This page answers the questions that our technical team is asked most often. It also features a few hints and practical tips in the question and answer mode.
| Q: |
What
is the WiMedia Explorer 300 Generator? |
| A: |
The WiMedia Explorer 300 Generator is a byte-level frame generator for WiMedia Ultrawideband
and Certified Wireless USB protocols. It helps verify product and component
reliability by generating reproducible traffic, timing and error scenarios. |
| Q: |
The
WiMedia Explorer 300 Generator box is very similar to the WiMedia Explorer 300 Analyzer.
Does these products share some similarities? |
| A: |
The WiMedia Explorer 300 Generator is based on the same proven hardware as the Ellisys WiMedia Explorer 300 Analyzer. The software and the programmable
logic of these products are though very different. |
| Q: |
I
have a WiMedia Explorer 300 Analyzer. Can it be upgraded to add the generation
functionality? |
| A: |
Yes. The generation functionality is available as an option of the WiMedia Explorer 300 Analyzer (the product code is UWBGENLIC). With this option, an unit
can be used either as protocol analyzer or generator, but not at the same time.
We offer special deals to customers buying a protocol analyzer along with a
generator. Please contact the Ellisys sales
team for more information about this. |
| Q: |
The
WiMedia specifications may change to support international compliance,
higher data rates or new services. Will I need to purchase a new equipment
each time the specification changes? |
| A: |
The modular generator's hardware architecture is engineered to be upgradeable
as the specifications evolve. The main board hardware is fully programmable
and can effortlessly accommodate specifications evolutions. The Ultrawideband
radio hardware module is plugged into the generator's main board and can
be replaced with future modules supporting new features like international
compliance, higher data rates and new services. |
| Q: |
I have been told that Ultrawideband has not yet been regulated in my country. Can I start developing UWB devices without causing unauthorized interferences? |
| A: |
Wireless information is transmitted over the air between devices through
electromagnetic fields. These fields must stay within certain limits that have
already been defined and accepted in the USA but regulations are still in progress
in many other countries. Ellisys suggests a configuration to connect the system
under test with high frequency cables. Please contact the Ellisys
sales team for more information about this solution. |
| Q: |
I
saw a suspect behavior of my device with my Ellisys' analyzer,
but I am unable to reproduce the same conditions to verify if the error
is fixed. Can the generator helps? |
| A: |
Traces recorded with the Ellisys WiMedia Explorer 300 Analyzer can be exported
from the analysis software to the generator. If your trace contains enough
information, you will be able to reproduce the problem using the generator,
and verify that you fixed the the issue by using the protocol analyzer
in conjunction. |
| Q: |
What
is the recommended configuration to use the generator? |
| A: |
The generator connects on a USB 2.0 port, allowing
the use of any compatible notebook or desktop computer. The unit is powered
by USB and does not require an external adapter. A driver will be installed
on the computer to ensure proper operation. |
| Q: |
The
analyzer supports recording data using a USB 2.0
connection. Do I need a USB 2.0 host controller? |
| A: |
No. The generator works just as well with a High speed connection (480
Mbit/s) as with a Full speed connection (12 Mbit/s). However, we recommend
using a High speed connection to reduce the time needed to upload script data. |
| Q: |
Is
it possible to upgrade the generator firmware? |
| A: |
Yes, the hardware of the generator is upgradeable. The electronic components
are automatically updated with each new software release. No user intervention
is therefore required. We send a newsletter to our subscribers when a new
release of the software is available. |
