3.4 Display introduction
The display screen display two groups of digits, the group on the left with 6 digits shows frequency, period
and attenuation and so on of the signals. And the 5 digits on the right show amplitude, offset, duty cycle and
so on of the signals. There are also letter and letter indicator lights on the display screen, to indicate present
waveform signal, parameter options and also units of parameters.
