DIGITAL DISTORTION METER :
|
SIGMA DISTORTION METER DSM-201 is meant for measuring the harmonic distortion of any signal. It may be caused due to non-linearity of characteristics of an Amplifier, or any type of electronic circuit or may be noise generated in the circuit.
The DISTORTION METER DSM-201 a highly selective balancing network is used to eliminate the fundamental frequency in the 20Hz to 20kHz band. The distortion products are fed to a stable high-gain wideband amplifier for indication on the meter. The amplifier is effective up to 200KHz and measurements are possible up to and including the tenth harmonic of 20KHz.
