Product Information

Modern oscilloscopes are often loaded with features, but every now and then you run into a feature that seems easy to implement yet isn’t available. [kgsws] wanted to use his Rigol DS1074 to show live measurements in his YouTube videos, but found out that this scope doesn’t support video output. Not to be deterred, [kgsws] decided to add this feature himself. In the video embedded below, he describes in detail the process of adding a USB Video Capture (UVC) interface to his oscilloscope. USB-GPIB Converter. Connect USB directly to instrument and control it via GPIB. This does not connect to a PC directly. Products that weigh more than 0.5 KG may cost more than what's shown (for example, test equipment, machines, >500mL liquids, etc).

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. We don't know the exact math of this interpolation, hence the FUD. The only 'issue' is that it's not what the OCD types think "sin(x)/x turned off" ought to be. 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.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! 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.

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". 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. 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. 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.I need a 4-channel scope mostly when debugging protocols and mainly never use more than 2-channels for just analog use. 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. It's not difficult to understand it's just that the Rigol-hater-club that inhabits this forum tries to exaggerate it beyond all reason and the details get lost.
