Import user-define waveform file
Users can edit a user-defined waveform file in .csv format and import it into the
instrument. User defined harmonic waveform template files can be obtained by
contacting ITECH, or an empty file can be exported directly from the instrument.
The user-defined waveform template description as follows:
Model: keep default
operation mode of instrument, 0: voltage source, 1: load, 2: current source,
Users are cautious to modify, the waveform files are not common in different
modes.
Usage: Usage, keep default
Name: keep default
Type: Waveform type, user-defined waveform is 9, which must be 9 in this file.
Editable: keep default
Point_number: The number of data points to be edited, which needs to be
consistent with the data row in the table. Associated with the Origin_symm
parameter.
Origin_symm: symmetry option, 0 represents 512 non-origin symmetry, 1
represents 512 origin symmetry, 2 represents 1024 points.
Index/fval: Data points and detailed parameter values.
5.15 Voltage Sampling
The IT7900P series instruments can be used as data sampling devices to collect
voltage variation signals from other instrument. With this function, users can
realize the acquisition of the actual grid voltage change state of the DUT, and
then use the import function to reproduce the grid state.
Connecting method
When the voltage signal is sampling, the wiring method is the same as the test
line connection method when outputting. For single-phase, connect the two
