Files
.wfm
Keysight Signal Studio files
Binary Files
.bin
Interleaved IQ data files. They could be single precision or
double precision customer created files. One-byte marker may
be added
CSV Files
.csv
Comma-separated value file. Could be generated by Excel
Text Files
.txt
Matlab Files
.mat
Should be Level 4, Level 5 or HDF5 MAT-files (only Level 5
Matlab file is supported in X24)
Waveforms in .csv, .txt and .mat formats are supported by models with a built-in
source, such as VXT and EXM.
.txt files are formatted according to the following rules:
1.
Text files only contain the IQ information. Data in the right column represents the
amplitude of real(I) points, Data in the left column represents the amplitude of
imaginary(Q) points
2.
The amount of data should be multiple of two (IQ pairs)
3.
The data range is from -1e10 to1e10, the data type should be int, float or
double. 16 digits or fewer for every data is acceptable
4.
The values are separated by comma or tab. Extra commas or tabs are ignored
5.
Use Enter to separate IQ pairs
