Oscilloscope Kit Builders

Our Latest “Tech Night” – A DSO138 Oscilloscope Kit Build

Our latest Tech Night became a Tech Day this past weekend. We got together on Saturday afternoon to build another kit – the DSO138 Oscilloscope. We had a great turnout with over 15 kit builders and helpers present.

Brian, AB1ZO choose this really cool kit for us to build. Here are some specifications for the finished DSO138 Oscilloscope kit:

  • Analog bandwidth: 0 – 200KHz
  • Sampling rate: 1Msps max
  • Sensitivity: 10mV/Div – 5V/Div
  • Sensitivity error: < 5%
  • Vertical resolution: 12-bit
  • Timebase: 10us/Div – 50s/Div
  • Record length: 1024 points
  • Built-in 1KHz/3.3V test signal
  • Waveform frozen (HOLD) function available

The kit came with all Surface Mount parts pre-installed.

The kit included a very nice case to finish off the project. This was a pretty big project to complete in a single afternoon but quite a few of our builders completed their kits and got them working!

The gallery below contains more pictures from our kit build. Everyone was very focused on the building process as we all wanted to get our kits to work in the time we had together.

Some folks did not quite get their kits completed and are planning to finish them at home. The following are some links and videos to help.

Here are some videos which show the assembly of the kit and its enclosure and the operation of the completed scope. The first video shows the kit in operation.

 

 

 

 

I know that Brian is planning to do more kit builds throughout the year so be sure to keep an eye on our Tech Night page to see what is coming!
