My PC become very slow when save more than 1000 waveforms

Post by rogerhk »

Hi,
My system is WinXp Sp3 with 2G memory.
PicoScope 6 version is R6.4.64
Hardware is 5203.

I capture the data every 1 minute and use save the current waveform as to save the data in .mat file (about 25000 samples one file).
I had set the number of waveforms in buffer to 1 already. But after more than 1000 times, the system becomes very slow, and as I open the taskmanger, there is still more than 1G physical memory remains but the system cache becomes more than 1G.

What's the problem?
Does the menory release after I use "save the current waveform as" to save the data in the hard disk?

Best Regards,
Roger

Hi,

You can get the settings file by going into File -> "Saving current Waveform As" and then changing the "Save as type" to be a .pssettings rather than .psdata.

Kind regards

Hi when you say save one thousand times, are you using the alarm functionality?

There seems to be no trigger selected as well.

Kind regards
