TRG <trig level> Input signal trig level.
PW <positive
width> Input signal positive width.
NW <negative
width> Input signal negative width.
MODE <mode> Frequency counter mode.
DEF <default> Set configuration to default.
HFR <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:
<state>:= {ON|OFF}
<frequency>:= {Input signal frequency.}
<duty>:={ Input signal duty.}
<trig level>:= { Input signal trig level.}
<positive width>:= { Input signal positive width.}
<negative width>:= { Input signal negative width.}
<mode>:={AC|DC}
<default>:= { Set configuration to default.}
<hfr>:= {ON|OFF}
EXAMPLE 1
set trig level to 2v.
FCNT TRG, 2v
EXAMPLE 2
get signal frequency.
FCNT?
Return:
