Biomation's new 820 Digital Storage Oscilloscope captures one-shot analog events, converts them to digital form, then holds them in memory. Exclusive pre-trigger recording lets you keep as much of the signal prior to the trigger point as you want. You can set the trigger level high enough to avoid false triggers. The delayed trigger stops the recording process trapping information before and after the event.

Record one test signal, change a test parameter, and test again. Then you can compare the before and after signals and their voltage and time measurements right on the display.

We've just changed the way you look at things. O u r new 820 Digital Storage Oscilloscope offers you high performance analog capture capabilities that let you trap events you've never seen before and built-in display features that let you see that information in a whole new way.
