The SVV/SVM Sine-Cosine converter takes the quadrature, differential, output signals from a suitably matched SHG-VV/VM or MHGVV/VM encoder and converts these signals to analogue sine and cosine levels.
The SVV module provides 1V p-p and the SVM module provides 11mA p-p standards. Both provide differential signals and a 'digital' reference marker signal as shown below.
