Well, no more or less than some of the other more esoteric hacks we see here today anyway. Then you would have to put your face right up to it to get to see 3d images of whatever waveform you were looking at. It looked like Google Cardboard’s great grand-daddy.
Then there was a viewer thing that you had to build to go over the screen. You would hook the input to one channel along with an input source and the output to the other channel. It was a circuit that performed some sort of phase-shift on it’s input. So as long as I am in old-fart reminiscing mode, I also remember an issue where there was an article about building a 3d adapter for an oscilloscope. Actually, I’m not quite sure, was it a camera or was it actually just a box that you stick a big piece of photographic paper in and expose it that way? Either way, we sure have come far. Somewhere I have an issue of an electronics magazine from my childhood where there is an article about attaching a camera to an analog oscilloscope. Posted in Tool Hacks Tagged oscilloscope, python, rigol, Rigol 1054Z Post navigation is looking for a few people to test it out, and of course pull requests are accepted. Yes, it’s a simple tool that does one job, but if you need that tool, you really need that tool. This work will plot whatever is being captured by the scope in a window, in Linux, but sometimes you just need a screencap of whatever is on the scope that’s why there were weird Polaroid adapters for HP scopes in the day. This work was inspired by the efforts of, who spent some time controlling the Rigol with Linux and Python. It’s a simple tool that does one job, glory and hallelujah, people are still designing tools this way. Testing has been done on OS X, and it probably works on Linux and Windows. A PNG of whatever is on the screen then appears on your drive. The usage of this python script is as simple as plugging the DS1054Z into your USB port and running the script. Now there’s a simple python script that grabs a screen cap from a Rigol scope.

One small problem with the ‘Zed is the fact that capturing an image from the screen is overly complicated, and the official documentation requires dedicated software and a lot of rigolmarole. That means there’s a wealth of hardware hacks for this oscilloscope. If you don’t have an oscilloscope, this is the scope that has the power and features you need, it’s cheap, and the people who do hardware hacks already have one. So even when you trigger on a low to high signal some time later you may have different levels on different times.The Rigol DS1054Zed is the oscilloscope you want. If you have 01 and trigger on the 0 the second bit will show low and then high, but when you have 00 the second bit will show a high followed by a low, the transition (which is actually the clock) will be at the same place. If you look at a Manchester coded signal you'll see that pulses aren't always equally spaced. If you don't have a separate clock signal the data itself is used to trigger the scope. Upon a clock pulse data can be high or low, so over time you'll see both pulses on top of each other. One uses the external trigger where you connect the clock signal. There are two ways to create eye diagrams.
Infinite persistence also displays new data over the older, but the older doesn't fade, so that you can have literally thousands of images on top of each other. Normal persistence will show newer data over the previous, while older data fades at each scan. First you have to set persistence on your scope.
