Siglent SPD3303D review

<< < (7/35) > >>

Zbig:
I've just found a rather hilarious firmware bug. The developers apparently cut some corners and it looks like when you save a preset (you can store up to 5 of them) it actually just dumps the RAM image to non-volatile storage. The result is, when you restore a preset, the start-up counter gets restored as well ;D I guess it's supposed to be an equivalent of a car's odometer so don't rely on it to much if you're planning on getting a second hand SPD3303 ;) Mine's firmware version is 1.01.01.01.03R1 (now, that's a mouthful).

FrankBuss:
Same in my version (I have firmware 1.01.01.01.05), it shows the start-up counter saved in the preset after restart.

But not very useful anyway. In a lab it could be started just 10 times, but running 24x7 for years, and a hobbyist could start it 200 times, but only for half an hour each time.

Exaclty, and it doesn't tell you what it's been through (powering an Arduino for whole its life or some heavy inductive loads?), either. I don't care much about it, just find it kind of funny :)

FrankBuss:
Wold be interesting to take a look at the firmware, if you want to ask for a 1.01.01.01.05 firmware update file :)

You mean ask Siglent support? Sure, why not, but I don't know their e-mail (never contacted them yet). Could you provide it, please?
