TRG Input signal trig level.
PW width> Input signal positive width.
NW width> Input signal negative width.
MODE Frequency counter mode.
DEF Set configuration to default.
HFR Turn HFR on or off
Note: To use this function, you must turn on the frequency counter.
You can only set the mode, def and hfr from the above list. The rest of the
parameters are for query only.
where:
:= {ON|OFF}
:= {Input signal frequency.}
:={ Input signal duty.}
:= { Input signal trig level.}
:= { Input signal positive width.}

EXAMPLE 1
set trig level to 2v.
FCNT TRG, 2v
EXAMPLE 2
get signal frequency.
FCNT?
