Tektronix recommends repeating the inrush current measurements by connecting the DUT
several times to capture the highest possible peak value. The highest possible peak value
occurs on the peak voltage cycle, and it is important to capture this point for the maximum
inrush current. It is also important to wait a few moments between connecting the DUT to
allow the input capacitance on the device to completely discharge.
FURTHER SETTINGS IF REQUIRED
Data Logging. The logging feature allows you to log repeated inrush current events in the
form of raw data. Use the DATA OUT key to log data onto a flash drive attached to the front
panel USB connector. Turn on the data logging before first connecting the device and run
the data logging through repeated plug-in events to capture all inrush events.
Screen Save. The screen save function allows you to save the current screen from the PA3000.
This can be useful for quickly capturing the inrush current readings. Press the SCREEN SAVE
key to save the data as a .bmp file to a flash drive connected to the front panel USB connector.
