What are the valid voltage ranges and edge triggering values for NI5911

[hallow]

I was wondering: what were the valid inputs for the vertical voltage range?
Also for a given vertical voltage range what are the valid levels to input for an edge trigger?
Specifically for the NI 5911 high speed digitizer. Thanks

Vertical sensitivity (input ranges)
±10 V
±5 V
±2 V
±1 V
±.5 V
±.2 V
±.1 V

Triggering:

Full-scale voltage/n, where n is
between 1 and 170; full-scale
voltage on TRIG is fixed to ±5 V
(without external attenuation)

All these specifcations can be found in the user manual, which you can download from:

Hope this Helps.

what happens if I enter a vertical range other than valid vertical input ranges. the digitizer still seems to work. Is it choosing the next higher value or the closest value?

[kroth]

You are correct the digitizer will still work. When you input your voltage range, the scope will choose a sensitivity level that will handle that voltage. So in answer to your question it will choose the next higher range.
