摘要： An example system includes input circuitry configured to obtain first data corresponding to first signals on a communication channel, with the first data having a first frequency that is less than a predefined frequency; and sampling circuitry configured to sample the first data to produce second data having a second frequency that is greater than or equal to the predefined frequency. The example system also includes switching circuitry configured to support AC-coupled data having a frequency that is greater than or equal to the predefined frequency, with the switching circuitry being configured to receive the second data and to forward the second data; and output circuitry to receive the second data and parametric data representing non-information signal content, to produce third data based on the second data, and to produce, based on the third data and the parametric data, second signals for output from the system.

摘要： An example system includes circuitry to receive an input signal, to provide a related signal based on informational content of the input signal, and to obtain parametric data associated with the input signal. The parametric data represents one or more signal characteristics other than the informational content. The example system also includes a first switch that is configurable to provide first data based on the related signal to one or more first channels of the system; and a second switch that is configurable to provide second data based on the parametric data to one or more second channels of the system.

摘要： An example test system includes a bus interface to connect to a bus of a computer system; and test instruments to perform one or more test operations on a UUT, where the test instruments connect to the bus interface to enable communication between the computer system and the test instruments via the bus interface. At least one test instrument includes: ports to which the UUT is connectable, with each of the ports interfacing to a corresponding peripheral bus supported by the at least one test instrument; circuits to connect the bus interface to the peripheral buses, with each circuit being configured to convert between a bus interface protocol run on the bus interface and a peripheral bus protocol run on a peripheral bus; and a switch to identify a target circuit of the circuits, with the switch to direct communications between the computer system and the target circuit.

摘要： Example pin electronics includes driver circuitry to output a first optical signal to a UUT. The first optical signal is based on a first signal representing first informational content and one or more second signal representing first parametric information. Receiver circuitry receives a second optical signal from the UUT. The second optical signal is related to a third signal representing second informational content and one or more fourth signal representing second parametric information. Comparison circuitry obtains parametric data representing at least one of the first parametric information or the second parametric information, and compares, based on the parametric data, the at least one of the first parametric information or the second parametric information to one or more thresholds. Control circuitry adjusts at least some of the first parametric information prior to output of the first optical signal, and one or more of the thresholds.
