    Abstract: The disclosure includes an electro-optical sensor. The electro-optical sensor includes a test signal input to receive a test signal from a device under test (DUT). A bias circuit is employed to generate a bias signal. The electro-optical sensor also includes a Mach-Zehnder Modulator (MZM) that employs an optical input, an optical output, and a bias input. The MZM is configured to receive an optical carrier signal via the optical input. The MZM also receives both the test signal and the bias signal on the bias input. The MZM modulates the test signal from the bias input onto the optical carrier to generate an optical signal while operating in a mode selected by the bias signal. The MZM also outputs the optical signal over the optical output.

    Abstract: Disclosed is a differential test probe tip. The probe tip comprises a socket of electrically conductive material at a proximate end of the probe tip. The socket includes a concavity to receive a signal pin. The probe tip also comprises a reference body of conductive material surrounding the socket. The probe tip further comprises a insulating spacer element of nonconductive material surrounding the reference body at the proximate end of the probe tip. The insulating spacer element includes a signal port to receive the signal pin into the socket. The insulating spacer element further includes a reference port to receive a reference pin and maintain the reference pin in electrical communication with a proximate end of the reference body.

    Abstract: A flexible resistive tip cable assembly includes a probe Radio Frequency (RF) connector structured to receive a RF differential signal and a testing connection assembly. A coaxial cable is structured to conduct the RF differential signal between the probe RF connector and the testing connection assembly. The coaxial cable includes a cable for conducting the differential signal, and a plurality of magnetic elements positioned along a length of the cable and structured to isolate the differential signal from common mode interference. The magnetic elements are separated from adjacent magnetic elements by a gap with elastomeric elements is positioned in each gap to provide cable flexibility. The assembly may also include an Electrically Erasable Programmable Read Only Memory (EEPROM) loaded with an attenuation associated with the flexible resistive tip cable assembly for use in signal testing by a device coupled to the testing connection assembly.
