EMC32-S: Immunity level as a function of frequency

Question:

In my case, the target level of my susceptibility measurement is not constant.

Is it possible to configure the EMC32 with a falling or rising target level?

Answer:

Yes, you can configure this in the EMS Scan template. The lower section of the EMS Scan template editor contains a tab structure with four tabs where the parameters for each subrange are configured.

Go to the Level tab. Here, you can define the target test level either as a constant value for the whole subrange or as an immunity shape table.

EMC32-S: Immunity level as a function of frequency

If you have a falling or rising target level, then select Immunity Shape Table instead of Constant Immunity Table.

The immunity shape table defines the immunity level as a function of frequency. The table must have been generated previously as a limit line file. You can use the

EMC32 limit line editor to define your frequency-dependent target level according to your needs.
