As already mentioned. You should increase the airflow by using some spacers and a bit longer screws. The vesa plate covers a big portion of those air vents.
Wanted to mention this in the video but I forgot. One could do that.. Myself I'm not going to do it, User manual does not mention the need to do so, I think it was taken into account, the back panel already has part of the holes covered and the fan itself is not a high airflow one so I don't think it makes a difference. The scope itself is rated to be operated in an environment of up to +50℃ so there is quite a bit of margin.
I got a similar unit but clamps to bench top. It comes with 10mm spacers to keep mount away from scope back panel (better air flow). I can now bring scope towards front of bench when required and I can now even read small text. Best thing I ever did!
Just leave it running for a couple of hours and then measure the temperature of the front BNCs. :) Highly recommend to put some spacers between the scope and the VESA plate.

@@IanScottJohnston I've seen monitor stands that come with spacers in the past, I'm not entirely convinced thermal is the sole reason those are included. For example I had to use the spacers when I installed a monitor which had short threaded inserts so the provided screws could not be fastened all the way without some spacers.
Neat. I guess my only concern would that it swings about on the arm as you are connecting probes or pressing buttons on the scope? Apart from that, it's a win. :)
Pressing buttons is not really a problem, unless you're pushing into the top right corner which makes it move a few mm but I think you can also fix that by tightening one of the screws behind. Connecting probes is a bit more complicated to do without using two hands, you can't really do that standalone either..
Love your construction. I'm thinking about doing the same for my oscilloscope. Wouldn't the ventilation be a bit better with small distances between the mount and the oscilloscope?

Put a large touchscreen display covering all the front panels (except the probe socket) and get yourself a glorious high-end oscilloscope display like DS70000
It depends on what you're looking for and how much you use the scope for daily tasks. I'm good with the size of the display as I only use it occasionally.
There should be a more lightweight arm type. These ones are a bit too bulky. Maby one could adapt one of those flexible goose neck arms with a vesa plate...

Rigol or Siglent, upgrading firmware is an excellent sidequest that can lead to all sorts of interesting research, especially if you need to use your scope for productivity reasons and are frantically trying to recover a failed flash. Sigh.
Do you use a monitor arm with your oscilloscope? Share your experience in the comments below!
Yes, with my DHO914.....🙂
I've been jumping between a couple of stands to see in real use which one suits me best.
I think I ended up buying the same model arm support.

Yes, most of these monitor mounts come in 2 variants, table clamp or wall mount.

That's exactly what I was thinking of doing, video comparison with measurements.
You sould put some spacers between the Oscilloscope and the VESA mount to prevent impairing the airflow.

@@voltlogOf the 6 stands I tested, 3off them came with 10mm spacers for exactly this purpose which surprised me.

Cable tie a bolt if you're worried about being too light
and second in ultimate workbench - add to oscilloscope monitor with big screen

Some of the slightly more expensive monitor arms have a screw for adjusting the spring tension to match the weight of your monitor
The one I use in the video seems like a perfect fit. It's mostly behind the scope, you don't even see it.
Dave Jones reviewed this new DSO it has many bugs ,
can't capture waveform properly and much more
I wonder if they’ve updated firmware since then… @voltlog, do you know anything about this?

took them long enough to add visa mount
