Are you using this line of code after you use the ps5000aGetTimebase,
This line of code will set the timebase of the scope to the Timebase variable in the line.
We will be updating the documentation to make this clearer.
I hope this helps.

Would you be able to send your matlab script to support@picotech.com so I can run it myself and workout what needs altering to get the trigger working as you intend it to?

Hi Fran The buffer is internal to the device where the data is stored before being transferred at the end of a block capture and then after the transfer it will be held in the Matlab workspace on the PC's ram rather than saved to the hard drive. There isnt a way to tell the scope that you are using ...

Hi Do you need to sample at exactly 1 ns sample interval as the 6402C can sample at 800 ps or 1.6 ns but not exactly 1 ns? It is not possible to transfer the windows of data you're talking about exclusively from the scope but it would be very easy to pick out these windows once the data is within ma...

Hi anm All the enumeration values can be found in the ps5000MFile.m in either the win32 or win64 depending on your OS. The code below shows how to turn channel B on or off. %turn Channel B on invoke(ps5000aDeviceObj, 'ps5000aSetChannel', 1, 1, 1, 8, 0.0); % Channel B %turn Channel B off invoke(ps500...

From the error message, the device object being passed needs to be changed to a trigger group object for the 3000a setAdvancedTrigger function. *% Trigger properties and functions are located in the Instrument % Driver's Trigger group. triggerObj = get(ps3000aDeviceObj, 'Trigger'); triggerObj = trig...

Hi, the USB 2.0 Y cable has about 16cm of cable between the two USB type A plugs. I cant see a reason why a thunderbolt 2 to usb3 converter would be a problem for plugging the into as they should allow the device to draw power through it as normal but depending on how it works it may only function w...

Hi, after testing with your .psdata file we believe that the reason for the average spectrum disappearing is due to the buffer on the device overflowing when the recorded data cannot be transferred quickly enough to the computer. The high sample rate and the relatively small internal buffer of the 2...

Hi,

Would you be able to post what version of PicoScope 6 software are you're using as well as the OS you're running it on?
Are you using the blue USB cable supplied with scope?
