2 Introduction ParBERT Components Overview

A generator or analyzer channel of a system is identified by
C lockgroupNumber – M oduleNumber – C onnectorNumber, for example,
C1 M3 C4.
Multiple ParBERT Systems
Separate systems are widely used for testing multiplexers or
demultiplexers. Such devices generally require different clock frequencies
at the generator and analyzer sides. Multiplexer/demultiplexer tests can
be performed by one system, if the ratio of these frequencies is 2
n
, such as
2, 4, 8, 16, and so on. If it is not, separate data generating and data
analyzing systems will do the job.
If you need systems with different timing requirements, you will install
independent clock modules, not connected in master-slave configuration.
Each clock module and its associated data modules are then
automatically treated as a separate ParBERT system (each starting with
clockgroup 1).
The first system (leftmost in the master mainframe) is automatically
called
DSRA (DSR = Digital Stimulus and Response, system A).
If the hardware comprises several independent clock modules, the 81250
ParBERT Configuration tool creates additional systems. By default, they
get ascending names, such as DSRB, DSRC, and so on. You can change
these names by editing the configuration file
dvtsys.txt
.
