This unit has an ultra-low distortion sine wave generator, a high performance THD measuring system, and a wide range & high sensitivity signal level and noise measuring facility. In addition, a tuneable band pass filter allows the unit to operate as a selective voltmeter or for manual spectrum analysis. The filter may also be configured as a low pass filter for band limited noise measurements. The instrument also incorporates a comprehensive set of user modifiable filters for noise measurements to various standards.
