Abstract
An example test system includes a test head, and a device interface board (DIB) configured to connect to the test head. The DIB is for holding devices under test (DUTs). The DIB includes electrical conductors for transmitting electrical signals between the DUTs and the test head. Servers are programmed to function as test instruments. The servers are external to, and remote from, the test head and are configured to communicate signals over fiber optic cables with the test head. The signals include serial signals.
Claims31
A test system comprising:
- a test head;
- a device interface board (DIB) configured to connect to the test head, the DIB for holding devices under test (DUTs) and the DIB comprising electrical conductors for transmitting electrical signals between the DUTs and the test head;
- and
- servers programmed to function as test instruments, the servers being external to, and remote from, the test head and being configured to communicate signals over fiber optic cables with the test head, the signals comprising serial signals.
1 more element
A test system comprising:
- a test head comprising first circuitry to condition an electrical signal that is an expression of an optical signal, the optical signal being from fiber optic cable and the electrical signal being for a device under test;
- the fiber optic cable over which the optical signal is passed;
- and
- a server programmed to function as a test instrument, the server being external to, and remote from, the test head, the server being configured to communicate over the fiber optic cable;
- wherein the electrical signal and the optical signal comprise serial signals.
2 more elements
A test system comprising:
- means for connecting electrically and mechanically to devices under test (DUTs);
- means for conditioning electrical signals obtained by conversion from optical signals;
- and
- means for generating test vectors that are converted to optical signals for transmission over fiber optic cable, the means for generating comprising one or more general-purpose servers that are remote from a point of connection to the DUTs.
