I3031-14.0 HBM: public 29
It is possible to achieve accuracies of 1 ms or higher,
depending on the utilization of the network and on
whether or not a dedicated NTP master is being used.
Modules located close together should be synchronized
via IEEE1394b FireWire.
If the synchronization source for a module is changed to
NTP, the system must be restarted once. The HBM cat
man®EASY software includes an NTP software pack
age.
Parameter:
S IP address of the NTP server
S Threshold in s below which the time deviation to
NTP time is tolerated
Further information about NTP can be found at

Synchronization via IRIG-B
IRIG-B is a standardized time coding.
To time-synchronize the QuantumX system, the digital or
analog modulated time signal is sent externally to any
analog voltage input of the amplifier type MX840B or
MX440B (see Assignment, section 8.2.1).
The B127 format uses analog modulation. Connection is
identical to that of a 10-V voltage sensor.
The other formats are BCD‐coded and must be con
nected analog to the sensor "Frequencies single-pole,
without directional signal", see section 9.29.
The amplifiers can record IRIG‐B signals of type B000 to
B007 and B120 to B127. All modules connected via
IEEE1394b FireWire are also automatically synchro
