Synchronizing Multiple Clipx Cf Amplifiers - HBM ClipX Bedienungsanleitung

6.11

Synchronizing multiple ClipX CF amplifiers

You should synchronize multiple ClipX devices that supply sensors with carrier fre-
quency (CF) so that the carrier frequency measuring amplifiers do not interfere with
each other. This will prevent crosstalk between adjacent sensor cables, resulting in dis-
turbance to measurements. If you are using only sensors with direct voltage (DC) ampli-
fiers, no synchronization is necessary.
To synchronize, interconnect the Sync terminals of the devices and the ClipX bus GND
terminals, unless you have already connected the latter to transmit measured values.
Lay the lines from the first device to the second, from the second to the third device, etc.
(line topology). The cable must have twisted-pair wires, and be shielded. The ClipX bus
GND and Sync lines must be twisted and shielded.
