Siglent SDS1104X-E vs. Rigol DS1054Z Advice?
<< < (31/86) > >>
KungFuJosh:
Maybe it's just laziness, but I like hitting the autoset button. Yes, it's annoying waiting the 1 or 2 seconds while it's frozen, but it's less annoying than twiddling 3 knobs for 10 to 20 seconds to come to the same conclusion. Or maybe that's fun? Once it's set you can still twiddle the knobs to adjust the display or settings beyond that.

Pressing Storage then Default sets everything back to default on the Rigol if you're worried about the auto settings left over, and there's other undos also. But that wasn't an issue for my basic uses. I wasn't doing math functions or anything like that, just watching sine waves pooping around with it. The autoset seemed to work pretty well, even the triggering worked pretty well with some tricky stuff.

It couldn't freeze everything, but neither could I. Sometimes I had to hit the Stop button to print the ugliness I was seeing with the parasitic I'll hopefully eventually kill.

I just ordered one for $115 (best offer). Hopefully the thing works well. Thanks for the ebay idea, saved me $45 vs. the same thing I was looking at on Amazon.

Sure thing. Was that from the same vendor that had it discounted to $119 (looks like it went up a bit)? It sure is a good price. I'm tempted to get one, but I already have an HVP-70 (got it before Micsig released theirs).

$115 !?  That's a great price.  There are a few review threads of it floating around here somewhere.  It's probably more like a 60MHz probe, but for the price, it's a nice little unit.

Haha, yeah, not too bad. I started my offer at $80. ;) For my needs, 60Mhz is plenty. I could probably leave the 20Mhz bandwidth limit on and be fine. Maybe I should? I already got the tracking number, they ship pretty quick it seems. I'm in MA, and it's coming from NJ, so it'll probably be here in a day or two...before I even have a new scope to play with.
rf-loop:
Analog front end signal noise is also some diference between Rigol and Siglent.
These tests are comparable as much as possible.
(Note difference between Siglent Stdev and Rigol RMS (Rigol do not have Stdev so only way is use RMS and it include of course also DC offset)
Here Rigol is 100MHz BW and Siglent is 200MHz. If we reduce Siglent BW to 100MHz it reduce noise level around 3dB. As can see Siglent have lot of less noise even when it have double bandwidth.

Siglent have full resolution 500uV/div and Rigol have 5mV/div full vertical resolution.
With 10x probe it mean that highest sensitivity with full vertical resolution with Rigol is 50mV/div and with Siglent 5mV/div.

Other thing is that Rigol use highly decimated data for measurements. (also it map all samples to display, example here all 7Msample is mapped to display memory without decimation also for better intensity gradation so that it is dependent about one wfm data density on display and also sequential overlayed traces specially when use settings what give more wfm/s speed but less horizontal scrunch)

In this image Siglent can measure horizontally using full 1ns resolution.
But Rigol time resolution is perhaps roughly something like 10000 times less. (somewhere in forum is old thread where is exact data)

Of course all depends user needs what are important things but differencies between SDS1000X-E and DS1000Z is really huge if start looking all things. Is it even fair to compare so different things, even if some main parameters are same. What are same. Max 1GSa/s, 7" display, 4 channels and shared vertical controls. Siglent is more expensive, yes. And it is LOT of more if look its power as tool.
But only IF user need. Of course if example this Rigol 1kZ is more than enough for user needs then why pay more. It is still today lot of scope with its price!

But then, there is possible also things what user can not think before he find how useful some features are if he . Just example always background working waveform history buffer. Of course it is perhaps widely underestimated because most have never used this kind of feature and then no one talk about it - how talk things what do not have and/or know. Because most of scopes (specially low end scopes) do not have it at all or have some nearly useless "frame recorder" without full raw acquisition data.




I think difference is tiny bit more than negligible.

This is exactly right. This is a big motivator for me in purchasing the Siglent over the Rigol. A lot of people point out that the Siglent costs 40% more but I see 3 important factors:

1. Neither one of them are that expensive as oscilloscopes go. Not at all.
2. In some cases the Siglent performs 200% better than the Rigol.
3. It will cost me much less to buy the Siglent now, than it would to keep the Rigol, be disappointed by it, and then need to buy the Siglent or something else superior to the Rigol anyway. ("buy cheap, buy twice")

If it turns out I hate the Siglent, I can return it, but that's not likely.

If it turns out I never benefit from any of the better performance or features, oh well, but that's not likely either.

Now the only problem is most dealers seem to be out of stock.
