2、Click File>>New>>Script in the Matlab interface to create an empty M le
3、Add codes:
1)USBTMC access code :
Write a function Usbtmc_test.
function USBTMC_test()
% This code demonstrates sending synchronous read & write commands
% to an USB Test & Measurement Class (USBTMC) instrument using
% NI-VISA
%Create a VISA-USB object connected to a USB instrument
vu = visa('ni','USB0::0xF4ED::0xEE3A::sdg2000x::INSTR');
%Open the VISA object created
fopen(vu);
%Send the string "*IDN?",asking for the device's identification.
fprintf(vu,'*IDN?');
%Request the data
outputbuffer = fscanf(vu);
disp(outputbuer);
%Close the VISA object
fclose(vu);
delete(vu);
clear vu;
end
2)TCP/IP access code:
Write a function TCP_IP_Test:
function TCP_IP_test()
% This code demonstrates sending synchronous read & write commands
% to an TCP/IP instrument using NI-VISA
%Create a VISA-TCPIP object connected to an instrument
%configured with IP address.
vt = visa('ni',['TCPIP0::','10.11.13.32','::INSTR']);
%Open the VISA object created
fopen(vt);
%Send the string "*IDN?",asking for the device's identification.
fprintf(vt,'*IDN?');
%Request the data
outputbuffer = fscanf(vt);
disp(outputbuer);
%Close the VISA object
fclose(vt);
delete(vt);
clear vt;
end
