Minimum network for measurement of noise immunity and noise emission of active
transceivers
• DPI tests, transients tests and EMI tests on a minimum network consisting of
three active transceivers
• ESD tests for the destruction of a transceiver with no power supply
Minimum Network for DPI Tests, Transients Tests and Emission Tests
Figure
2.39
depicts an overview of the minimum network for tests on an active
transceiver. The network consists of three CAN nodes. Each of the node circuitries
are identical, consisting of the transceiver which is to be evaluated, its minimum
circuitry according to the data sheet, the bus filter and a decoupling circuitry which
connects the signal for stimulation and control of the functions. The required volt-
age supplies (VBAT and VCC) are connected to the test network through well-spec-
ified filters. Noise injection and noise observation are performed through specific
coupling networks, which are compliant to the requirements of the individual IC
measurement method (see Table
2.3
).
