DECoder subsystem
:NAMPs|NTACs:DTMF:GATE <real number>
: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. 
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 command utilizes the “Real Number Setting Syntax” on page  299, 
but does not use the :STATe command.
