Programming Example: SDS Oscilloscope screen image capture using Python

Posted on: December 14th, 2020 by Doug Lovell

14/12/2020
Here is a brief code example written in Python 3.4 that uses a socket to pull a display image (screenshot) from a SIGLENT SDS1000X-E scope via LAN and save it to the local drive of the controlling computer.

The phase deviation between two signals with the same frequency can be easily measured via Lissajous method. The figure b...

Which oscilloscope probe is best for my application

Posted on: December 14th, 2020 by Doug Lovell

14/12/2020
Selecting the correct oscilloscope probe is very important for making quality measurements. If the probe performance is not adequate or if you did not select the proper probe for your application, you will see distorted or misleading signals on your oscilloscope. There are two kinds of probes, passive and active. Active probes requires power while passive probe do not. For general-purpose measurem...

RIGOL scope has a message on screen saying WAIT (in green). All channels ON but I see no signal being displayed. Is this effect to do with triggering?

Posted on: December 14th, 2020 by Doug Lovell

14/12/2020
Yes, you’re right: a WAIT status message is normal behaviour for the Trigger when the scope is not being given quite the right signal for its trigger to fire: - You’ll probably remember on all analogue scopes, there are at least two modes: Auto and Normal (sometimes also Single). - Normal is where the trace waits for each trigger before it starts to trace across the screen (we all remember t...

What about RIGOL battery and portable use? Can you run RIGOL Scopes and Spectrum Analysers from Battery or portable UPS Power Supplies?

Posted on: December 14th, 2020 by Doug Lovell

14/12/2020
Running the DSA815 from a battery (see also comment about other instruments) Although the size and weight of the DSA800's make it attractive for use in locations where there is no power, it suffers from the lack of an internal battery. A Google search uncovers a raft of battery backed up power supplies but the recommendation is that the DSA800's run from a supply that has a sine output. For thi...

Posted on: December 14th, 2020 by Doug Lovell

14/12/2020
We have found many instruments to be fussy about USB sticks (more common on instruments of slightly longer-standing design). Like PictBridge standard, USB memory specs can be quite open to interpretation and may vary between manufacturers. Please try the following guidelines if you are having difficulty - it is especially important you can rely on the stick you have chosen, if you decide to do ...
