The P6205 is designed with FET devices for its inputs, which allows very high input resistance values and low input capacitances. Both Active FET probes provide a wide linear dynamic input range for accessing most digital device families using today's logic voltage levels.Power for the P6205 is supplied by the CSA, DSA, TDS and 11000 Series mainframes through the TekProbe BNC Interface, eliminating the need for extra cabling and/or external power supplies. Probe information such as type, serial number, attenuation factor, offset scale factor, input resistance, and termination resistance required is communicated through the TekProbe interface between the Active Probe and the CSA, DSA, and 11000 Series mainframes. This information is used by these oscilloscope mainframes during the initialization sequence and measurement analysis.
