The PicoScope software uses this functionality to ensure that all traces go through the trigger point.

As far as I understand, in this case the first 2 points in the waveform should be separated by time different from the sample period. I don't remember seeing this in PS.

Is the correction applied automatically in Picoscope?

After applying the time correction with GetValuesTriggerTimeOffset function, the 1st point time is not 0. Is it possible to consider the trigger level point at t=0 as an additional point we can add to the waveform?

Hi Gerry,
For some reason I don't see any influence of etsCycle value (as far as it is >= etsInterleave).
What is the reason for the two parameters not to be always eaual?

Are you using the latest SDK version? I had the same problem with the previous SDK.

1) In the Programmer's Guide it is noted that etsCycles is "the number of cycles to store". To store where? ps2000aGetValues returns only 1 waveform. 2) It is also noted in the description of etsCycles that "The computer can then select etsInterleave cycles to give the most uniform spread of samples...

There is a possibility to set the BW filter in the Picoscope software, but I cannot find the function in the SDK (2208B). Where is it?

Hi Mirco There is a function to get the number of sample intervals between triggers in rapid block mode but it is undocumented. The definition of the function ps6000GetTriggerInfoBulk can be found in the header file in the PicoSDK folder. The ps5000a programmer's guide has a ps5000aGetTriggerInfoBu...

Has this bug been confirmed?

Are you able to show the code which you're using? I used the PicoScope2000aExampleRapidBlockBulkMSO.vi example, but I am pretty sure it will be the same for any rapid block example. https://github.com/picotech/picosdk-ni-labview-examples/blob/master/ps2000a/32-bit-examples/PicoScope2000aExampleRapi...

Hi

In the specifications the maximum waveforms in rapid trigger mode for the 2208B is 10000.
If trying to set a value greater than this then a error will be returned by the scope to that function call.

Neil

Datasheet says that 10000 is for the PicoScope software, 500000 for the SDK.

When I try to set the number of blocks more than 32k, _ps2000aMemorySegments@12 function throws error 5030 "PICO_TOO_MANY_SEGMENTS: Not possible to create number of segments requested". This behavior is independent of the number of samples in each block, as well as x32 or x64 drivers. According to t...

PicoScope 6 is sent both downsampled and raw data, from the hardware, during a capture, and displays the data downsampled sufficiently for the zoom level selected Hi Gerry, I thought that the whole reason for downsampling is to reduce the data transfer time via USB. But you say that downsampled dat...

Is it possible to make the Picoscope software use complete data (rather than downsampled one) for math channels and measurements?

Hi Gerry,
I still cannot get what is the difference between ETS and STS. Both use delays to have more samples/s than the real sampling rate.
