Step 1: Create the waveform samples
Suppose you create the swept-sinusoidal signal below (the sinusoid begins at 100 Hz, increases to 400 Hz during a time interval of two seconds, and has a sampling frequency of 4 kHz):
fs = 4000 % sampling frequency tt = 0:1/fs:2-1/fs; % time vector sig = chirp(tt,100,2,400)'; % signal
Please note that your waveform vector must be a column vector, e.g., N x 1. The transpose operation in the line containing the "chirp" function converts the row vector to a column vector.
Step 2: Create the .CSV file
Next, do:
save file.csv -ascii sig
Step 3: Calculate the 33120A frequency setting
Calculate the 33120A frequency setting as follows:
fs/length(sig)
Example files
 | matlab_csv.m (create waveform data and save to a file) |
| matlab_csv.csv (file created by matlab_csv.m) |
| 0.5 Hz (frequency setting for 33120A; enter "0.0005" as the frequency in Waveform Editor) |
