AutoProbe Interface AutoProbe is an intelligent communication and power link between compatible
probes and Infiniium scopes. AutoProbe completely configures the scope for the
attached probe. For instance, it identifies the probe type and sets up the proper input
impedance, attenuation ratio, probe power and offset range, as needed.
Main Time Base Range 100 ps/div to 20 s/div
Horizontal Position Range pre-trigger 0 to -1 s or one full screen width,
whichever is larger.
post-trigger 0 to 1 s or one full screen width,
whichever is larger.
Delayed Sweep Range 1 ps/div to current main time base setting.
Delayed Sweep Delay Range Within main time base acquisition record.
Resolution 2 ps
Timebase Accuracy 70 ppm (.007%)
∆t Accuracy* Real Time mode
4
±[(.007%)(∆t)+(0.2)(sample period)]
Equivalent Time mode ±[(.007%)(∆t)+(full scale/
(2 × memory depth)) + 30 ps]
(Example: for ≥ 16 avgs, 9 ns signal,
1 ns/div, 1 channel, then accuracy =
±[(.007%)(9 ns)+(10 ns/(2 × 65,536)) + 30
ps] = 31 ps)
