Digital oscilloscope

Digital oscilloscope

Yesterday I got me a digital oscilloscope, the Velleman WFS210. It doesn’t look like much when you see it here on the right, but it stacks a nice amount of features.

First of all, it works via Wifi. It creates it’s own wifi network and is its own access point. Then you can access it from a Windows PC, an Android tablet or an iOS iPad (yay!).

There’s a lot of problems connecting this thing to iOS 10, on my older iPad I have not been able to establish a reliable connection. But on my newest iPad, it’s no problem (so far). Velleman really, really has to step up it’s game here!

On the back

Anyway, this is the backside of the contraption. You can charge it through a USB cable (on the right).

In the middle you see the on/off switch.

On the left we have the indicator lights for the network status.

The front end

At the front end you only find two BNC connectors. The left one for channel 1 and the right one for channel 2.

Recommended practice is to use a couple of proper probes, but I had some wires lying around from an old ‘scope, so I’m using those for now.

The result

On the right here you see the image of my 8bit computer’s clock signal.

What’s nice about this combination is that you do not have to use knobs to set your timescale or voltage range, you can do that just by pinching on the iPad screen…


I brought it back. It’s just not good enough.
