The Tektronix P6055 is a 10× probe pair for differential amplifiers such as e.g. the 7A13 having 1 MΩ Inputs and 20 to 47 pF input capacity. The probe's resistive attenuation ratio is adjustable to an exact ×10 for the given amplifier input. This allows precise gain matching to improve CMRR.
The P6055 has a readout pin.
The P6055’s rise time is specified at 4 ns (probe only).
