Problem for continuous capture mode

Hi, I bought some time picoScope a 2203 attempt to capture in continuous mode (without gaps) a signal of maximum frequency of approximately 4kHz for a total duration of 2 hours and keep it in a single file on my hard disk, but I was totally impossible with your device.

I can see on the screen perfectly with PicoScope 6.0.16.4 but when I try to capture it with me PicoLog Recorder is impossible or even closer to capture the signal as the minimum that I can establish is 1ms. I made a program in C + + to capture the signal but when you call the function with ps2000_run_streaming_ns parameter to false to auto_stop not to stop when you fill the buffer and can capture the memory of the device does not fire the trigger.

How can capture the same speed as with PicoScope Recorder with PicoLog?
Someone can help me or have some code that captures continuously at this frequency?

Hi

The shortest sampling period that can be used with PicoLog is, as you have found, 1 ms.

I'm not sure why you are having problems triggering with auto_stop=0. We will look in to it.

Hi

Try using the attached DLL. This should solve your triggering problem.
