Creating Scan Tables with up to four detectors using EMC32

Question

I am using EMC32 for EMI Testing with various Test Receivers.

When creating a scan table, the software allows me to select up to max. two different detectors. For other Receivers I can select up to four detectors.

Is there a specific reason for this?

Answer

You are right. Depending on Test Receiver, EMC32 allows up to 4 detectors in parallel.

If you have three or four detectors, one of the detectors is usually a CISPR detector, which is much more time consuming.

Modern Test Receivers allow more than two detectors with different detector weighting simultaneously and they usually have a Time Domain Scan. Time Domain Scans reduce the required overall measurement times enormously by using FFT. It may even eliminate the need for prescans and data reduction (e.g. for some voltage tests), because scans with CISPR detectors are already fast enough.

Therefore, it is possible to configure EMI scans with up to four detectors for all Test Receivers that can provide a Time Domain Scan option.. This feature can be very useful.
