The Agilent 10020A Resistive Divider Probe Kit is a signal probing system for measuring fast-transition-time signals in high-impedance systems. It is designed for use with 50 Ω input oscilloscopes, but may be used with other than 50 Ω systems if a 50 Ω feedthrough termination such as the Agilent 10100C, is used.
The Agilent 10240B Blocking Capacitor is a probing accessessory that provides ac-coupling while maintaining a 50 ohm system. This capacitor is designed for use with the model 10020A Resistive Divider Kit, but may be used with any probe that must be terminated in 50 ohms.
