Title: Phase Angle Oscilloscope reading
Post by: threephase03 on May 28, 2023, 01:37:28 am

Hi All

Does anyone know of any oscilloscopes that can display the phase angle between two signals without having to adjust lines etc.

Cheers in advance

the rigol 1054z, the keysight 1000x series, the analog discovery(more its software, so all the waveforms compatible devices) all have phase between 2 channels as a predefined automatic measurement that you just have to enable under the scope's measurement options. i mentioned those 3 as those are the ones i have that have the phase masurement, but i would think most other modern oscilloscopes also have automatic phase angle measurement

Hello,

should be possible with every scope with math functions (even if there is no dedicated menue):

Whilst the above post is still correct the most recent version of PicoScope 7 can also plot a graph of the phase change between 2 channels using the built in phase maths channel function.  See oscilloscope phase measuremes article https://www.picotech.com/library/oscilloscopes/phase-measurements-and-math-channels (https://www.picotech.com/library/oscilloscopes/phase-measurements-and-math-channels)

This looks pretty sick, tempted to buy it just to have fun with it.

Cheers mate

Andreas and ADT123 - thanks for posting about the new features in Picoscope 7!  I have been one of the users that has requested this feature at least a few times, and I had not realized it had been released.  I just now downloaded the latest 'Early Access' and there it is!

Cheers!
