About that "5244D MSO" can't be triggered under 0V trigger voltage

Hi, everyone! :D This is the case. When I used my 5440D MSO oscilloscope for testing, I found that the signal cannot be triggered with a trigger voltage of 0V in the ±100V range: ±100V range & 0V trigger voltage can't trigger normally.jpg But when I increase the trigger voltage a little, for exa...

Questions about 5244D MSO frequency measurement

Hello everyone! When I used the 5244D MSO to test the G-pole waveform of the SMPS MOS-FET, I found that the square wave frequency with variable duty cycle displayed in the measurement toolbar is different from the result of the ruler test. Obviously, the value in the frequency measurement column is ...

Re: Is it possible to measure the spectrum of extremely low frequencies (1 to 100Hz) with PicoScope?

It can work, but to get the frequency spectrum of 1~100Hz low frequency, the display is relatively slow, more than 2 minutes.
I am using the latest version of PicoScope 6.
Is this the result? Please the administrator to answer.
Thank you! :D

Re: Question about "Window Puls width" trigger of 5244D MSO

:D Yes, Martyn. It looks like this is a problem with PicoScope 6.14.23, I updated to Everything is normal after PicoScope 6.14.36! :shock: But I have another question. Why can't the persistence mode and spectrum mode customize the sampling rate? And I found that their sampling rate is very low, so t...

Question about "Window Puls width" trigger of 5244D MSO

Hello Martyn! I set a 1KHZ square wave signal in my 5244D MSO, and then select the “Window Puls width” trigger of the oscilloscope, set the voltage range, and set the “time” to be greater than 8 nanoseconds, but it cannot trigger...... 1KHz square wave pulse width certainly larger than I set the tim...

Re: About slope trigger

Thank you Martyn!
My statement may not make you understand, what I mean is the following trigger mode, this trigger is based on the time between two voltage thresholds. It is not a simple edge trigger, I think. :oops:

About slope trigger

I don’t see the slope trigger function in picoscope 6, but I want to know if it can be replaced by other trigger methods already available in picoscope 6?
Kindly ask for your reply, thanks!

Yes, I also think it is a problem with the DEMO mode.And I have seen the truth in the operation video you provided.

Thank you Martyn! :lol:

Ask the question of "window trigger"

Hello, everyone! I found a problem when using the demo function of Picoscope 6. When I use "window trigger" a 1KHz 800mVpp signal, the waveform cannot be stabilized at a certain point. I mean, where is the trigger point for this kind of window? What is the scope of this so-called "window" on the tim...

Re: About PicoScope Test CD Optical Pickup RF signal

Yes, Martyn. :D Thank you for your reply! I did see that in some forums, someone talked about this test issue. They said that as long as it is set to slope trigger, the ideal eye pattern can be obtained. But I did not see the slope trigger in PicoScope oscilloscope software. Can other trigger modes ...

Re: The USB bottleneck myth debunked

But, why hasn't my question been answered satisfactorily yet? https://www.picotech.com/support/topic27841.html?&p=94071#p94071 No offense. I think, since picoscope's waveform refresh rate is so high, why can't it achieve the pattern I want to see? Can the picoscope 6000 series meet my needs? Because...
