It uses the same fan PAAD16025SL PF00, and actually I don't think that anything wrong with this unit. It's just I have no other device with fan :)

Anyway, for the first look the build quality is very good. It is easily par on my HMO1002, and the BNC outputs, the rotary switch are actually much better than my scope's, so it is pretty amazing. After an hour usage it is pretty cold, so I am sure there is some room for thermal optimisation in this unit. I will get an IR thermometer/FLIR and will measure the temps in it.

The firmware is 2.01.01.16R2.

However I set the beeper off (I like the silent :)), but it forgets after switch off :/
Latest FW is 17R5:

You'd be better to check internal temps after running under some load into a 50 Ohm load, just powered on producing a low amplitude output into a high impedance load is unlikely to increase internal temps.

Yep, while the fan's not loud it a quite room you can hear it and if none of your gear has fans I now understand your comments.  ;)

My workstation has at least a PC running all the time so some additional noise would't bother me.

Comparing to my HMO's build in func. gen (10kHz, 4V), the siglent is slightly better, just a tiny bit:

Quite a pointless comparison, 10Khz sine wave from a 50Khz generator against a 120Mhz one ... if you need clean signal at audio freq use a quality sound card, it wiil draw circles around both.

I know I pushed the limits to much on this already low spec'd func. gen :D

I recently purchased a SDG2042X and just upgraded the firmware to v17R5. After upgrading the firmware I finally got around to setting up the EasyWave software and got it communicating with the 2042X. I created a new waveform in EasyWave that produces two pulses every 16.67 msec. Each pulse is 450 usec in width. The 2nd pulse occurs 2.78 msec after the first pulse occurs. Amplitude is 3.3V with a 1.65V offset (i.e. 0V to 3.3V logic pulses at output ideally). When I send the waveform to the SDG2042X the phase shift gets set to 1.65° but all other settings appear good. When I press recall I see a .bin file on the internal C: drive.

Now I turn off the unit then power it back up. After booting the settings are 1KHz and 4 Vpp with a sine wave in the graphic area to the left. After I recall the .bin file from the internal C: drive the graphic changes to the waveform I created and uploaded but the parameters remain at 1KHz and 4 Vpp. Perhaps I have a misconception but shouldn't the parameters be updated to values from the .bin file as well?

In addition, when I click on the "Read wave" button and select USBTMC connection type the SDG2042X is shown but the wave list is always empty.

I believe Read Wave is for pulling the signal from a scope. Like if you have a Siglent scope (not sure if it has to be a Siglent scope, would think it shouldn't, but it won't read the waveform from my Rigol scope) that has captured a waveform, you can connect to it and read the captured waveform from the oscilloscope into the Easywave program. Then you could send that waveform to your generator to have it produce the same waveform. Don't quote me on that, but that was my understanding of how it should work.

Edit: Ignore the above, checking in the EasyWave_Help_En help document proves that I have no idea what I'm talking about. Sorry for the bad info.

Can anybody tell me what should I choose: SDG1050 or SDG2042X? Same price for the moment, but SDG2042X looks like more "modern" and fancy. :o What is the main difference? Comparing MSa vs GSa, etc.

I would say the SDG2042X for sure.

The SDG2042X has more bits, lower jitter and way more Sa/s, IMHO the SDG1050 would have to be a lot cheaper for it to win out over the SDG2042X.  IIRC the SDG1050 doesn't allow you to add Harmonics either which I have found a lot of use for.

I don't know the SDG1050 , but the SDG2042X has excellent build quality regarding the front panel, the buttons, the knob, everything is top notch, probably finer than the old series. My main complaint, however, that it forgets all the settings after restarting :wtf:. We can store and recall the settings, though, but that is far from convenient. Solutions appreciated :)

Did you try - Utility --> System --> PowerOn=Last ?

Doesn't anyone here use EasyWave? If so, perhaps one of you might provide a response to my question posted on 4/2 (post #304).

1.  I saw your questions but don't really know the answers.

2. I've tried a number of times to use EasyWave and have yet to get predictable results.

3. It appears that the .bin file is just a bunch of samples with no timing information.  It appears that the samples are used at whatever rate you set, using your choice of DDS or TrueArb (each of which produces different waveforms from the same set of samples).

4.  Good luck.  If you figure it out please share the answers.

Same here. I haven't needed to use Easywave so far, but the few times I did try to play around with it I had trouble getting it to do what I wanted it to, so haven't really spent much time using it.

Windows is banned from my lab, mostly due to the fun around a particular chip vendor committing corp suicide while trying to fight off chip clones so I don't run it but I have been digging in trying to figure out how to just upload waveforms without their software.

It may not be an answer but hopefully I can offer one soon.  The actual wave files seem to only contain waveform data, in a very basic format.  If the voltage settings are tracked they are in a file called "SDG200X_Arb_Summary_v1.2.xlsx" which is an E-SafeNet locked file.

As this is the only .xlsx file on the filesystem it may be that they are not saving settings for custom Arb file types, but I would highly encourage you to file a bug report, and to get them to change their model.  I highly doubt anyone is going to try to pilfer their file format, and I bet they could have a healthy 3rd party software pool which would be a much larger sales driver than their Easywave software is.

I'll make a note to update this thread if I get more information, if someone else doesn't solve the issue before I get time to look into it.

Thanks to everyone who responded to my question. I'll play further with EasyWave when I have more time.

OK
So I finally close to buy Siglent SDG1025 for 330$ for Siglent sdg2042x for 470$. They are not the equal price. Which one is more value for money? Please help.

If it were me, I'd go with the SDG2042X for that amount of difference.

SDG2042X. 
If practice and theory is not equal it tells that used application of theory  is wrong or the theory itself is wrong.

Thank you very much for recommendation. I started my buying activity from GW Instek GFG-8255A which looks like stone age artefact, cost 120$, but fits my demands for the moment. But found that Siglent SDG-805 much more modern and flexible instrument than GW Instek GFG-8255A, both 5 MHz, cost 220$.
And finally Siglent SDG2042X the best choice to cover all needs of elementary hobbyist.
Can anybody PM me how to do little particular adjustment of SDG2042X with fimware 17?

You've already thanked that post  ;) and AFAIK it's done using Telnet, Google it for clues.....

I haven't done mine yet, waiting for a rainy day.  ;)

Just need a flash drive. If I remember correctly the download is a zip file. Instructions were included in the zip file for upgrading the firmware.

You'd better study the linked post and some before it, we're NOT discussing FW upgrades.  ;)
