About this deal

The first thing [Dave] does once the board is out of the enclosure is taking a nice, clear, and in-focus picture of both sides of the board. These pictures are edited, turned into a line drawing, and printed out on a transparency sheet. This way, both sides of the board can be viewed at once, allowing for a few dry erase marker to highlight the traces and signals. Products that weigh more than 0.5 KG may cost more than what's shown (for example, test equipment, machines, >500mL liquids, etc). This work was inspired by the efforts of [cibomahto], who spent some time controlling the Rigol with Linux and Python. 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. Do you know how to harvest data from your bench tools, like plotting bandwidth from your oscilloscope with a computer? It’s actually pretty easy. Many bench tools make this easy using a standard protocol with USB to make the connection.

The ability to easily move between long record lengths, fast capture, a variety of persistence modes, and onboard waveform analysis makes RIGOL's core oscilloscope technology an important capability for engineers from maker projects to large scale R&D. Let’s give it a try — I’ll be using a Linux machine and a popular brand of oscilloscope but the technique is widely applicable. All products in the DS1000Z series features a high-quality screen with an excellent easy to use interface that lets you access signal information such as frequency, period, rise time, pulse width and much more! Tired of squinting at the small numbers on the oscilloscope display, [Alfred] aka [Gaze@] decided to take matters into his own hands and wrote yet another tool to remotely view images from a Rigol DS1054Z. At least that was the initial idea. But, it grew unexpectedly — as [Alfred] says, “the more the project turned out to be fun, the more it got out of hand”. We know the feeling well.The basic idea was to find the signals going into the scope’s display and read them out using a Cypress EZ-USB board. This is a development board that can be used to design USB devices, and supports the UVC mode. However, with no documentation of any of the Rigol’s internal circuitry [kgsws] had to probe the display connector to find out which pin carried which signal. And since he had no other scope available than this Rigol, he hooked up the various bits of the disassembled instrument so that it could (awkwardly) probe its own internal signals. One of the big differences is that the FFT on the Rigol is joke quality (both the function and the UI) while the one on the Siglent actually works pretty well and is decently configurable. Some others are:

In the previous installment of this article we talked about the National Instruments VISA (Virtual Instrument Software Archetecture) standard for communicating with your instruments from a computer, and introduced its Python wrapper with a simple demonstration using a Raspberry Pi. We’ll now build on that modest start by describing a more useful application for a Raspberry Pi and a digital oscilloscope; we’ll plot the bandwidth of an RF filter. We’ll assume that you’ve read the previous installment and have both Python and the required libraries on your machine. In our case the computer is a Raspberry Pi and the instrument is a Rigol DS1054z, but similar techniques could be employed with other computers and instruments. What the Rigol-hater club discovered is that when you turn sin(x)/x "Off", it doesn't really turn off. Instead it changes to a "Rigol interpolation".The usage of this python script is as simple as plugging the DS1054Z into your USB port and running the script. A PNG of whatever is on the screen then appears on your drive. Testing has been done on OS X, and it probably works on Linux and Windows. It’s a simple tool that does one job, glory and hallelujah, people are still designing tools this way. The deep, 12Mpts as standard (now upgraded to 24Mpts!), memory allows you to make full use of the 1GSa/s sample rate – either for incredible zoom on a captured waveform or to maximise sample rate for a given time-sweep. The DS1054Z brings 4 channel oscilloscopes within reach of every service department, hobbyist workbench and educational laboratory around Australia. The Rigol DS1054Z Highlights

However, the issue I have, and which has been discussed endlessly elsewhere, is that the 'DOTS' mode displays dots which are not necessarily data samples. The whole point of wanting to eliminate interpolation is that sometimes you want to see the raw data that the scope is receiving so you have a better idea of what it actually knows and what it is 'reconstructing'. This is very important because the reconstruction theory depends on certain conditions being met--bandwidth limitations and so on--and sometimes there isn't an actual guarantee that they ARE met. I've seen some pretty bizarre results from this on and not just on contrived corner-case examples. I think it is a limitation, and more importantly, it isn't an obviously apparent one. Sometimes the dots are sample points--and sometimes they aren't. I'm not sure what it is doing and I haven't seen a clear explanation yet. After all the channels finish N samples at the same time, N can be 2, 4, 8, 16, 32, 64, 128, 256, 512 or 1024.

Standard logic probe for DS1000Z Plus. Upgrades a DS1000Z Plus or DS1000Z-S Plus with 16 digital channels. Ease up on the "Rigol-hater" rhetoric. The issues are more complex than that. Interpolation is involved with triggering, as well as drawing your squiggly line. IMO, the Rigol does a really good job of generating a stable trigger overall--better in fact than any of my analog scopes except the 2465B, and excepting low signal levels where some of the analog scopes trigger cleanly on much lower signals.
