Informationen:
                                    The LFM-39A Wow & Flutter Meter is a direct reading type
instrument designed for measurement of Wow, Flutter and
Drift characteristics of tape recorders, recordplayers and
other playback/recording equipment. The effective values,
peak-to-peak values and center frequency (3kHz or 3.15kHz)
of Wow & Flutter are indicated on the meter in accordance
with J1S, CC1R, DIN, and weighted specifications.
Five full scale ranges, 0.03%, 0.1%, 0.3%, 1% and 3%, are
used. The use of 0.03% range makes it possible to measure
accurately the Wow & Flutter characteristics of high-grade
tape recorders.
The LFM-39A contains an oscillator with excellent frequency
accuracy, which can be used to calibrate the drift meter and
supply a recording signal.
Moreover, this Wow &c Flutter meter is equipped with a TO
SCOPE terminal for analyzing Wow & Flutter components and a
RECORDER terminal for Wow & Flutter recording.
