Velleman WFS210 with Nexus 7

The Velleman WFS210 is a claimed to be the first WiFi oscilloscope. It has 2 channels, and 10MS/s sampling rate per channel.

See Velleman WFS210/Info for more details (such as lsusb -vvv output) about the device.

I saw this first in Maplin (UK electronics chain) priced at about £180. It seemed a lot for a 2-channel, 8 bit, 1MHz oscilloscope shipped without probes or charger, but it has some unusual features :

  • Wifi & internal battery for self-contained remote connection to a tablet or PC
  • Charges off USB (mini plug)
  • Supported on IOS, Android 4, Windows

And, much praise to Velleman for

  • Sources for Android build on github
  • Protocol description on manufacturers site
