Introduction

The TTRigger subsystem contains the commands available for the Timing Trigger menu in the HP 16554A/HP 16555A/HP 16555D logic analyzer module. The Timing Trigger subsystem will also accept the TTRace selector as used in previous HP 16500-series logic analyzer modules to eliminate the need to rewrite programs containing TTRace as the selector keyword. The TTRigger subsystem commands are:

∙ACQuisition

∙BRANch

∙CLEar

∙EDGE

∙FIND

∙MLENgth

∙RANGe

∙SEQuence

∙SPERiod

∙TCONtrol

∙TERM
