DUAL MEASUREMENT

ACV
Hz
 Measure the frequency response of
devices such as amplifiers or
buffers*.
* The frequencies of the amplifier
output must be within the DMM’s
measurable AC bandwidth for the
amplitude at a spot frequency to be
measured accurately.

Note
[1] 2W/4W measurements in combination with other
measurements are possible but may not be practical as
the measurement accuracy is not guaranteed.
[2] When two different measurements are taken, there is a
switching delay between the first measurement and the
second measurement.
