Re: Remotely reseting picoscopes

sorry forgot to answer your questions. No they are directly connected and they are using our own software. A reboot of the PC doesn't reset them so I guess there are continually powered throughout the reboot.

Regards.

Re: Remotely reseting picoscopes

OK Thanks Hitesh.

Will the new ps4000.dll give any other options in the future?

Remotely reseting picoscopes

Hi, We have a system with 3 scopes installed in a remote location that we use with our own software. Problem is that the PC was rebooted when they were waiting for a trigger event that never arrives. On reboot only 1 of the 3 scopes can now be correctly initialised. 1 hangs the process and the other...

usb transfer speed pico 4227

Hi, I´m getting a lower data rate than expected in my own code using the GetValues call on a pico 4227. status = ps4000GetValues(unit.handle, 0, (unsigned long*) &sampleCount, 0, RATIO_MODE_NONE, 0, &overflow); This call is taking approx 3.8 secs to return 12500000 samples (from both channels so 400...

Re: pulse width trigger

Hi,

Thanks for that. Seems to trigger ok for me now.

But not sure why you put FALLING as the trigger direction and pulse width direction of RISING_LOWER. Are these because I said it was a positive pulse? What about the POSITIVE_RUNT value?

Regards,

Patrick

Re: Using ps4000GetValuesTriggerTimeOffsetBulk64 with 4227 S

Hi, I think I have the same problem here. I´m trying to get the difference in trigger times between samples collected in rapid block mode. Is there a way to do this? I have tried both of the following but they appear to be as you say the offset from each trigger event rather than an absolute trigger...

SDK for Pico4226

Hi, Just wondering if you have date for when the 4226 SDK will be available. I just tried using the 4224 SDK with it but the get_info(&unit) call doesn't appear to return valid info.

Regards,
