Transient Response
Transient response analysis can determine the response speed of the output voltage of the power supply to the change
of the output load. This time starts from the first time that the output voltage exits the stable band and ends at the
last time that the output voltage enters the stable band.

Transient Response Input Setup
1.
Touch
Input Setup
to display the signal menu shown in figure
2.
Touch
Output Voltage
to set the output voltage source.
3.
Touch
Output Current
to set the output current source
4.
Touch
Duration
and turn the
Universal Knob
or use the virtual numeric
keypad to set the duration time.
–
the range is 5 ns 20 s.
–
The oscilloscope will set the timebase according to the value (duration /
10)
5.
Touch
Stable V out
and turn the
Universal Knob
or use the virtual
numeric keypad to set the stable output voltage value.
–
The range is -30 V to 30 V.
–
The oscilloscope will set the vertical scale of the output voltage channel
to stable output voltage / 6
6.
Touch
Overshoot
and turn the
Universal Knob
or use the virtual numeric
keypad to set the overshoot percentage of output voltage.
–
Overshoot can be used to determine the stable band value of transient
response and adjust the vertical scale of the oscilloscope.
