FFT represents adjusting the FFT operation
waveform
2. Trigger coupling mode display are as follows:
AC trigger coupling mode
DC trigger coupling mode
HF high frequency trigger coupling mode
3. Reading indicates the edge trigger level
position
4. Trigger status display are as follows
ARMED oscilloscope is collecting pretrigger data
under the status all triggers would be neglected

center scale
6. Symbols indicate power supply modes as
follows
7. Symbols on the screen indicate ground baseline
8. 1
symbol indicates the channel probe
multiplying power is 1
