knowing the sampling rate, you could set the autotrigger timeout to a value that corresponds to the lenght of time taken to collect the required number of samples.

V1.1.0.78 is the latest ps4000.dll @ 15/03/2011

Using a 4227, I am getting similar transfer rates to those that you're finding.

Making sure (as you have said) that nothing much else is running will help.
Can you try it on a faster PC?

You will also need to run dpinst.exe file.

If you have a 32 bit operating system, use the DPInst.exe from the x86 folder.
For a 64 bit operating system, run the DPInst.exe from the amd64 folder. (irrespective of your processor manufacturer.)

calling the function ...

status = ps4000OpenUnitEx(&(unit.handle), "xyz12/345");

will open the unit with that particular serial number.

Is that what you are trying to do.

If you actually want to get the serial number, call ps4000EnumerateUnits.

Try the example in the latest SDK, which can be downloaded from the website

Select TC-08 Thermocouple Data Logger USB (select the product)

Select Software Development kit in step 2 (Software version)

This works.

Every 50ns, the delta phase value is added to the "phase accumulator". This is a 32-bit value, of which the top 13 bits are used as the index for the 8k waveform buffer. This means that in order to advance one sample through the waveform buffer, you must add 2^(32-13) = 524288 to the phase accumulat...

The number of samples you want to collect is the total number, so to get 10Ks/s on 2 channels you'd need to have a 20Ks/s sample rate.

You could therefore reduce the usForBlock from 60000000 to 30000000 or increase the nSamples parameter from 600000 to 1200000

As xpe & wes are just cut down versions of the full operating system, any of pico's products should work, provided all dll required are on the embedded system.

It is up to individual users to make the choice of which programming language to use, but Pico will assist with any specific questions about using the API functions.

RISING would probably be more in line with what you need, I was just concentrating on getting the pulse width trigger to work, not on the specifics.

You would need to write your own declarations for functions other than those used in the vb example. We have provided a ps2000wrap.dll for those functions that can't be called directly from vb, such as the callback functions. The source code ps2000wrap.c is provided in the sdk, to show how these wra...

Updated in SDK post R10.1.0.8

To use 2 channels, you need declare... short channels [] = {1, 2}; short nChannels = 2; and call... status = pl1000SetInterval(g_handle, &usForBlock, nSamples, channels, nChannels); status = pl1000GetValues(g_handle, &samples[0], &nSamplesCollected, overflow, &triggerIndex); The samples array will h...
