Threshold accuracy
(Certifiable parameter)
±
(35 mV + 1% of the threshold voltage setting)
Threshold range and step size Setable from +4.5 V to --2.0 V in 5 mV steps
Threshold channel selection 16 threshold groups assigned to channels. Each probe has four threshold settings,
one for each of the clock/qualifier channels and one per group of 16 data channels.
