What it does
On the DHO800/DHO900 roll runs at 5 ms/div and slower, ten times faster than the 50 ms/div Rigol's firmware stops at, with every sample arriving on one, two or four channels. The MHO900 rolls from 50 ms/div until the same measurement is made on it.
Roll and the trigger are chosen apart. In roll, SINGLE keeps rolling until the edge arrives, then on until it reaches the trigger point, and stops there; NORMAL holds each triggered screen for a moment; AUTO rolls freely.
How to use it
- Acquire sheet, Roll: On takes the time base down to 5 ms/div; Auto rolls from 50 ms/div or a time base you set beside it.
- Set an edge trigger and press SINGLE to stop on it while rolling.
On Rigol's firmware
DHO800: from 50 ms/div · DHO900: from 50 ms/div · MHO900: from 50 ms/div.
