Hello,
I am currently working with a PicoScope 3425 oscilloscope with PicoScope 6.8.11.20.
It's a great tool and I think I could buy a smaller one for hobby use.
But when using the math channels, I had some problems with creating of equations and the resulting waveforms.
Even in demo mode only with channel A.
Are there problems with PicoScope 6 or have I used the wizard not properly maybe?
Regards,
ansie.
Examples:
The decimal point of the picoscopenumblock doesn't work, it has to be entered by keyboard:
The multiplication A*2,5 seems to work, but the waveform is not what I expected:
The divison A/2,5 seems to work, but the the waveform is not what I expected:
The divison A/0,5 seems to work, but there is no waveform:
The divison A/sqrt(2) doesn't work:
The multiplication A*0,7071 seems to work, but the waveform is a constant 0 line:

Re: Problems when using the math channels
Maybe try A*2.5 (dot/point, not a comma).

Hello,
I've tried it also with a decimalpoint, but PicoScope 6 then shows the red error indicator to the right of the equation box which means there exist a syntax error.
I suspect there might be a problem of PicoScope 6 with different possible regions settings of windows.

Re: Problems when using the math channels
After a testchange of the decimal separator from comma to point via WindowsSystemProperties (German XP and Win7) PicoScope 6 accepts both, comma or point, in equations (e.g. A*2,5 or A*2.5) !
The waveform with point in it's equation is now fine,
the waveform with comma in it's equation is still drawn strange.
Changing of the WindowsSystemProperties before use of PicoScope is not very useful.
So I hope very much that the software developers solve this behaviour of PicoScope 6 in further releases.
I reported the issue via the feedback function of PicoScope.

Hi ansie,
We are aware of this issue and information has been sent through to the Development Team.
A fix should be incorporated into a future release of PicoScope 6.
Best wishes,

Re: Problems when using the math channels
I realized that the problems still exist with the current PicoScope software version 6.10.11.15
I hope that the problems are fixed soon with a new version.
With this hint, the problems can be prevented temporarily:
topic14379.html
Existing math channels have to be typed in again.

Hi ansie,
You will need to continue using a '.' for the decimal separator as this was the resolution for the bug fix.
There is a feature request for Maths Channels to support other cultures so I have added your comments to that.
