Thanks for your video! BTW, it's totally fine - and it does offer some new info on the DS1000Z. Not enough owners are publishing any in-depth info about the DSO.
A couple of points and questions:
1) The DS2000 allows measurements on MATH - both horizontal, vertical, and all - so if any of that is missing on the DS1000Z, I suspect it's a bug:
2) As mentioned in other threads on the forum, most of the new generation of cheaper DPOs (like the Agilent X-Series, Rigol UltraVision, etc) DON'T have Alt-Triggers. I theorized that perhaps the reason it's not included is because it would be difficult to support intensity-grading of two distinct time bases at a reasonable speed. In some situations, you can at least achieve a stable display of two non-time-correlated waveforms by using one of the dual source triggers of the Rigol - such as the Delay Trigger - which allows you to trigger after edges (or other conditions) from each channel with an adjustable </>/<>/= time between them. This image shows triggering on two uncorrelated waveforms:
3) Does the DS1000Z allow MATH functions using a REF waveform as a source? This is something missing from the DS2000 - and it would be nice if they would implement this function.
4) In another thread about the DS1000Z, there was some discussion of the fact that the DS1000Z appears to, at many voltage scale settings, to digitally scale (like a camera digital zoom) a smaller set (< 200) of the ADC sample values to fit the screen. This can result in a display that looks like it has horizontal stripes running through it (as in the following image). Unfortunately, Rigol fails to include this info in their datasheets (the DS2000 scales the 500uV setting). Any chance you might test this with a graded signal (such as AM signal) and see how many of the main scale settings (not the fine scale, just the coarse settings) this might be visible on?
Once again - thanks for your efforts!
