High Impedance Active Probes
7A
An unterminated version, can be used for capacitance and resistance measurements or in low to medium speed signal applications where a 50 ohm termination is not required. A flexible coaxial cable length of 6 feet in length is standard on the Model 7A; however, when used for capacitance measurements, GGB Industries, Inc., recommends using a shorter 3 foot cable. If a shorter length of cable is desired for capacitance measurements, please specify it when ordering (Model 7A-3ft.). Please note that Model 7A uses Model 7 replacement tips.

High Impedance Transformers
Osborne high impedance transformers are used to step-up, step-down and isolate voltages in single phase and three phase circuits. A properly designed high impedance transformer can be used an an equivalent to an isolation transformer connected in series with an inductor. The high impedance characteristic may be employed as a current limiting feature in both the primary and secondary circuity.
