The Distortion Analysis Option provides software required for
the DSP analyzer to measure total harmonic distortion (THD) from
0.02% to 9.99%. An external signal generator such as Gold Line's
Model TS1 or TS2 is required to input a test tone to the system
under test. The analyzer will show the primary test frequency
and resulting harmonics with the total harmonic distortion shown
as a numeric value. No computer is needed with this option.
Option Kit Contains: An upgraded EPROM device and a
jumper cable to internally connect the circuit board to the
front panel.
