Probing the DUT
When making your measurements, you'll often need to probe different locations on the
DUT. You can safely move any of the following three probe heads without having to first
break the amplifier-to-head connection:
•
•
•
The only exception is when the DUT is not grounded to the oscilloscope via the AC mains
ground. In this case, connect the DUT ground to the oscilloscope ground before moving
the probe. An example of a device having a floating ground would be a battery-powered
DUT.
When probing with an N5441A solder-in probe head, always disconnect the probe head
from the amplifier before moving the head to a new probing point. This is because some
soldering-iron tips can hold a charge which can damage the probe amplifier.
Always disconnect an N5441A solder-in probe head from the probe amplifier before

un-soldering, moving to a new position, and re-soldering the head.
