3. Turn the vertical POSITION rotary knob to define the vertical position of the time axis
in the Y(t)-window. Turn the knob counter-clockwise to move the time axis down, or
clockwise to move it up.
4. Turn the horizontal SCALE rotary knob to define the scaling for the time base in the
Y(t)-window. Turn the knob counter-clockwise to increase the scaling, or clockwise
to decrease it (and thus spread the waveform).
Note that when you change the scaling for the main time base, the width of the FFT
time base extract is also changed.
5. Turn the horizontal POSITION rotary knob to define the offset of the trigger point to
the reference point for 0s. Turn the knob counter-clockwise to move the trigger point
to the left, or clockwise to move it to the right.
Note that when you change the trigger offset, the position of the FFT time base extract
is also changed.
8.2.3 Measuring on FFT
You can perform cursor measurements in FFT mode. Automatic measurements are not
available.
1. Press FFT, then set up and configure the FFT diagram.
2. Press CURSOR.
3. In the "Cursor" menu, set the cursor lines to the required positions. Use "Prev.
Peak" and "Next Peak" to set the selected cursor line to the level peaks.
See also: chapter 6.1.3, "Cursor Menu", on page 82.
The frequency and level results are shown in the results table.
8.3 Reference for FFT key
The FFT key enables the FFT mode and opens the FFT menu.
