Electrical signal sampling probe apparatus.

摘要

An electrical signal sampling probe apparatus to determine the response of electrical circuits or devices to ultrafast electrical pulses. The probe is detachable from the device being tested. The probe includes a transparent substrate (10) though which optical pulses are focused or directed onto a photoconducting gap (12). The probe further includes a transmission line (18, 20) associated with the photoconductive gap, and which terminates at a tapered end of the probe in contacts (22) which are placed on the device under test.
