If you only need the data, simply type “load yourfile.csv” at the MATLAB command prompt. CSV files generated by Moku:Lab’s Data Logger also contain a text header with information about when the data was recorded, the instrument settings, and what each column in the data represents. If you want to import this metadata as well, use the command “moku = importdata(‘yourfile.csv’)”
For example, this is the output feedback from
>> moku = importdata("MokuOscilloscopeData_20240707_103108_Traces.csv");
>> moku
moku =
struct with fields:
data: [1024×3 double]
textdata: {9×3 cell}
colheaders: {'% Time (s)' ' Channel A (Input 1) (V)' ' Channel B (Input 2) (V)'}
>> moku.textdata
ans =
9×3 cell array
{'% Moku:Go Oscilloscope' } {0×0 double } {0×0 double }
{'% Channel A (Input 1), DC coupling, 1 x…'} {0×0 double } {0×0 double }
{'% Channel B (Input 2), DC coupling, 1 x…'} {0×0 double } {0×0 double }
{'% Time span 1.255 ms, time offset 0.000…'} {0×0 double } {0×0 double }
{'% Edge trigger: Channel A, level 0.000 …'} {0×0 double } {0×0 double }
{'% Output 1 (off) - Sine, 10.000 000 000…'} {0×0 double } {0×0 double }
{'% Output 2 (off) - Ramp, 50.000 000 000…'} {0×0 double } {0×0 double }
{'% Acquired 2024-07-07 T 10:31:08 -0700' } {0×0 double } {0×0 double }
{'% Time (s)' } {' Channel A (Input 1) (V)'} {' Channel B (Input 2) (V)'}
>> moku.colheaders
ans =
1×3 cell array
{'% Time (s)'} {' Channel A (Input 1) (V)'} {' Channel B (Input 2) (V)'}
>> moku.data
