1. A test instrument comprising:
- a processing system programmed to control operation of the test instrument, including communication with a control system, and programmed to run one or more test programs to test a device interfaced to the test instrument, the processing system comprising multiple processing devices, the processing system comprising a first processing system and a second processing system, with the second processing system being between the device interfaced to the test instrument and the first processing system; and
programmable logic between the second processing system and the device interfaced to the test instrument, the programmable logic comprising a configurable interface, through which communications are exchanged with the device interfaced to the test instrument, the configurable interface comprising physical ports, to which different configurations are assignable based on whether the first processing system or the second processing system is executing a test program to test the device interfaced to the test instrument, the different configurations being assignable in real-time during execution of the test program;
wherein the first processing system, the second processing system, and the programmable logic are each configured to perform testing on the device interfaced to the test instrument, with the second processing system having less test latency than the first processing system, and the programmable logic having less test latency than the first processing system and the second processing system.

11. A method comprising:
-
configuring a processing system comprised of multiple processing devices to control operation of a test instrument, including communication with a control system, the configuring comprising programming the processing system to run one or more test programs to test a device interfaced to the test instrument, the processing system comprising a first processing system and a second processing system, with the second processing system being between the first processing system and the device interfaced to the test instrument; and configuring a configurable interface implemented in programmable hardware, through which communications are exchanged with the device interfaced to the test instrument, the configurable interface comprising physical ports, to which different configurations are assignable based on whether the first processing system or the second processing system is executing a test program to test the device interfaced to the test instrument, the different configurations being assignable in real-time during execution of the test program; wherein the first processing system, the second processing system, and the programmable hardware are each configured to perform testing on the device interfaced to the test instrument, with the second processing system having less test latency than the first processing system, and the programmable hardware having less test latency than the first processing system and the second processing system. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
