MATLAB Programming Demo
The program used in this demo: MATLAB R2009a
The function realized in this demo: read the output voltage, current and power measured internally on
CH1.
1
Run the MATLAB software and modify the current directory (namely modify the Current Directory at
the top of the software). In this demo, the current directory is modified to E:\DP800_Demo.
2
Click File New Blank M-File in the MATLAB interface to create an empty M file.
3
Add the following codes in the M file:
dp800 = visa(
'ni'
,
'USB0::0x1AB1::0x0E11::DP8A000001::INSTR'
);
%Create VISA object
fopen( dp800 );
%Open the VISA object created
fprintf(dp800, ':MEAS:ALL? CH1' );
%Send request
meas_CH1 = fscanf(dp800);
%Read data
fclose(dp800);
%Close the VISA object
display(meas_CH1)
%Display the device information read
4
Save the M file under the current directory. In this demo, the M file is named as
DP800_Demo_MATLAB.m.
5
Run the M file and the following running result is displayed in the command window.
