:NAMPs|NTACs:DTMF:GATE <real number>
:NAMPs|NTACs:DTMF:GATE?
:NAMPs|NTACs:DTMF:GATE?
These commands set/query 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.
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.
