My 'new' Uni-Trend UTD1025C DSO has arrived - love it !

thank you Aurora, you right, rather, it is really a luxury item for me. I do not need portability so in order to pay two prices. Right, right. This is cute device but i think i give up this idea at least a year. Thank you for your wise opinion.

I wish you all the best, Dean.

I have just checked the adapter supplied with my DS1025C

It is a Regulated 9V dc 3A rated with a centre positive connector. The unit is a compact switch-mode design.

Wouldn't a plain old transformer-based DC-adapter be the better choice? I mean with a switched DC adapter, the Oscilloscope is not really floating. Can't this cause problems when e.g. the probe's GND is connected to the mains? Or to any potential of a DUT's PSU?
