Average detector

Posted on: December 16th, 2020 by James

The RIGOL DSA800 and DSA700 families have an RMS Average detector which is great for basic average measurements. However, the RMS Average detector differs from the Linear Average detectors associated with many EMI measurements.

This measurement can best be approximated by combining a video bandwidth filter of 10 Hz and using a linear amplitude scale mode. This test method is considered appropriate by the FCC.
