Probes
Active Voltage Probes
Active voltage probes employ active circuit elements such as tran-
sistors in the probe body and compensation box to acquire and
process signals from the circuit under test. All active probes require
a source of power for their operation. Power is obtained from an
external power supply or from the scope itself.
Active probes offer low input capacitance (2 pF typically) while
maintaining the higher input resistance of passive probes (10 MQ
typically). Active probes are useful for making accurate timing and
phase measurements, without degradation of amplitude accuracy.
Active probes have a dynamic range of typically ±10 to± 15 V.
Some active probes are also referred to as "FET" probes. The 2212
works with the P6202A FET probe and the 1101A probe power sup-
ply for the P6202A.
