The P6204 and P6205 Probes are part of Tektronix' line of Low Circuit Loading Signal Acquisition probes for CSA (Communications Signal Analyzers), DSA (Digitizing Signal Analyzers), 11000 Series and the TDS Family of Oscilloscopes.
The P6204 and P6205 are designed with FET devices for their inputs, which allows very high input resistance values and low input capacitances.
The P6204 provides wide bandwidth, with low input capacitance and the highest input resistance available. At the same time the P6204 is the only active FET probe available which provides remote control capabilities.
The P6205 provides low input capacitance and high input resistance performance at a budget price.
Both Active FET probes provide a wide linear dynamic input range for accessing most digital device families using today's logic voltage levels.
