New GW Instek GDS-2000E oscilloscope released

[Hydrawerk]

I tried this GDS-2000E scope on a trade fair. It is probably OK for the price. There are some quirks. The <- -> buttons work only in Search mode. The scope seems to be responsive.

Firmware 1.24 has been released.

Hi Tautech, do you own a GDS-2000E scope ?

A couple of days ago i contacted GW asking information about dual display FFT mode function, they promptly informed me that the related APP was just uploaded under GDS-2000E download page :

Just installed, it works good.

Cool! Scrolling the source channel up or down also works but this is much better! I did not have the time to look for other new features in the firmware. These software apps (plugins) are interesting BTW. It would be great if GW Instek released some kind of SDK and specification so people could write their own. I don't even care whether they provide any kind of support for it; I don't mind a bit of trial and error because the benefit is huge.

It works if the waveform does not touch and go over screen edges, otherwise signal start to clip and harmonics appear on the spectrum.

That is true. I forgot to add 'when the acquisition is stopped'!

The FFT app you downloaded is not available anymore for download. Removed?

[PigSpark]

And the 1.24 firmware update as well 

I have emailed them about a bug I discovered when viewing a simple trace.

3 MHz sine wave 10 Vpp, with intensity set to 0% the waveform is viewable when I set the timebase to 50 ns the trace disappears, you then have to adjust the intensity to 10% to see it.

This happens on all 4 channels.

[nctnico]

I don't think that is a bug but just how the intensity grading works. I have the intensity set to 50% on my GDS2000E.
Still I agree it is weird they pulled the new files from their website. Maybe they want to push out a newer version with some more additions.

[PigSpark]

Just had an email from GW saying they will renew the firmware mid April to resolve the issue I found. 

[Vytautas]

Good. I am waiting my ordered GDS-2072E to replace my old and faulty Rigol DS1052E and wonder what firmware version it will have installed.

[Vytautas]

Correction.
The FFT app and 1.24 upgrade are available for download in the GWInstek page, you just have to login.

I hate needing to login to see/download firmware updates!

Just received my GDS-2072E. After playing with it for a short time, I can say I am very happy with the device.
Very responsive. And full of features - segmented memory up to 29000 segments, digital filtering, event search, gated measurement capability, fast FFT (and in a separate window after the update), Autoset extremely fast. Also, 1Gs/s PER CHANNEL, memory 10Ms PER CHANNEL, 120000 wfms/s update. Brilliant. So far, have not found any bugs (though, frankly, have used it for a couple of hours yet). So far, very happy.

[Vytautas]

Here are the screenshots showing visual persistence performance of my GDS-2072E at different levels of intensity. Pretty good.

[Vytautas]

And another, pretty fortunate discovery!
The specification chart published in the manual for the GDS-2072E says that when the vertical resolution is set to 1mV/div, the bandwidth is automatically set to 20MHz. This is not true, fortunately! Here are the screenshots showing that even in 1mV/div full bandwidth is possible! Beauty!

You should check this with some real signal. 20MHz is a bandwidth limiter. I don't think it would be smart to make this setting jumping from 20 MHz to full, while changing the vertical resolution. So your "full" might be only "20MHz + a bit above" at this vertical resolution.

[Vytautas]

Here are two shots, just hooked up to a power supply, showing noise (of course, the ground lead is crap for measuring noise, but anyway, the shots show full bandwidth IS available in 1mV/div.) The older models had full bandwidth simply disabled, when in 1mV/div. It is not disabled in this model. Probably what could have happened, is that they just forgot to delete that note from the manual, which has no doubt been prepared by adjusting a previous version of a manual. I wrote GWInstek an inquiry about this. Lets see, what they will say.

[Vytautas]

I just received an answer from GWInstek. They confirmed my finding. Here is what they said: „Dear Vytautas, Thank you very much for your inputs. You are right, the BW does not limit to 20 Mhz, and we will modify our manual accordingly.“

[PigSpark]

Just been sent a beta 3 release of firmware 1.25 to try and it fixed the problem I had with the waveform intensity.

Just a short question that may not belong in this thread. Since there are Europeans here, where would buy the GDS-2000? Got my eyes on an GDS-2204E.

GW Instek has a European office (located in the Netherlands) so you could ask them to recommend a dealer: sales@gw-instek.eu
