One important piece of information (at least for me) that gets lost when exporting psdata to MAT or CSV is the time-stamp of each waveform in the file. Adding it to MAT files should be very simple, since the datablock definition is very flexible - just add another data block with this info. For CSV ...

Thanks you,

Will check again the voltage issue, since my impression was that the values read from the MAT file did not correspond with those displayed when I looked in PicoScope at the psdata file.

OK - I think I figured it out Tstart and Tinterval - they seem to be in seconds. I used a hex editor to find the values and used a binary to double converter. Please confirm that my assumption is correct. The Length parameter seems to be the number of samples - please confirm. still have problem wit...

When exporting to MAT files there are the variables - Tsart and Tinterval.
What units are they in?

Thanks,

Is there a VB/VBA example of fast streaming?

I will try working both with block and streaming. In fast streaming the function prototype in the documentation says that the interval passed is in PS300_TIME_UNITS. The C++ example shows that this is an enumeration, however I am not using C or C++. What is the data type that the dll expects (a byte...

I am in the process of writing an application (RealBasic) as follows: Scope is 3425 working with two channels - per specs this allocates 256K per channel internal buffer. Required sampling rate - 10uS (100kS/sec) The collection is a random triggered event, after which I would like to collect about 5...

Thanks,
That confirmed my assumption, and according to my understanding the 100meg limit is hard coded and cannot be changed - correct?

I set in preferences "max waveforms" to 1000, so I expect to be able to capture 1000 waveforms. The "number of samples" at the top of the scope screen is set to 100kS - If I understand correctly this is the maximum samples per waveform captured (actual number varies - did not yet understand the logi...

Although I set the number of maximum buffers to 1000, I see that the highest number is lower (depending on timebase) - multiplying the number of samples per buffer with the number of buffers actually captured it seems to be limited at something around 30 megasamples (maybe it is 120 as I use 2 chann...

I would like to make sure I understand the streaming mode and the "switch to slow speed" parameter: 1. When the sampling rate is FASTER than the parameter the scope switches from streaming to block. Correct? 2. What is the fastest sampling rate in streaming mode for the 3245 working with 2 and 3 cha...
