the Channel field on the SIGNALING

DECODER screen when the Mode field is set to AMPS-TACSor

NAMP-NTAC.

:NAMPsNTACs:GATE <real number> :NAMPsNTACs:GATE?

This command specifies how long the decoder analyzes a signal after it has been triggered. Up to 6.55 seconds of gate time can be specified. The minimum gate time must be long enough to allow the preamble and all necessary data bits to be captured.

If the gate time is too long, the decoder’s buffer becomes full. A message is displayed instructing you to decrease the gate time.

This function is not used with the NAMPS-NTACS RVC decoder.

This command utilizes the “Real Number Setting Syntax” on page 299, but does not use the :STATe command.

Syntax

DEC:NAMP:GATE <real number>

DEC:NAMP:GATE?

Screen/field equivalent

DEC:NAMP:GATE controls the Gate Time field on the SIGNALING DECODER screen when the Mode field is set to NAMP-NTAC.
