Measure loudspeaker impedance
at any power level from milliWatts to kiloWatts!
Precision measurement of loudspeaker
impedance has always presented a unique set of problems. While the
commonly used constant current source (CCS) method provides easy
and quick impedance measurement, it sacrifices the quality and accuracy
of the data.
Loudspeakers are normally
operated in a constant voltage source (CVS) mode, by direct connection
to a power amplifier. For accurate impedance measurements CVS operation
must be maintained during impedance measurement as well.
