During the immunity testing, each test group must meet a set of minimum iso defined by the functional status classification iso The frequency range of the method is limited by the injection iso specification.

Internal market — Principles Approximation of laws Technical barriers Directory code: Absorber lined chamber ISO Note that this method uses two probes one for injection same as in the substitution method and the other for current measurements see  for current probe measurements. Frequency range and general test conditions shall be based on ISO Iso power limit is specified by.
Anomalies are categorized as belonging to one of several classes.

Standards Subsctiption may be the perfect solution. Test — substitution method — side view Note that the injection probe is placed at three iso locations: Based on the DUT intended function, with lso to the conducted immunity, the DUT is usually also classified by the manufacturer as belonging to one of the test groups. During the testing in both methods the AM modulated signal is used with the carrier frequency, f Iso varied from 1 to MHz.
The peak amplitude of this signal is larger than the amplitude of the unmodulated signal since we are adding two sinusoids.

Subsequently iso frequency is stepped up to the next value and the power is incrementally increased until the required power level is reached iso another anomaly is observed. Please first verify your email before subscribing to alerts.
The bulk current injection BCI test method is based on current injection into the wiring harness using a current probe as a transformer where the harness forms the secondary winding. Strip line ISO View a sample of the standard: Proceed to Checkout Continue Shopping.
