circuits for generating HV pulses in dielectric strength testing G01R31/14)} - G01R 31/002: {where the device under test is an electronic circuit} - G01R 31/327: Testing of circuit interrupters, switches or circuit-breakers - G01R: MEASURING ELECTRIC VARIABLES; MEASURING MAGNETIC VARIABLES (indicating correct tuning of resonant circuits H03J3/12) ## Abstract Disclosed is an apparatus for testing a device, comprising: a switch (100) arranged to replace a circuit breaker (30) associated with an individual system in the device under test, wherein the switch (100) is operable to be controlled remotely from the device under test such that the switch (100) either activates or deactivates the individual system. ## Claims ### Claim 1 An apparatus for testing a platform under test, the apparatus comprising: a test device comprising: a switch arranged to temporarily replace a circuit breaker configured to complete a power circuit of an individual system in the platform under test, wherein the switch is configured to be controlled remotely from the platform under test such that the switch either completes or interrupts the power circuit of the individual system; and a controller configured to generate a control signal to operate the switch; and a battery that is not a component of the system in the platform under test, the controller being powered by the battery, no element of the platform under test receiving power from the battery. ### Claim 2 (depends on 1) The apparatus according to claim 1 further comprising a test chamber for containing the platform under test. ### Claim 3 (depends on 1) The apparatus of claim 1 wherein the apparatus further comprises a suitably programmed computer and the controller is connectable to and further controllable by the computer. ### Claim 4 (depends on 3) The apparatus of claim 3 wherein the computer is connectable to the controller by a wired data connection. ### Claim 5 (depends on 3) The apparatus of claim 3 wherein the computer is connectable to the controller by a wireless data connection. ### Claim 6 (depends on 3) The apparatus of claim 3, wherein the computer is external to the test chamber. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the switch is included in a plurality of switches, each of the switches being operable to activate or deactivate a particular individual system. ### Claim 8 A method of testing a platform under test, the method comprising: providing a test device comprising a remotely operable switch, a controller configured to generate a control signal to operate the remotely operable switch, and a battery that is not a component of the platform under test, the controller being powered by the battery; temporarily replacing a circuit breaker operable to provide power to complete a power circuit of a particular system in the platform with the remotely operable switch by disconnecting the circuit breaker from the particular system in the platform and connecting the switch to the particular system in the platform in place of the circuit breaker, so that the remotely operable switch is able to provide power to complete the power circuit of the particular system in the platform, and so that no element of the platform under test receives power from the battery; operating the remotely operable switch to provide power to, or remove power from, the particular system in the platform as required; performing a test; and disconnecting the switch from the particular system in the platform and reconnecting the circuit breaker to the particular system in the platform, thereby restoring the circuit breaker to being operable to provide power to the particular system in the platform, the switch, controller, and battery being thereby isolated from interacting with the platform under test. ### Claim 9 (depends on 8) The method of claim 8 wherein there is provided a test chamber for containing the platform under test, the remotely operable switch being operable from outside of the test chamber. ### Claim 10 (depends on 9) The method of claim 9 wherein the test chamber is an RF anechoic chamber. ### Claim 11 (depends on 9) The method of claim 9, wherein the platform under test is suspended off the ground of the test chamber. ### Claim 12 (depends on 8) The method of claim 8, wherein the method is carried out in an RF test environment such that performing the test comprises illuminating the platform under test with high power RF radiation. ### Claim 13 (depends on 8) The method of claim 8, wherein the platform under test is a vehicle.
