Faulty signal generator on 5244B

Hi The signal generator on 5244B has a problem. Sometimes it is making periodic "flat pauses" when it is supposed to generate a continues sine. I have used a second scope to investigate the problem (I did not believe it in the beginning). The second scope was trigging only on these flat pauses. The ...

Re: PicoScope Beta 6.9.5: Duty cycle graphing

Great to see that PicoScope is defending its position as the worlds best scope, by adding new features to a great program! Thank you, the developers, for adding this and many other features :D I have one question regarding the duty cycle: Don't you need a time-constant, or a window-length within whi...

Re: Matlab

Can you be a little more detail about what to do? It sounds interesting, but it also sounds Greek.

Re: Matlab

On windows 8.1, and Matlab R2012b, I get this message:

"C:\Users\..\matlab\mqair\PS5000.dll"
C:\Users\..\matlab\mqair\PS5000.dll is not a valid Win32

Re: Matlab

Hi I have one (old) PS5204. I am very happy with the device, except when I try to control the device with Matlab. I have got things working, only to see it stop working when I changed version of Matlab and/or version of windows. It seems to me, like you have better support for some picoscope series,...

Re: PS5000 Load Library Error

Hi Hitesh,

Yes, I have access to the Instrument Control Toolbox, I just wonder, if it will be any easier to connect to the new PS5000. Is it tested on a few PCs?

National Standards Calibration Service

Hi, I am thinking very much about buying a 5244B. I am not sure if I need the calibration service. The only reason I can think of is the timebase accuracy (drift). The datasheet states that it is ±2 ppm (±1 ppm/year). I want to know, how much more precise does it get? Is the NS calibration service a...

Re: PS5000 Load Library Error

Hi Hitesh, Thanks for your answer. I have yet to read the link, but regarding the question; Yes, it is 64bit, on Win64 . R2012b (8.0.0.783) 64 bit (win64) I have one more nagging question: I plan to change from my good old PicoScope 5203, to 5244B. Will that affect the matlab program? If so, maybe i...

Re: PS5000 Load Library Error

HI Hitesh, Thanks for the help I think, I am almost through, but I still get the same error message same line. I can see that the file size of the dll has changed since last time I downloaded them some years ago. What is the mfilename good for? In the command prompt it is empty. Best Regards, Gustav

Re: PS5000 Load Library Error

Hi Hitesh,

Thanks for the reply, but you need to be more specific. How do get the 64bit version of PS5000.dll? And how is the prototype recreated?

Best regards,

Log sweep mode

I am doing some measurement involving EMG signals (but it could also have been sound, the suggestion would have been the same). For the output signal generator, the sweep can either be up or down in a fixed steps. It would be much more practical to have a log scale. Imagin testing a loudspeaker, you...
