g) If the DUT is of component categories AX, AY and EM, measure and record the peak transient voltages while

exercising the DUT functions in operating modes identified in the EMC test plan. This step may be omitted for

component categories BM and R.

h) For all component categories with switched power circuits, measure and record peak positive transient voltages

exceeding the trigger level while by turning the DUT off and on ten times (10 measurements for each condition) via

the external switch shown in Figure 10-1.

i) Repeat step e) through h) for each of the following time base values:

• 100 usec/div;

• 1 usec/div

• 0.5 usec/div

Alternative time base values may be selected if those listed are not available for the oscilloscope used. The lab shall

use the closest time base value available. The time bases used shall be documented in the EMC test report.

j) Re-adjust the trigger level of the digital sampling scope to -60 volts. Repeat steps e) through i) except record the peak

negative transient voltages exceeding the trigger level.

Design Note

Although CI 410 requirements are validated at room temperature, the product should be designed to meet the

same requirements at -45 degrees C or the coldest ambient temperature specified in the product's engineering

specification
