摘要： Determining ambient noise in a device under test electromagnetic compatibility test environment is presented herein. A method can include determining, by a system comprising a processor via a radio frequency input port of the system, an ambient electromagnetic noise corresponding to the system; and in response to determining, by the system via the radio frequency input port, a radio frequency signature of a device under test, subtracting, by the system, the ambient electromagnetic noise from the radio frequency signature to obtain a normalized value representing an electromagnetic emission of the device under test. In an example, an antenna/coaxial cable has been connected to the radio frequency input port, the ambient electromagnetic noise can be determined using the antenna/coaxial cable, and a radiated/conducted electromagnetic characteristic of the device under test representing the radio frequency signature of the device under test can be determined using the antenna/coaxial cable.

摘要： Each of a plurality electronic circuit devices fixed to a structural component of a physical structure can be scanned a first time, using a radio frequency (RF) scanner to receive, from each of the plurality of electronic circuit devices, first data indicating a first measured electrical impedance of a respective conductor connected to the electronic circuit device and an identifier assigned to the electronic circuit device. For each of the plurality of electronic circuit devices, the first data indicating the first measured electrical impedance and the identifier assigned to the electronic circuit device can be stored to a first memory. The first data indicating the first measured electrical impedance and the identifier for each of the electronic devices can form a baseline measurement of the electronic circuit devices.

摘要： A method of protecting devices within an integrated circuit during electro-static discharge (ESD) testing using an ESD test system is provided. The method includes applying a direct current (DC) bias voltage to an input of at least one device of the integrated circuit and applying an ESD simulated signal to at least one other input of the integrated circuit. The applied ESD simulated signal is conducted along a first current path to a first ground, while a low-current signal associated with the at least one device is conducted along a second current path to the second ground. The DC bias voltage is maintained between the input of the at least one device and the second ground at a substantially constant value in response to a signal variation on the second ground that results from the applied ESD simulated signal.

摘要： A method of testing a semiconductor device against electrostatic discharge includes operating the semiconductor device, and, while operating the semiconductor device, monitoring a functional performance of the semiconductor device. The monitoring includes monitoring one or more signal waveforms of respective one or more signals on respective one or more pins of the semiconductor device to obtain one or more monitor waveforms, and monitoring one or more register values of one or more registers of the semiconductor device to obtain one or more monitor register values as function of time. The method includes applying an electrostatic discharge event to the semiconductor device while monitoring the functional performance of the semiconductor device. The method can further comprise determining a functional change from the one or more monitor waveforms and the one or more monitor register values as function of time.

摘要： An EMI testing deviation correction system includes an EMI testing facility. A signal provisioning device in the EMI testing facility includes a power connector coupling coupled to a networking port. A signal generator includes a power connector that is connected to the power connector coupling, and generates and provides signals having first signal characteristics through the power connector. An ISN device is coupled to the first networking port to receive signals that are provided by the signal generator and transmitted through the signal provisioning device. A signal receiver device is coupled to the ISN device and receives signals transmitted through the signal provisioning device and the ISN device. The signals received by the signal receiver device include second signal characteristics, and the difference between the second signal characteristics and the first signal characteristics provides an indication of at least one correction for the EMI testing facility.
