Active Probes
Most Agilent active probes are compatible with the AutoProbe interface. Active probes
that do not have their own external power supply require substantial power from the
AutoProbe interface. “Quantity Supported” indicates the maximum number of each type
of active probe that can be connected to the oscilloscope. If too much current is drawn
from the AutoProbe interface, an error message will be displayed, indicating that you
must momentarily disconnect all probes to reset the AutoProbe interface, then connect
only the supported quantity of active probes.
