ParBERT 81250 Measurement Software
ParBERT Measurement
software consists of six
different measurements
that deliver graphical and
numerical results allowing in-
depth characterization
for use in R&D and Device
Verification (DV). Fast pass/
fail tests against user definable
limits for manufacturing
purposes are provided as well.
ParBERT, as any other BERT,
physically can only do one
measurement: it digitizes the
input signal with respect to a
predefined threshold voltage
and, at a predefined portion of
the bit width (the sample point),
compares this to its expected
data and counts an error if it
doesn’t match the expected
binary value.
ParBERT Measurement Software
automates the variation of these
mentioned parameters (sample
point timing and threshold
voltage) and the repetition of this
measurement for a number of
subsequent bits and by this
allows performing a variety of
measurements:
1. BER measurement,
targeting the error
performance of a complete
system under test
2. DUT output level
measurement
3. Eye opening
4. DUT output timing
measurement
5. Spectral decomposition
of jitter
allowing in depth pin- and
port-wise characterization of
the output performance of a
transmitter (TX) under test
as it is typically required in
R&D or during DV. Graphical
representation(s) of the test
result (e.g., pseudo color
plot and contour plots) are
available as well as a multitude
of extracted or extrapolated
numerical values. Pass/fail
criteria can be defined for
every numerical result,
simplifying a fast test against
limits making it well suited
for manufacturing as well.
Reduction of test time as it is
usually desired in manufacturing
is possible using the
6. Fast eye mask measurement
that requires a much smaller
number of measured bits.
Each of the six measurements is
an active-X component, which
simplifies its integration into any
test executive written with
Agilent VEE Pro, National
Instruments’ LabVIEW, Excel,
Agilent TestExec, C/C++, C#
and Microsoft^® VisualBasic.
The MUI comprises a Windows
(2000, XP or Vista) based GUI
that simplifies test set-up and
execution. Measurement results
can be exported and printed.
The measurement software is
included in the standard
ParBERT 81250 software
package. It works as a client to the
ParBERT firmware server and
can run on that PC that hosts the
firmware server and is connected
to the HW through the slot -0
controller, or on any other PC
that is connected (e.g. via LAN)
to this mentioned PC.
