analyzing digital signals as with any Agilent 81250 Parallel Bit Error
Ratio Tester.
For example, if you wish to stimulate a multipler device, you will have to
disconnect the generators from the MUX module.
To use a ParBERT 43/45G pattern generator or error detector system for
general purposes:
1 Disconnect all signal cables from the frontends.
It is strongly recommended to unscrew the cables from the
generator/analyzer modules and to leave the connectors at the
MUX/DEMUX module in place, because the cables have been
calibrated. If you disconnect both sides, you should label the cables so
that they can be re-installed for the same connections.
2 Remove the MUX/DEMUX module from the mainframe.
As long as the MUX/DEMUX module is installed, the software will not
allow you to access the channel parameters.
Take ESD precautions, e. g. wear a grounded wrist strap. These modules
are susceptible to electrostatic discharge.
3 After power on, run the Agilent 81250 Configuration tool and activate
the “ Build Systems ” function.
After that, you have a normal, general-purpose ParBERT system with 16
generator or analyzer channels that can be used for stimulating a
multiplexer or measuring the output of a demultiplexer device. You can
align the connectors, attach your test cables, and compensate for cable
and propagation delays.
