Product Information

your own code: from ds1054z import DS1054Z scope = DS1054Z ( '192.168.0.23' ) print ( "Connected to: " , scope . idn ) print ( "Currently displayed channels: " , str ( scope . displayed_channels )) Author As [Alfred] notes, there are many other tools available to fetch data and images from your Rigol oscilloscope. [Jenny List] wrote a two-part series on using Python to control your test instruments, and here’s an example of a simple Python script that does a screen grab. Do you have a favorite way to remotely operate your oscilloscope? Let us know in the comments below. 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.

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.Products that weigh more than 0.5 KG may cost more than what's shown (for example, test equipment, machines, >500mL liquids, etc). This is coded in Pascal (FPC Lazarus), but we weren’t able to browse the program because [Alfred] hasn’t posted the source code yet. It is written only for Linux, and he has tested it on Ubuntu, Debian, Fedora, and Manjaro. The project relies on Python, PyVisa, and gtk2, and talks to your DS1054Z over USB or LAN. The installation instructions are well documented, but as [Alfred] himself warns, if you encounter trouble arising from subtle dependency version conflicts, you may need to be a nerd and/or a pensioner with unlimited time on your hands to solve them. There is no users guide nor extensive help according to [Alfred]. However, simple hints might be found in hover text or by pressing F1. Disclaimers aside, this looks like an interesting project to try out. The Rigol DS1054Z represents a remarkable breakthrough in price and performance. It's one of the best general-purpose 4 channel digital storage oscilloscopes available for the maker electronics space. From there, it’s basically looking at datasheets and drawing a schematic of the circuit; inputs go at the left, outputs at the right, ground is at the bottom, and positive rails are at the top. It’s harder than it sounds – most of [Dave]’s expertise in this area is just pattern recognition. It’s one thing to reverse engineer a circuit through brute force, but knowing the why and how of how the circuit works makes things much easier.

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: 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.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. Some oscilloscopes have the option to turn off sin(x)/x signal reconstruction. Not all of them do (most expensive ones don't!) because it makes no sense to do so. It's a fundamental part of signal reconstruction and drawing the wiggly lines on screen. Value, Middle Value, Lower Value, Average, Vrms, Overshoot, Pre-shoot, Area, Period Area, Period Vrms,
