Channel Selection can set the input and output signal channel of DUT.
a.
DUT input：Select the input signal channel of DUT, which can be CH1～CH4.
b.
DUT output：Select the output signal channel of DUT, which can be CH1～CH4.
(5) Display Setting
Set the display parameter, which can set automatic setting, gain scale, gain displacement, phase scale,
phase displacement, start frequency, stop frequency, gain display and phase display.
a.
Automatic setting: The oscilloscope is automatic set gain scale, gain displacement, phase scale,
phase displacement, start frequency, stop frequency based on the amplitude curve and phase
curve.
b.
Gain scale：Set the gain scale in waveform window, the range can set to 1dB ～ 500dB.
c.
Gain displacement：Set the gain displacement in window frame, the range can set to -250dB ～
250dB.
d.
Phase scale：Set the phase scale in window frame, the range can set to 1°～ 180°.
e.
Phase displacement：Set the phase displacement in window frame, the range can set to -180°～
180°.
f.

13-5. It can set cursor state and mode.
a.
State：Turn on, off cursor.
Turn on：Two cursors will display in bode diagram curve. Using Multipurpose knob or touch gesture
to move cursor position. The data list will display its scanning point information and the phase value,
gain value and frequency value intersecting with the cursor will display on the right bottom corner.
Turn off：Hide cursor, the relevant measured value will not display on the right bottom corner.
b.
Mode：Set cursor moving mode, which can set independent or track. Press Multipurpose knob to
switch the mode.
Independent：Two cursors can move independent.
Track：Two cursors can move in the same time.
