SEARCH:SEARCH<x>:TRIGger:A:SETHold:CLOCk:THReshold
This command specifies the clock threshold setting for an setup/hold searchto
determine where to place a mark.

Arguments
TTL specifies a preset TTL high level of 1.4 V.
ECL specifies a preset ECL high level of -1.3V.
<NR3> is a floating point number that specifies the clock level, in volts.
SEARCH:SEARCH<x>:TRIGger:A:SETHold:DATa:SOUrce
This command specifies the data source setting for an setup/hold search to
determine where to place a mark. <x> is the search number. You cannot specify
the same source for both clock and data.
