1. Cursor: rotate the multipurpose knob 1 to move the cursor. The cursor information

is display at the upper-light corner of the display.

2. Bode plot curves: magnitude-frequency curve (red) and phase-frequency curve

(green).

3. Cursor information display:

- Freq: X-axis value of the cursor.

- Gain: Y-axis value of the crossover point between the cursor and the red

magnitude-frequency curve.

- Phase: Y-axis value of the crossover point between the cursor and the green

phase-frequency curve.

4. Margin result (displayed when the bode plot operation stops):

- PM: phase margin. It is the difference in phase between the phase at 0 dB gain

frequency point and 0-degree phase.

- GM: gain margin. It is the gain measurement difference between the value at 0

dB and the frequency point at 0-degree phase. That is, GM = 0 dB - Gain

Measurement Value.

5. Operation button: click or tap

to open the bode plot setting menu. Click or

tap to disable the bode plot waveform display and disable the Bode function.

Chart Display

The chart form of the bode plots is as shown in the figure below. It shows the

frequency, gain, and phase of all sample points. Click or tap

to open the bode

plot setting menu. Click or tap to close the chart and disable the Bode function.
