EEVblog #522 - Rigol DS1000Z Oscilloscope Quick Look

[creyc]

My DS1074Z arrived today. Ordered yesterday! 

I did some wfrm/s measurements. Input was a 20MHz sine wave. One channel active. Measured the trigger out with a frequency counter. For some time base settings the wfrm/s wasn't stable. I used a rough average then.

I also observed that the wfrm/s are depended on the displayed waveform. If the scope has more to draw it slows down. My initial signal was 4div high (peak to peak). I done another run with 1div. It was faster. This behavior makes measuring/ comparing the wfrm/s difficult.

Where did you order from?  That's QUICK

Yes, that was really quick. I saw yesterday afternoon that it is available again. Ordered it and they shipped it within a few hours.

I was watching their site for most days of the week: Friday-morning it was available again. By midday, all 4 variants were sold out again.  Like hot cakes!

But I clicked the order button in the morning on a DS1074Z-S, and I just received the box. Playtime!

Comparing some variable grade screens to my old 20MHz Analog CRO

Not bad. I think it was already clear on the video from Dave at the tradeshow the grading of DZ1000Z was not quite as good as the DS2000. But it works for what it needs to do, unlike the old 1 waveform-per-second low budget stuff I looked at when I considered buying a DSO 5 years ago. (also I admit, my budget has climbed a bit)

I used the -S internal generator, which is nice but does not do modulation or sweeping, but just adding a 1MHz and 1KHz signal also has some nice grades in it. (It actually does do AM/FM modulation, do page-down on the source setup. No sweeping though)

On the 1MHz square wave, the Rigol picture is actually nicer then the Analog.
Probably because the rise time of the square wave means the beam spends almost no time between the top and bottom edges, so as always, square wave verticals are barely visible on an analog. But the digital scope shows the fast rising vertical the same as a horizontal line. So the grade does not accurately depect how much the ratio of how much time the signal is at that voltage, but a nice pic nontheless.


BTW:If you notice the filename: "QucikPrint": another typo to fix for Rigol.

   That's just plain sloppy.

It's a foreign language to them. Everybody is a little dyslexic in a foreign language.
As long as the print-screen function actually works, I am happy enough.

I only mentioned it so maybe it seeps through into the next firmware (I am sure Rigol is keeping a close eye on Dave and this forum), but it is not critical.
