Decent modern Signal/waveform Generator here in early 2024

(1/12) > >>

DaneLaw:
Looking for a relatively cheap modern signal generator, that is easy to adjust settings on. (important) and a step up from the cheap sub-100buck budget Chinese ones.

The last handful of years, been using an FY6900 DDS 60Mhz, it's been okay for the price but one annoyance is the cumbersome interface.  http://tinyurl.com/yckw8jxv
do cherish the ability to run it from the scopes USB-socket or a power bank and the mobility that comes with that.
* decent big screen, perhaps num-dial, perhaps touch, hackable?, dBm,

Budget is a relative lose 300 euros and what the alternatives are in that pricebracket (incl. VAT) its a more-or-less figure, can be more..

Wonder what direction people would go, with that budget in mind, and if they were in the market for a general function/waveform generator in early 2024?

Perhaps this isn't too helpful, as I don't know the market, but I'm happy with the Siglent SDG1032X that I use.  My biggest complaint is that the setup for an inverted pulse waveform (idle high, pulse low) is confusing.  I haven't used the arbitrary function on it yet, mostly just pulses and sine waves.  I wish it had double pulse capability; it doesn't.

I used a Rigol DG812 at work maybe sometime in 2020, and the interface was really buggy.  Otherwise, it seemed to work.  Hopefully they have much improved the firmware by now.

My requirements are not very high in terms of performance.  The main thing I look for is full 20Vpk-pk (±10Vpk) output on both channels.  Some models only give you that range on the first channel and something narrower on the second channel.

missing numeric pads is why i choose Uni-T UTG962 over FY6900. i know one day people will realize this if not mentioning it in public... UTG962 is small form factor and accepts 5V (DC jack) the drawback is trying to play arbitrary signal with it is a bit cumbersome. but i dont use arbitrary much. ymmv.

Draw your own and save it as an ARB waveform!

The Siglent SDG1000 and their entry units SDG1032 seem to have been extremely popular across the board, and the unit many people have purchased when looking for a decent sig-gen in that price bracket between 350 to 500 euros, also seems upgradeable' as far as I can tell, so no wonder its been the obvious choice for many, but it also looks like its closing in at 8 years since release which is a chunk in techworld regi, and likely not far from a new SG-version..

* SDG1032X - 30 MHz - 150 MSa/s - 14bit - 16 kpts - 2 CH - 362EURO (Incl. 25%VATDK)
* DG811 - 10Mhz - 125 MSa/s - 16bit - 2 Mpts - 1 ch - 300 EURO  (Incl. 25%VATDK) (this Rigol line also looks upgradeable, so the 1ch con could be countered)

The Owon UTG 30/60 line, is not on the plate, as it lacks some of the features, and its price is elevated quite a bit in the last few years (incl. VAT its around 200 and 250 depending on freq-model, which is around and in some cases more than double the 2019/2020 level.
