Abstract :
The balanced coaxial probe is a valuable high frequency measurement tool that avoids the limitations of conventional probes, active and passive. Its resistive input impedance and balanced design are the keys to making clean measurements in the 1 to 500 MHz range. In fact, this probe represents an extremely effective method to accurately measure a high frequency voltage between nodes a few inches apart, as the required lead lengths for such measurements cause severe overshoots for "normal" probes with capacitive input impedances.<>
