Re: Get raw ADC data ps5000

UPDATE / ANSWER: It is possible to get the raw-ADC Values with the command: [status, numSamples, overflow] = calllib('ps5000a', 'ps5000aGetValues', ... get(obj, 'unitHandle'), startIndex, noOfSamples, downSampleRatio, .... downSampleRatioMode, segmentIndex, overflow); so you have to work with the li...

Get raw ADC data ps5000

Hi, Is it possible to get the raw-bit-data of the ADC in the PicoScope with Matlab? The function "getBlockData" only returns values in millivolts. Should I use the function "ps5000aGetValues"? But there I only get the status, the number of samples and the overflow or did I misunderstand it? [get_val...

Connection with PicoScope5000 c code

Hello support, I have a problem connecting my PicoScope 5444B to Matlab (C / API). However, the connection with PicoScope6 and the normal Matlab library does not work with the Matlab c code. Here is my code: setenv('MW_MINGW64_LOC','C:\TDM-GCC-64') mex -setup C++ clc; clear all; close all; loadlibra...

Re: ADC Steps PicoScope5444B

Yes, but the signal generator resolution of 14-bit shouldn't be a problem or?
Especially for the 8- and 12-bit mode

I will also do some measurements with an analog signal generator ....

PicoScope544B signal generator resolution

Hi,

what is the resolution of the Signal generator of the PicoScpoe5554B?
I can't find this value on the datasheet :/

Many thanks!

ADC Steps PicoScope5444B

Hi, I've analysed the ADC steps of all resolutions (8, 12, 14, 15 and 16) and found some interesting points and questions. I've put a triangular Signal with Vpp = 2V on one channel A with an ADC range of +-1V and oversampled it so that i got the complete spectrum back with all ADC values. Here an ex...

Re: Disable Channel B,C,D to get 16-Bit Resolution

Hi Hitesh,
thanks for your fast reply!

That was the problem!
I also found the example "PS5000A_ID_Streaming_Example" where the definition of the channels is a little easier to understand.

Regards!

Disable Channel B,C,D to get 16-Bit Resolution

Hi, I use Windows 7, MatLab2017b and the PicoScope5444B. Now i'm trying to geta 16-bit resolution on one channel (A) in Matlab , but the highest resolution i can get is 14-bit. I think the problem is that the channels B,C and D are still active, so it's only possible to get a Resolution of 14-bit. T...
