Abstract
Passive balanced probes are disclosed for use with a signal analysis device. The probes are very low cost relative to typical commercially available probes and provide an extremely flat response over a frequency range of approximately 0 to at least 1.5 gigahertz. The probes include a probe body constructed primarily from conventional components, a first surface mount resistor electrically connected between a probe tip and a center conductor, and two surface mount resistors electrically connected and parallel between the center conductor and a conductive shield. The probes further include a coaxial cable for connection to an instrument combiner or other instrument connection device.
