Characteristic Description
Trigger level or threshold accuracy,
typical
Edge trigger, DC coupling, for signals having rise and fall
times ≤20 ns
Trigger Source Accuracy
Any channel ± [(2% ×| setting -- net
offset |) + (0.3 div × volts/
div setting) + offset accu-
racy]
Auxiliary Not calibrated or specified
Where, net offset = offset -- (position × volts/division)
Set level to 50% function, typical Operates with signals ≥30 Hz
Trigger posit ion error, typical Edge trigger, DC coupling, for signals having a slew rate
at the trigger point of ≤0.5 div/ns
Acquisition mode Error
Sample, Average ± (1 displayed pt + 1 ns)
Envelope ± (2 displayed pt s + 1 ns)
Trigger jitter, typical σ = 8 ps RMS
