% A simple example of how to create a waveform, open a
% session to the Agilent N8241A AWG, play the waveform,
% and close the session.
% Note: the waveform must be configured before
downloading.
% If settings are changed after downloading the
waveform,
% the waveform must be re-downloaded.
%
% Create a waveform - a sine wave with 2000 pts
% Played at 1250 MHz, this will produce a tone of 1.250
MHz
numberOfSamples = 2000;
samples = 1:numberOfSamples;
ch1 = sin(2 * samples/numberOfSamples * 2*pi);
ch2 = cos(2 * samples/numberOfSamples * 2*pi);
waveform = [ch1; ch2];
% Open a session
disp('Opening a session to the instrument');
[instrumentHandle, errorN, errorMsg] =
agt_awg_open('TCPIP','TCPIP0::A-N8241-90XXX::inst0::INST
R');
if(errorN ~= 0)
% An error occurred while trying to open the session.
