25.8 Output Ripple
Power supply ripple is an important parameter to evaluate DC power supplies, which
represents the quality of output DC voltage. Ripple analysis can measure the current
value, average value, minimum value, maximum value, standard deviation and count of
the power supply output ripple.
Connection Guide
Touch Signal>Connection Guide to recall the connection guide of output ripple, as
shown in the figure below. Please follow the instructions in this figure for connection.
Touch the icon on the top right of the guide to close.
25.9 Turn On/Turn Off
Turn on analysis determines the time taken for the power supply to reach 90% of its
steady-state output. Turn off analysis determines the time taken
for the power supply to fall to 10% of its maximum output
voltage.
Signal Settings
Touch Signal to recall signal settings dialog box:
A. Set the input voltage source
B. Set the output voltage source
C. Set the input type (AC or DC)
D. Set the duration, the range is 5 ns - 20 s. The oscilloscope
will set the timebase according to the value (duration / 10)
E. Set the maximum effective input voltage Vrms, the range is 1
V - 1 kV. The oscilloscope will set the vertical scale of the
voltage channel to maximum input voltage / 7 and the trigger
level to maximum input voltage / 10.
F. Set the stable output voltage value, the range is -30 V - 30 V.
The oscilloscope will set the vertical scale of the output
voltage channel to stable output voltage / 6
G. View the connection guide
