An oscilloscope probe includes: a connector pod; a probe identification module disposed in the connector pod, the probe identification module having a cross-sectional area; and a resistor disposed in the connector pod, and in-line with the probe identification module and having a substantially identical cross-sectional area as the probe identification module.

Oscilloscope probe identification

A protocol analyzer for a test system has a control system coupled to a first interface and a second interface. The first interface receives a packet from a packet network. The control system receives the packet from the first interface and either deletes the packet or transfers the packet to the second interface based on a destination address in the packet. The second interface transfers the packet to another protocol analyzer. The destination address could be a MAC address.

Address routing in a protocol analyzer

A method and a system to synchronize a time of day clock of a clock system. The method and system include a portable satellite timing system at a first location receiving a satellite signal comprising a first time of day signal. An internal clock of the portable satellite timing system is calibrated based on the first time of day signal to generate a second time of day signal. The portable satellite timing system is transported to a second location and coupled to the clock system. The second time of day signal is transferred from the portable satellite timing system to the clock system and the time of day clock is synchronized based on the second time of day signal. After a time period, the portable satellite timing system is transported to the first location.

Method and system for synchronizing a time of day clock based on a satellite signal

A method for synchronizing a time of day clock of a clock system is disclosed. A portable satellite timing system receives a satellite signal when at a first location and generates a time of day signal. The portable satellite timing system is then transported to a second location, where the satellite signal cannot be reliably received, and coupled to the clock system. The portable satellite timing system transfers the time of day signal to the clock system. Concurrently, the clock system receives a communication signal from a communication system and recovers a clock signal from a communication signal. The clock system synchronizes the time of day clock based on the time of day signal and the clock signal. The disclosed method advantageously synchronizes the time of day clock located in a structure without having to install a satellite antenna on the outside of the structure.
