The current display image is 800 by 600 pixels. The 
background color can be inverted (Ink saver 
function). Each image file is numbered 
consecutively from DS0001 to DS9999.  
DSxxx.lsf, CH1~CH4.lsf 
The LSF file format efficiently stores waveforms. 
This is the file format that is used for storing and 
recalling waveforms for measurement with the 
GDS-3000 series osciloscopes.  
Math operation result (page 82) 
Waveform files stored to the internal 
memory. Stored waveforms can be 
copied to Ref. 1 ~ 4 to be viewed on 
the display. (W1 ~ W20 waveforms 
cannot be directly recalled on the 
display).
