Saving to a USB Memory Device
If you press CAP and perform an operation such as changing the display mode, the acquired
screen capture data is deleted. However, by saving the screen capture data to a USB
memory device in BSG format, you can display the screen capture data on the LV 7770 even
after you restart the instrument.
Also, if you save the screen capture data in BMP format, you can view the captured data on
a PC.

device as .bmp files. You can view the saved files on a PC.
If you set

BSG to ON, the screen capture data will be saved to the USB memory
device as .bsg files. You can view the saved files on the LV 7770.

7770.
Regardless of the waveform color that you have specified, waveforms in the saved data
are white.
It takes approximately 5 seconds to save a file, and the file size is approximately 2.4 MB
for both .bmp and .bsg files.
The file is automatically assigned a name that consists of the year, month, day, hour,
minute, and second (in that order) that are set in the system settings.
