CALIBRATED S-PARAMETER MEASUREMENTS OF PROBES

摘要

Method and apparatus for calibrating a probe (32) including calibrating a reference plane along a transmission line, the transmission line having a first port and a second port, calculating a reflection from the reference plane into the second port with the second port coupled to a load (25), applying the probe to a physical location along the transmission line substantially corresponding to the reference plane, measuring a probe response between the first port of the transmission line and an output of the probe, and de-embedding calibrated probe parameters using the probe response and the reflection from the reference plane into the second port.
