Siglent - 11/20 - New SDS1104X-U, 4 channel 100MHz, 1Gsa/s economy oscilloscope

<< < (19/32) > >>

LiftedTrace:
I just recently purchased a Rigol DS1054Z (just before the Siglen seems to have been released.) I dont use anywhere near all the features, but I am a bit on the child hood greedy side though and have to wonder....should I return this Rigol and get the Siglent SDS1104X-U instead?
The Siglent being fairly new and the Rigol being quite dated. Would it be worth my time to do a swap them out? Reading thru this posts it seems the Siglent is better, but its also about $50 more.
Anyone have thoughts on this?

a) These aren't smartphones, life doesn't move fast in the oscilloscope world. The difference between the two isn't really much.

b) The "new" Siglent is just a cut down version of a previous model Siglent which is nearly as old as the Rigol.

It's about $50 better. Whether you send it back and cost the seller money on a whim is between you and your greed.

If you want something that really feels new and "next generation" then get a Micsig.

(that's what I did - I went from Rigol to Micsig and I'm loving it)

Well, you keep repeating that, implying it's a better instrument than both DS1054Z and SDS1104X-U..
It is not, it's just different, has some things better, some worse...

It depends what you do. For instance, STO1000C doesn't have statistics on measurements, and not even AC RMS measurement. It doesn't have table mode for decode, but it has dedicated decode in full screen text mode, that doesn't work with zoom or signal view in general, and doesn't allow you to switch between views. If you do switch modes, you lose captures. You cannot tap on packet and make it show it to you in waveform view..
It has no segments, not even basic ones DS1000Z has..
OTOH, it is really portable, front end is low noise, and what it has, works pretty well with very few bugs.

But it is very basic scope, with some eclectic mix of features. It has filtering and quite good math, but no statistics on basic measurements..
It has no segments, but has segments button..To me it almost seems like it was released unfinished...
Text mode decode looks like an afterthought that is not integrated into scope but works as a separate acquisition mode. That gives it some pretty powerful capabilities, but also takes away many, so it is very limited, instead of better...

And it is quite a more expensive than those two.

I have it, and I'm not regretting buying it. It paid off very quickly, because it is a very useful handheld scope. But it would be very awkward  to have it as single scope to own. And I'm not talking about user interface. I only have touch screen scopes, and will never go back to non touch screen ones.
It is the awkward mix of some very advanced features combined with missing some basic features and some conceptual choices that makes it questionable choice for first and only scope.

But as I said, it depends what you do.

You can't deny it feels new and "next generation" though.

They're currently working on statistics, at my request.  :)

(or so they tell me)

Twisty knobs are bad! At least we agree on that.

The entry-level Rigols/Siglents being discussed here can't do everything, either.  :-//

Serial decoding is way better than on Rigol/Siglent.



(nb. The silly sound effects can be turned off)

Yes, you go to a separate screen to record/view the incoming data but I don't see a problem there because:
a) It does the live/on-screen decoding too, just like the others.
b) You can let it sit in text mode and record all the incoming data, it's not limited to just whatever's in the sample memory at any given time.

Saving to USB stick is also easy in text mode - the "Quick Save" button at the bottom of the screen is modal so when you're in text mode it dumps the recorded serial data to a .csv file when you press it.

Yes, it is a good little thing. I really like it or what it is but it has it's cons too.
Twisty knobs are not bad, best U/I is knobs for basic, obvious stuff, supplemented with touch screen for stuff that is better used that way.

Glad to hear about statistics.. If you're communicating with them, remind them on AC RMS measurements.

Text mode works great, in text mode it uses special acquisition mode, that allows it to decode huge number of packets, basically replacing need for segmented mode for long decoding.
But you loose completely the whole idea of scope with decoding: correlation of decoded packet to an analog event on other channel.
You cannot select that packet and switch to waveform mode to see what was happening then...
It converts a scope into 4 ch 10 USD logic analyser....

The advantage comes from the fact that it has enough capability to get you out of trouble out in the field...
And it makes great second scope, for usual scope work...
