Waveform data will be saved in the text format
while measurement continues.
Although the data can be loaded using
spreadsheet software, it cannot be loaded by the
instrument or the Logger Utility.
Waveform data is saved in the MDF (Ver. 4) format
while measurement is ongoing. These files can
be loaded on a PC using a waveform viewer that
supports the MDF format. They cannot be loaded
by the instrument or the Logger Utility.
Numerical calculation results will be saved after
measurement stops.
