Just received a 2430a digital storage oscilloscope. This thing is sweet.

It’s calibrated cleaned and in beautiful shape. I’m still learning how to use the thing, but just a ton of useful features.

Huge difference between the analog and digital scope. Let’s see an analog scope do this:

I recently purchased a used Tektronix 2445 oscilloscope. It’s a 4 channel 150 MHz analog scope.

I also purchased a Tektronix 2430 digital scope which is en route. The digital scope has the key advantage that it can capture and display a single frame from a trigger. The digital scope will show readings from the Langmuir probe in the Sydney experiment.

It has taken me a few days of reading the manual and playing around with the scope to get a grasp. But I’m getting the hang of it, and wow… it’s a new way to explore the world!

My first discovery is that one of my bench DC power supplies is rather noisy:

The other bench power supply looks much cleaner:

But neither DC power supply is as clean as the perfectly flat signal you get from a battery.

I also used my iphone to display some sine waves:
