15.1.8 Connection Diagram

Before enabling the Bode function, make a proper loop connection. Click or tap Tips

to view the circuit connection diagram in the pop-up window. See the connection

diagram. Connect the rear-panel [AFG OUT] interface to the isolation transformer.

Inject the output signal of the isolation transformer to the injection resistor of the

circuit under test. Then measure the signals at the injection point and the output

point.

15.2 Cursor

The cursor is displayed as a white vertical line (as shown in

Figure 15.3

) in the bode

plot. Its X-axis value (Freq), Y-axis value of the crossover point between the cursor

and the magnitude-frequency curve (Gain), Y-axis value of the crossover point

between the cursor, and the phase-frequency curve (Phase) are displayed at the

upper-left corner of the interface. You can rotate the multipurpose knob 1 to adjust

the cursor position to view the information of each point.
