Arguments
RISe specifies a
rising edge.
FALL specifies a falling edge.
EITHer specifies to trigger on either the rising or falling edge of a signal.
SEARCH:SEARCH<x>:TRIGger:A:EDGE:SOUrce
This command specifies the source waveform to be used in an edge search . <x>
is the search number.
SEARCH<x> is the search number, which is always 1.

Syntax
SEARCH:SEARCH<x>:TRIGger:A:LEVel:CH<x> {<NR3>|ECL|T TL}
SEARCH:SEARCH<x>:TRIGger:A:LEVel:CH<x> ?
Arguments
<NR3> is a floating point number that sets the threshold level to search for, in
Volts, when searching on channel <x>.
ECL sets the threshold level to a preset ECL high level of -1.3V.
