Sign Wave vs. Full Bandwidth Pink Noise testing (1 reply)
I assume you mean a sweep or warble tone. These techniques are not necessarily faster given that each measurement requires a sweep but for an automated measurement may be easier to program and analyze.
Steady state pink noise provides a continuous stream of data, facilitates real-time spatial averaging, and can fully energize modal response. There are many arguments about all of these issues, but pink noise lends itself better to a calibrator investigating and hand calibrating a system.
