REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol

<< < (426/566) > >>

neslekkim:
I got my ds2202a-s today, just started it and playing around, I don't know how to make screendump yet, so I used my cellphone.

1) The model number displayed in system info is DS2202A, not DS2202A-S..

2) I see that I have the old firmware, 00.02.00.00.04 (was there a list of what is changed between this and 00.02.01.00.03?, I notice that some menutabs stays after you turn off things)

3) My serial starts with DS2E15..  I thought the A series had D, not E?, is this because this have signalgen?, or is this another way to differ models? (I saw there was written some about that the codegen does not work yet, that there probably are more keys to it, but maybe it's E in higher models now?)

4) my hardware version is 1.2.2.0.2, but other A models have 1.0.2.0.2?, is that also due to the Signalgen? (I hope the signalgen can be controlled by RUU, the menu system looks hard to use)

The rest of the numbers looks same

Where did you buy a S2000A-S version? Didn't think they were released yet. Not listed at online distributors like http://rigolna.com and http://batronix.com
Edit: they are listed at http://www.tequipment.net/rigol/series_ds2000a-series/ but without prices.

What's the price difference between the S and non-S models?

Most likely.

So is this:


--- Quote from: Teneyes on January 07, 2014, 08:42:15 pm ---These are stopped displays,  In run mode the varying trigger scanning causes the sampling to collect a series of sample along the sin display and if not a sin wave(step function) the DSO will create a sin wave overshoot.

Note : At 2.5 samples/ cycle the frequency will be accurate but Vpp is NOT.
   AS EV says very few points

--- Quote from: Carrington on December 29, 2013, 04:33:13 pm ---I think it is due to the overlap of many waveforms slightly different each time, and the wave intensity processing. Like the persistence effect.


Note: Test now with average acquisition mode and only 2 averages.

@ marmad: You agree?

Why do you think that there is nothing unusual?

Ah, I managed to miss PA0PBZ's post that you were quoting, and didn't realize you were quoting something, so I was missing the context!

That looks to be sin(x)/x interpolation (high res + persistence?) You're halving the number of sample points in the waveform by enabling channel 2, going down to one sample per division. Small changes in the sample points produce much bigger changes in the interpolated waveform because the samples are so far apart.
