Note Before changing or removing input cards, always check your warranty
information. Changing input cards will void the tight calibration of the input card.
Wider tolerance have to be considered when exchanging input cards. See

Master/Slave Card

The GEN series can be operated as a fully synchronized Multi-Mainframe
system with multiple mainframes using the Master/Slave card.
With the Master/Slave card you can:
connect one GEN series "Master" to up to eight "Slaves"
l
fully synchronize up to nine mainframes
l
record up to 1080 channels with 1 MS/s sampling speed each by using all
l
slots
or record up to 540 channels with 100 MS/s per channel by using all slots
l
use the fiber optic link with up to a 500 m cable between the master and
l
each slave
And the Master/Slave option provides:
the sampling clock, absolute time info, trigger and start/stop signals be-
l
tween the mainframes, creating a real high channel synchronized system
out of the nine mainframes
a timing accuracy between the mainframes better than 100 ns
l
an automatic cable length detection and compensation
l
For information on the usage of the master/slave card, see "Master/Slave Card"
on page 212.

Thermal protection

Every GEN series mainframe supports a feature called Thermal Shutdown. For
this the mainframe and acquisition cards have build-in digital thermocouples to
measure local temperatures. The GEN series embedded software reads these
values every minute and monitors the system internal temperature for
overheating.
