1Introduction
1.1 GEN series Multi-Mainframe configurations
our GEN series Data Acquisition System is one of the most sophisticated and powerful
systems in the marketplace and demonstrates the quality HBM has to offer. GEN DAQ
products are “future-proof”, modular and easily extendable.
Using the GEN series Master/Slave option, multiple mainframes can be interconnected to
provide a synchronized multi-mainframe test system with hundreds of channels. The Master/
Slave option for the GEN series Data Acquisition System enables up to nine mainframes to be
fully synchronized.
The new Master/Slave board for the GEN series extends the high channel count capabilities of
the GEN series by offering fully synchronized acquisitions between mainframes. The Master/
Slave boards establish a fiber-optic connection between mainframes, thus overcoming EMC
problems inherent in electrically based Master/Slave approaches.
With a Master/Slave connection, all mainframes run from the same clock and distribute real-
time information as well as triggers between mainframes. At the first connection between Master
and Slave, the Master figures out the distance to the Slave, computes the signal runtime and
compensates for skews caused by different cable lengths. Therefore, the GEN series can
support a distributed system with up to 300 m between sub-systems while still maintaining a
sample and trigger synchronous acquisition. So a large scale acquisition can be broken into
“sub-stations” which can be positioned as close to the device under test as possible to minimize
intrinsic noise caused by long cables.

2.1 Introduction
his chapter contains information about the Master/Slave option which is delivered with a
Master/Slave board and a fiber-optic cable. It describes how to install and connect the
Master/Slave board with the fiber-optic cable in the correct way and how to set the software
settings in the Perception software.
The chapter contains information about:
lMaster/Slave option
lDeliverables
lOptions
lMaster/Slave board
lInstallation
lConnecting the Master/Slave board
lExample of a Master/Slave configuration
lSetting the Master/Slave operating modes

lSetting the synchronization source
2.1.1 Master/Slave option
The GEN series can be operated as a fully synchronized Multi-Mainframe system with multiple
mainframes and Master/Slave option.
With the Master/Slave option you can:
lconnect one GEN series “Master” to up to eight “Slaves”
lfully synchronize up to nine mainframes
lrecord up to 1080 channels with 1 MS/s sampling speed each by using all slots
lor record up to 540 channels with 100 MS/s per channel by using all slots
luse the fiber-optic link with up to a 300 m cable between the master and each slave
And the Master/Slave option provides:
lthe sampling clock, absolute time info, trigger and start/stop signals between the
mainframes, creating a real high channel synchronized system out of the nine mainframes
la timing accuracy between the mainframes better than 100 ns
lan automatic cable length detection and compensation

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:
lMaster
lSlave
lStand-alone
In Master mode:
lall connectors function as master output
lthe start of recording as well as synchronization signals are transmitted to all connected
slaves
lall trigger signals are combined into a global master/slave trigger signal
In Slave mode:
lthe top connector is configured as slave input, all other connectors are unused
lall received signals are transferred to a bus for internal distribution
linternal slave trigger signals are transferred to the outside
In Stand-alone mode:
lStand-alone mode is OFF: the Master/Slave board does not communicate with other
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:
lallows up to a 300 m cable between the master and each slave
ldistributes the sampling clock, absolute time info, trigger and start/stop signals between
mainframes, creating a real high channel synchronized system out of the nine mainframes
lenables a timing accuracy between the mainframes less than 100 ns

2.2 Master/Slave board
The Master/Slave board is easily inserted into the GEN series mainframe and is automatically
recognized by the Perception software. A Master/Slave board can be used as a master or slave.
One board is required in the master mainframe and one board is required per slave mainframe.
Each board has eight LC® connectors for the fiber-optic cable.
Figure 2-1: Master/Slave board
In Master mode, all connectors M function as master output (OUT 1 to OUT 8).
In Slave mode, the top connector S functions as a slave input (IN), all other connectors are
unused.

2.2.1 Installation
Installing and removing the Master/Slave board
The Master/Slave board is easily inserted into the GEN series mainframe and is automatically
recognized by the Perception software.
The board is removed and installed in the same way as all the acquisition boards.
Note On the GEN series 19” rack model remove the acquisition board from slot A.
CAUTION
HBM uses state-of-the-art electronic components in its equipment. These electronic
components can be damaged by a discharge of static electricity (ESD). Therefore, we
must emphasize the importance of ESD preventions when removing or installing boards.
CAUTION
The GEN series Data Acquisition System is factory-calibrated as delivered to the
customer. Swapping, replacing or removing of boards may result in minor deviations to
the original calibration. The GEN series system should be tested and if necessary,
calibrated, at one-year intervals or after any major event that may affect calibration. When
in doubt, consult your local supplier.
LASER SAFETY
CLASS 1 LASER PRODUCT. Avoid exposure to laser radiation. Do not stare into an open
aperture, because invisible laser radiation may be emitted from the aperture when a cable
is not inserted in the connector port. The system is classified as a Class 1 laser product.
The Master/Slave board uses an LC® Optical Tranceiver for communication. It does not
emit hazardous light but it is recommended to avoid direct exposure to the beam.
The built-in laser complies with laser product standards set by government agencies for Class 1
laser products:
lIn the USA, the Master/Slave board is certified as a Class 1 laser product conforming to the
requirements contained in the Department of Health and Human Services (DHHS)
regulation CDRH 21 CFR, Chapter I Subchapter J Part 1040.10.
lOutside the USA, the Master/Slave board is certified as a Class 1 laser product conforming
to the requirements contained in IEC/EN 60825-1:1994+A1+A2 and IEC/EN 60825-2.
