Supported Active Probes and Adapters
The oscilloscope suppli es power to acti ve probe s. You ca n use the
following a ctive probes as long as the total power required by the
probes does not exceed the capacity of the oscilloscope. To
determine the tota l probe load, add the load factors for all probes you
want to use. The oscilloscope can supply power to this combination
if the sum of the l oad factors equals 10 or less. All passive probes
have a loa d factor of ze ro.

CAUTION. To avoid a measurement error, do not connect act ive
probes with a combined load factor that is greater than 10. The
signal distortion caused by such an overload can be subtle (reduced
gain, dynamic range, or slew rate).
