If the display at the bottom left side of the screen is "
—FFT vertical
position", use the red buttons VOLTS POSITION
▲
and
▼
to adjust the
position of the waveform along the vertical position. For example, "FFT 1.20
DIV (24.0dB)" indicates that the cursor departs from the center line for 1.20
DIV and "CH1 20dB" is shown on the bottom left side of the screen; the
arithmetic product is 24.0dB.
The operational steps are the same as above for the FFT source CH2:
11. Press the yellow

key, the following prompts appear at the bottom left
side of the screen.
— CH1 horizontal base
— CH1 trigger level
Or
— CH1 horizontal position
— CH1 trigger level
Use the
OPTION

and OPTION
►
menu buttons to adjust the position of the
waveform along the horizontal position. "FFT -2.00DIV (500.0Hz) " shown on the
bottom left indicates that the starting section of the waveform departs from the
beginning for 2.00DIV (250Hz/DIV). The displayed frequency M is the exact
frequency of the cursor point in the middle of spectrum (shown in Figure 41 below).
Use the
