Gw Instek GDS2204E (200MHz 4 channel DSO) review
<< < (35/44) > >>
rhb:
With all channels enabled, they're being sampled at 500 MSa/S. You can only do 300 MHz on two channels of a 4 channel, or one of a two unless all you want to do is look at it.

I was quite amazed to discover that a 2 GS/S scope channel can go as high as 1.5 GHz, a mere 50% above Nyquist.  It works.  It's a LeCroy and it gives  220-230 pS with one of Leo's pulsers.  Both sampling at 2 GSa/S and 4 GSa/S.   But the overshoot is "<20%"!!!

For those who haven't noticed, there's a new firmware version 1.37 for the GDS-2000E series (released at 2018-11-28)

https://www.gwinstek.com/en-global/products/detail/GDS-2000E

Version 1.37
1.Fixed the  crash issue for  the "bus decode" function
2.Fixed the "peak table" data storage issue for the SA mode.
3.Added the new "SA:LIST? SCPI" command.
4.Changed the data transmission format of "SEGMents:MEASure:TABle:LIST?" (SCPI command) to  the "block data" transmission format.
5.Changed the data transmission format of " LISTer:DATA?" ( SCPI command) to the "block data" transmission format.
6.Improved the measurement high-low(histogram) calculation method.
7.Fixed the correspondence problem of frequency value for the  Math FFT Detail CSV of "Save All Waveform" function.

Have a great 2019

This scope doesn't stop!

Yesterday I updated to the latest firmware version v.1.38 (2019-01-26) and manage to activate a licence for the Spectrum Analyzer option.

After fooling around a bit with the SA functionality, I realize that I have a 70MHz oscilloscope (IDS-2074E), "upgraded" to 300MHz (EDIT: upated from 200MHz), "upgraded" again to a Spectrum Analyser with a frequency span of 500MHz  :wtf:

Attached 3 screen captures in SA mode. 2 of them from a 60MHz sinusoid (SDG1032X) with a span of 500MHz, and another from a 1MHz sinusoid with a span of 10KHz. Neat  :-+

Stretching the rope, I wish Santa could make FRA APP work with an external function generator so it could run on the GDS scopes.
nctnico:
Hmm, you didn't install the 300MHz license key?  ;D

It didn't work on my 70MHz scope. But I'm happy with the 200Mhz anyway.

PS: What is the frequency span of the SA on your stretched 300MHz scope?

UPDATE: Now I manage to have the 300MHz working. But had to clear first the file OptionConf to clean the 200MHz BW licence instaled
