Thanks, in the example folder of my Matlab SDK, I find the following code which implies that the threshold value for setSimpleTrigger is in mV (and not ADC counts): %% SET SIMPLE TRIGGER % Channel : 0 (PS5000A_CHANNEL_A) % Threshold : 1000 (mV) % Direction : 2 (Rising) % Delay : 0 % Auto trigger: 0 ...

Thanks! I changed the delay in setSimpleTrigger to 0 but the same issue persists. I does appear to be an error, not a warning. It says "error" in the message and it shows up when I run Matlab's lasterror() function but not when I run Matlab's lastwarn() function. I know how to suppress warnings but ...

Hi, I'm using an external trigger signal (EXT) that is LOW normally and goes HIGH for 10 ms every 1 second. I'd like this EXT signal to trigger both the signal generator (sending out a number of sine shots) and the scope (recording a section of those shots). The code below seems to be doing the job ...

I'm using a Picoscope 5444A on a Windows 7 computer (64 Bit) in combination with Matlab 2015b (32 Bit).

Should I install the 32 Bit or the 64 Bit Picoscope SDK?

Thanks!

Thanks for your input on this, Martyn. I did a bit of research on Matlab and it turns that although there are timer functions available they will never by truly real time because at the end of the day Matlab remains single-threaded. For us it is important that the signal is very regular without occa...

Thank you for your quick reply, Martyn - much appreciated! I have two Picoscopes: a 5444A and a 5444B. I understand that only the latter one has an AWG. My 200ms sine wave bursts have to go up to 3 MHz. I take it that the AWG buffer can hold 48k samples. I don't have any experience with the AWG but ...

I'm trying to create a pulse train where the pulse consists of a sine wave (e.g. 20 KHz). The sine wave pulse lasts for 200ms, then there is zero output for 800ms, then the next sine wave pulse starts and so on. I wrote a simple Matlab script implementing the above using Picoscope's software trigger...

Hello, In our lab we have a 5444A and a 5444B. I use the signal generator to generate simple sine waves that we connect to piezoelectric ultrasound transducers. The transducer impedances are between 20 and 500 Ohm (depending on the frequency). I would like to maximize the power provided to the trans...

Thank you for your quick reply, Hitesh.

The workaround appears to be working in my first tests.

Hello, I have two Picoscopes connect to the same PC. One is a 5444B and the other one a 5444A. I was trying to read blocks from both of them (which worked well) but I find that whenever I disconnect the first scope, Matlab freezes. I was able to reduce the issue to the following bare bones code: WOR...
