External USB Flash

drive

A USB ash drive (FAT or FAT32 format) can hold

practically an unlimited number of waveforms.

Ref A, B Two reference waveforms are used as a buffer to

recall a waveform in the display. You have to save a

waveform into internal memory or to USB, then copy

the waveform into the reference waveform slot (A or B),

and then recall the reference waveform into the display.

Waveform data

format

One division includes 25 points of

horizontal and vertical data. The

vertical point starts from the center

line. The horizontal point starts from

the leftmost waveform.

The time or amplitude represented

by each data point depends on the

vertical and horizontal scale.

For example:

–25

25 50 75

Vertical scale: 10V/div ( 400mV per point)

Horizontal scale: 100us/div (4us per point)
