Fastest way of capuring data

Postby fabian » Thu Jul 02, 2015 1:26 pm


I use the Picoscope 6404D trying to collect data with the SDK and Labview.
My Question is about the differnt modes I can use for this.

I need to use the fastest timebase that is possible; which is 200 ps.
When I use the block mode, there's the problem that I can only collect a block of data points, have to transfer this to the PC and the after a time gap of typically 10-20 ms start again capturing data. This is too long for my application. Is there a way to reduce this time gap to let's say something around 1 ms or even less?

I thought this would work with the rapid block mode as the programmer's guide says about it "It reduces the gap from milliseconds to less than 1 microsecond.". How can I make this possible? Is there someone who have any experiences with this?

Remember why you started and make it work.

Hello Fabian,

If you have not already done so, please take a look at the PicoScope6000ExampleRapidBlockBulk.vi in the LabVIEW directory of the PicoScope 6000 Series SDK.

With Rapid Block mode, data transfer would occur after the device has stopped collecting data (usually via the call to the ps6000GetValuesBulk function).
