Add Snips Voice Control to Your Keysight Oscilloscope with a Raspberry Pi

Let’s say you’re monitoring a signal on your latest electronics project with your oscilloscope. You’ve already got your probes positioned on the tiny test points, and then you realize you need to change the scale. What do you do? If you have a Keysight 6000 or higher oscilloscope, you can just give it a simple voice command. If not, you’re going to have to manually push a button and then go through the trouble of placing the probes again. Or, you can use James Wilson’s Ollie code to add Snips voice control to your ‘scope.

Wilson’s setup will work on any Keysight 1000–6000 model oscilloscope, and all you need to make it work is a Raspberry Pi Model 3 A+ or 3 B + and a Seeed Studio Respeaker 2 Pi HAT. Wilson has provided a turnkey SD card image that includes Raspbian Lite, the necessary drivers, the Snips voice control service, and his Ollie assistant. All you have to do is flash the image to your SD card, connect the Respeaker to your Raspberry Pi, and plug the Pi into your Keysight oscilloscope with a USB cable.

Once connected, you’ll have voice commands to control a multitude of functions on your oscilloscope. For instance, you can simply say, “Hey Snips, what’s the frequency on channel one?” The Snips voice control service doesn’t require any network access, so you don’t have to worry about your privacy or security being put at risk. This is just a simple, affordable solution to make working with your oscilloscope more convenient.
