*1: Multiple data can be saved in the instrument, and loaded selectively. Automatic loading at power-on is also possible.
*2: When the data is to be reloaded on the instrument, save it in binary format. Waveforms and some measurement set-
tings are saved.
When the data is to be loaded on a PC, save it in text format. (p.87)
When saving a section of a waveform, use the A and B cursors to set the section. (p.120), (p.124)
*3: When you want to use memory division and load all blocks at the same time:
Save measurement data using [All blocks]. A directory is automatically created and waveform data for each block
and index data (SEQ) is created. When loading, load this index data.
When loading waveform data of divided saving: Import the IDX index data.
*4: Loading is possible with the Wave Viewer (Wv).
*5: This is a standard Windows

graphics format. File in this format can be handled by many graphics programs.
: File type cannot be handled by MR8740/MR8741.
