Phase Meter
SD1000
-
The SD1000 phase meter offers superb accuracy with a wide range of signal conditions. Conventional phase meters are easily upset when small levels of noise and distortion are present - the result is often unstable and incorrect phase readings. The SD1000 overcomes this by using Discrete Fourier Analysis (DFT), this process rejects any noise and distortion without the need for tracking filters.
