HSSL (digital; bandwith up to 25 MHz and 8-48 bit resolution): attocube's proprietary serial word protocol provides
1absolute
0 position information - both in terms of the protocol and the measurement itself. The HSSL interface consists of one data and one clock signal (single ended or differential); position information is packed into one container
of user-defineable bit-length, synchronization with the receiver is accomplished using the clock signal. The HSSL protocol
is preferential if absolute displacement position data (i.e. sensor-target separation) is required or if incremental position
counting
1
0 is inacceptable.
AquadB (digital; bandwith up to 25 MHz; resolution freely assignable): The AquadB interface provides incremental
displacement information on target displacement. Position resolution and (maximum) clock rate can be user defined using the software interface. For maximum data bandwidth, the AquadB interface is best used with differential signaling.
