Virtual Instruments™ Signal Integrity (VISI) Software delivers
a comprehensive set of jitter analysis tools in a remarkably
easy-to-use interface that helps simplify timing, jitter and
signal integrity characterizations. The software offers a flexible
platform for all your test and measurement needs. Choose from
one of our software modules to analyze jitter in clock, DRCG,
datacom and databus applications. |
As of November 2003, the current version of
VISI software is 6.31 for DTS products and 7.4 for SIA products.
|
|
|
|
VISI software gives test engineers, production managers and
technicians a simple, straightforward way to perform complex
jitter analysis—and generate clear, concise results that
help users optimize device performance faster than ever before.
|
|
Key Features include:
-
Automated setup and data analysis
-
Create customized macros
-
Recognize trends in record time
-
View multiple tools simultaneously
-
VISI software options are loaded directly into the SIA-3000.
DTS series products work with VISI loaded on a computer
connected via GPIB to the DTS
With VISI and one of the WAVECREST SIA-3000
family of signal integrity analyzers, you can:
- Perform complete jitter testing with one solution
- Use the Wizard utility to set up tools and tests automatically
- Use the Plot Interpreter for guided troubleshooting
- Identify trends by overlaying windows with different data
patterns
- Create macros to repeat common keystrokes easily
- Save special settings or an entire test session with one
keystrok

| Reasons to Upgrade from Previous Versions
of VISI Software |
VISI for SIA
|
VISI 7.2 to 7.4
|
|
Added Advanced PLL Analysis tool. The software tool
determines PLL parameters from 2nd order PLLs such as
the damping factor, natural frequency, lock range, lock-in
time, pull-in time, pull-out range, noise bandwidth
and power spectral density of the noise. Graphs showing
the PLL transfer function, poles and zeros and Bode
plot are also generated.
Improved oscilloscope GUI tool for new channel card
options. Oscilloscope tool now has automated calculations
for Rise Time, Fall Time, Overshoot, Undershoot, Vmax,
Vmid, Vmin, Vtop, Vbase, Vpk-pk, Vamp, VRMS, VAVG, Mask
Violations, Mask Comparisons, Horizontal and Vertical
histograms and statistics.
Increased throughput for measurements using the High
Frequency Modulation tool and Known Pattern with Marker
tool.
|
VISI 7.1 to VISI 7.2
|
| Added software support for PM50 pattern
marker option. The PM50 option enables the user to input
a data stream with a repeating pattern into an SIA-3000
channel card and obtain quantitative information on DJ,
RJ, PJ, DCD&ISI and their contribution to Total Jitter.
The PM50 option also has the capability to detect bit
errors in the pattern. The user can view the errors and
their location in the pattern. The ability to detect bit
errors provides additional information about low probability
errors, BER, and pattern dependent errors. Bit error counting
can be performed at distinct frequencies in pattern match
mode. |
| Added updates to
the plot interpreter so all tools have the most common
data set descriptions |
|
Added explorer tool for easy file transfer
|
| Added the capability to run VISI on any
PC and control the SIA-3000 |
| Added software support for gate mode and
external 10 MHz source |
VISI 7.0 to VISI 7.1
|
| Added multichannel support for Datacom,
Histogram and Stripchart tools |
| Added support for the OE-2 and
the DSM products
|
| Added new channel selection menu for one-step
channel selection |
| Added plot interpreter for a guide in understanding
data. Included a Wizard to guide the user in acquiring
data. Added calculator and Wordpad to toolbar and added
the ability to access updates to online documentation. |
| Added the ability to analyze DDR signals |
| Added first order low pass filter to High
Frequency Modulation tool in order to obtain RJ over a
user defined bandwidth |
| Added sparse Tail Fit option in Known Pattern
with Marker to improve throughput efficiency |
VISI 7.0
|
| Initial software release for the SIA-3000 |
|
VISI for DTS
|
VISI 6 to VISI 6.3
|
| Added
Auto-scale function to oscilloscope tool. |
|
Improved user channel selection menu. |
|
Improved Tail fit criteria selection to allow the user
to select the number of tail fits to be performed. |
| Updated
menu structure for ease of navigation. |
|
Support added for OE-2 product. |
VISI 5 to VISI 6
|
| VISI
5 had separate windows opening for each tool. In VISI
6 the tools are all inside one application. |
| Changing
view or plot preference in VISI 5 erased the acquired
data. VISI 6 acquires all data for all plots (for a tool)
and allows the user to toggle between views without reacquiring
measurements. |
| Measurements/data/plots
can be saved and recalled as a set of data in VISI 6.
This allows users to zoom, scale, add markers and turn
on filters all on stored results. In VISI 5, the only
"data" that could be saved were basic plot coordinates,
or a screen shot bitmap of the plot. |
| In
addition to recalling data, in VISI 6 similar plots can
be overlayed (so that data from a "golden part"
could be compared to a current measurement). |
| VISI
6 offers a greatly improved menu structure. Features are
logically located in appropriate topics for quick setup. |
| VISI
6 allows the user to put text (such as part number, lot
number, or notes) on plot or summary page. |
| In
VISI 6, macros allow the user to record keystroke sequences
(or program using VB scripts). |
VISI 3.2 to VISI 5
|
| Tail-fit
was added (separate random and deterministic jitter) |
| Datacom
as we know it today, did not exist in 3.2x. Known pattern
with marker was put into VISI 5 (improved algorithms) |
