Tektronix P6131 Description:
The Tektronix P6131 is a subminiature, 10X passive probe that is designed specifically to be used with the Tektronix 2445 and 2465 Oscilloscopes. It is also fully compatible with the Tektronix family of subminiature probe accessories.
A coding pin on the BNC output connector will activate the volts/division readout-encoding circuit of the oscilloscope that will include the 10X attenuation of the probe. The compensation box houses a network that provides optimum transient response when the probe is used with the 2445 and 2465 oscilloscopes. a low-frequency compensation is accomplished by adjusting a variable capacitor through a hole that is provided in the compensation box housing.
The P6131 comes in two lengths, 1.3 meters and 3 meters.
