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.
