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". 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! I’ll be using the scope for debugging low speed analog signals and digital protocols/ communication.

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. note: Nowhere is it written what "sin(x)/x turned off" should be, it's undefined, it's an error condition...) I need a 4-channel scope mostly when debugging protocols and mainly never use more than 2-channels for just analog use. 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.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:

Period, Frequency, Positive Pulse Width, Negative Pulse Width, Positive Duty Cycle, Negative Duty Cycle,

Period, Frequency, Rise Time, Fall Time, Positive Pulse Width, Negative Pulse Width, Positive Duty Cycle, 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. 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.

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. 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.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.
