If you mess with the fan do you loose the warranty ?
Technically yes but there where no warranty void stickers on mine  ^-^ So just store the original screws if you replace them with rubber fan mounts.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Yep, just keep original fan and screws, to put them back if need arises. If your hands are straight, there is nothing to worry about. If I do something like this, I also wear ESD gloves to avoid leaving any fingerprints inside  :-DD.

Anybody here feel up to doing the new "Wolf" test?

Apply a square wave to an input, display "rise time" on screen, then zoom in and out.

The idea is to see if the rise time is computed with screen pixels or with sampled data.

If the displayed rise time varies then it's using screen data.  :popcorn:

"Wolfs test" thread is here:
https://www.eevblog.com/forum/testgear/testing-dso-auto-measurements-accuracy-across-timebases/

It should be interesting since GW Instek seems to have excellent engineering team. Just bit lacking on marketing side  :'(

May I ask you if 10Mpts setting is per channel or overall. E.g. if you sample 4 channels, do you get 10Mpts for each (40Mpts total) or is the overall amount spread around channels (e.g. you get 5Mpts or even 2.5Mpts when you have all 4 channels on).

Actually more: With 10MPts you can still get 2 segments which means there is 20Mpts of memory per channel if you calculate the memory like Keysight does it.  >:D

Ntcnico, would you buy the gds-2204E again today? Instek 2204E is $1256 USD right now. I won't spend over$1300.

I've ruled out siglent 2000x series. Don't think R&S, Tek, BK, nor Rigol have anything competitive with 4 channels in my budget.

I don't want to ignore a strong competitor. What are your thoughts?

Definitely yes. Currently it sees more use than my very expensive Agilent scope.

They seem very similar in specs. Siglent has 2gsa/s but instek has more FFT points. Siglent has more memory but Instek seems to have better firmware support. Instek serial decode seems robust in context of DSO (over Siglent).

Between their differences I personally like what I see on Instek more and my fuzzy logic after much reading and some sleeping is pushing me strongly to Instek.

I've ruled out siglent 2000x series.

It seems firmware version 1.27 has been released and on GW Instek's site it is tagged as 'GDS-2000E / MSO2000 series firmware'. I have not tried it yet.

New version of the GDS 2000E series, the MDO2000E series with AWG option.

http://www.gwinstek.com/en-global/news/28/140236

MSRP not published by Instek to date but there are vendor prices posted for the EU market for those who stock it.
Best Wishes,

Interesting! Also the 10Mpts for the MSO part is nice. Ofcourse this extension was to be expected because the firmware for the GDS2000E already had references to digital channels for a long time.

It seems the price for the most complete model is around 1900 euro ex. VAT (including decoding, MSO probe, etc).

@nctnico @saturation May I propose splitting the discussion on the new MSO series into a new thread

https://www.eevblog.com/forum/testgear/gw-instek-announces-new-mso-2000/

and keep this thread focussed on the "original" GDS-2000E (unless specific comparisons arise).

Thank you

Does anyone actively use the remote mount feature?  I used it for  a few weeks, and it was nice to offload images instantly.  It no longer works, and doesn't attempt to connect.  I'm unable to erase the settings, or get any further debug.  I reached out to support months ago, but they didn't offer a solution.  Just curious if anyone else has seen this problem.

My other ask from support (besides a way to wipe it clean), was for login info.  Has anyone gotten that yet? I tried swapping out hash's but something about ubifs must validate the bits changed and reject the patched firmware.  I didn't try too hard and don't know much about ubi.

My ongoing disk mount Error is "Mount remote disk fail.", it's persisted through all firmware updates and resets and attempts to factory default, app removal re-installs.  It kills me that I can't just log in and fix it.  Especially when there is a damn ssh port listening on it's network interface.

Otherwise I'm pretty happy.
Thanks for all the info in this thread.  Hope it's cool I posted this here.

Did you check the file server logs? Maybe something changed on the system you are trying to connect to. Also try another network cable (even if the cable you use now seems to work) because many network problems are caused by cables.

It's working again. 
Thanks for the thought.  I had run tcpdumps and all kinds of things previously, and indeed it's all my fault.  caught it trying, and fixed it.

Am I overlooking something, or is there no user-definable baud rate for the UART serial decode?

I have access to a 2204E, and was trying it out on a system with a UART stream generated in programmable logic with nonstandard bit rate, and was only able to select standard baud rates.

This comes up every once in a while, and it's an oversight not to include user definable/adjustable bit rates for serial decodes in general.  This seems like either an oversight in the decode module or in the UI (making it hard to find.)

You can do this for sure (maybe this has been added in a recent firmware release). If you select a baudrate you can turn the 'variable' knob to select a custom baudrate.

It must be in a firmware update.  What's the latest version?

I have v1.24, and the baud button allows me to select standard baud rates with the 'variable' knob, but there is not an obvious way to select a nonstandard rate.

Also, does anyone have a working link for firmware updates?  It doesn't seem to be on the GW instek page.

The most recent version is 1.27 (30 Jan 2017). You have to create a login in order to see the download on GW Instek's website. I know:  :wtf: and  :palm:

As I recall this scope was released about a year ago. How likely will Gw Instek release an updated version this year?
