Phase Shifters in the PWM-84C series provide a minimum of 360° phase shift in 8 binary increments (255 steps) of approximately 1.4° each. Phase shift is produced using a series of frequency independent analog phase shifters which are driven by an 8-bit D/A converter. This method, unlike conventional switched cable designs is guaranteed to be monotonic even at higher frequencies. 2. The monotonic feature of this design is advantageous when used for control applications in closed loop systems.
