Hitachi V-1065A scope...
« on: October 17, 2012, 03:53:23 pm »
Hi.  I thought that this scope has a single shot trigger mode - where the scope will capture and retain the waveform on the screen for further analysis.  The manual clearly mentioned the use of the Single/Reset in conjunction with the Normal mode to achieve this function.  So far the simple 1kHz test wave simply flashed by then disappears.  Could someone who is more used to this scope help me with this single-shot wave form capture feature in the V-1065A?  Thank you.

the V-1065A can be viewed here:

Single sweep on  an analog scope does not mean it stores the sweep. Unless it is an analog storage scope(which this isnt) you need a repetative signal to display a signal.

Many analog scopes have the ability to perform single-shot triggering, even though they don't have any storage capability.  This feature was used (back in the day) with an oscilloscope camera mounted to the CRT.  The camera would be used to capture the single trace.  There were some analog scopes that had an analog storage feature, but these were not nearly as popular as those without the persistent phosphor feature.

As the others said, it's not designed to store the signal. Very few analog scopes have storage.
Probably the majority of modern analog scopes have such a single shot mode.
Sometimes if you turn the brightness right up and you have a slow decay phosphor, you can see the signal for long enough.
A modern digital camera makes it easy to capture such a signal though.
