*RST: ON
This value is unaffected by save/recall.
While the Counter is configured to ON, representative CW signal(s) must be
present at the measurements input(s).
The ON setting causes the Counter to disregard any previously set "expected
frequency" ([:SENS]:FREQ:EXP[1|2|3]).
The only mechanism for disabling the above described
pre-measurement step is to specify an expected frequency with
[:SENS]:FREQ:EXP[1|2|3].
[:SENSe]:FUNCtion[:ON] <sensor_function>
Sets or queries the <sensor_function> to be sensed by the Counter.
The <sensor_function> strings are :
"[:][XNONe:]DCYCle [1]"
"[:][XNONe:]PDUTycycle [1]"
"[:][XNONe:]FALL:TIME [1] "
"[:][XNONe:]FTIMe [1]"
"[:][XNONe:]FREQuency [1|2|3] "
"[:][XNONe:]FREQuency:RATio [ 1,2 | 1,3 | 2,1 | 3,1 ] "
"[:][XNONe:]NWIDth [1]"
"[:][XNONe:]PERiod [1|2|3] "
"[:][XNONe:]PHASe [1,2]"
"[:][XNONe:]PWIDth [1]"
"[:][XNONe:]TINTerval [1,2]"
"[:][XNONe:]TOTalize [1]"
"[:][XNONe:]RISE:TIME [1]"
"[:][XNONe:]RTIMe [1]"
"[:][XNONe:]VOLTage:MAXimum [1|2] "
"[:][XNONe:]VOLTage:MINimum [1|2] "
"[:][XNONe:]VOLTage:PTPeak [1|2] "
