25.10 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.
Signal Settings
Touch Signal to recall signal settings dialog box:
A. Set the output voltage source
B. Set the output current source
C. Set the duration. The oscilloscope will set the appropriate time
base according to the duration
D. Set the stable output voltage, i.e. the expected output DC
voltage of the power supply in stable state
E. Set the overshoot percentage of output voltage, which can be
used to determine the stable band value of transient response and
adjust the vertical scale of the oscilloscope
F. View the connection guide
G. Return to previous menu
Configuration
Touch Config to recall configuration dialog box:
A. Set the input low current value. This is the expected low current
value before or after the load change
B. Set the input high current value. This is the expected high
current value before or after the load change
C. Return to previous menu
Note: low current value and high current value are used to
calculate the trigger level and adjust the oscilloscope vertical
scale. After the load changes, the current value changes from low to high (or from high to
low), and the oscilloscope triggers and performs to measure the transient response
stability time.
