Master/Slave Board; Fiber-Optic Cable - HBM GEN Series User Manual

Master/Slave board

The Master/Slave board synchronizes clocks, triggering and start signals between all connected
mainframes. Connections are made using fiber-optic cables. The Master/Slave option allows
for a Multi-Mainframe configuration to work as a single unit. Within a combination of mainframes,
one mainframe is used as a master that can drive up to eight slaves.
Master/Slave board operating modes
The Master/Slave board has three operating modes:
Master
l
Slave
l
Stand-alone
l
In Master mode:
all connectors function as master output
l
the start of recording as well as synchronization signals are transmitted to all connected
l
slaves
all trigger signals are combined into a global master/slave trigger signal
l
In Slave mode:
the top connector is configured as slave input, all other connectors are unused
l
all received signals are transferred to a bus for internal distribution
l
internal slave trigger signals are transferred to the outside
l
In Stand-alone mode:
Stand-alone mode is OFF: the Master/Slave board does not communicate with other
l
Master/Slave boards.

Fiber-optic cable

The Master/Slave board has optical I/O (IN/OUT) that connects to other Master/Slave boards.
The fiber-optic cable:
allows up to a 300 m cable between the master and each slave
l
distributes the sampling clock, absolute time info, trigger and start/stop signals between
l
mainframes, creating a real high channel synchronized system out of the nine mainframes
enables a timing accuracy between the mainframes less than 100 ns
