SDS6000A Series Digital Oscilloscope User Manual
int.siglent.com 289
Touch Signal to recall signal settings dialog box:
A. Set the input voltage source
B. Set the input current source
C. Set the expected current value, the range is
100 mA ~ 500 A. The oscilloscope will set the
trigger level to expected current/20 and the
vertical scale of the current channel to
expected current/3.
D. 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/6
E. View the connection guide
F. Return to the previous menu
Switching Loss
Switch loss analysis can be used to calculate the power dissipated in the
switching period.
Deskew Calibration
A relatively small skew can cause a large measurement error of switching loss,
especially during the on phase when the voltage is close to zero and the non-
on phase when the current is close to zero. This is a typical oscilloscope
dynamic range limitation when trying to measure weak voltage and (or) current
in the presence of relatively large switching voltage and (or) current.
