The Tektronix P6055 is a 10× probe pair for differential amplifiers such as e.g. the 7A13 and 5A22N 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.
Tektronix also recommended the P6055 for the 7D12/M2 sample/hold, because of the trimming feature improving the accuracy of voltage readings.
The P6055 has a readout pin.
