General Queries

Q: What is the WiMedia Explorer 300 Analyzer?
A: The WiMedia Explorer 300 Analyzer is a protocol analyzer capable of analyzing both WiMedia's Ultrawideband and Wireless USB protocols. It brings many great features to early prototypes development, wireless communication optimization and other hardware and software development tasks. The WiMedia Explorer 300 Analyzer records traffic exchanged over the air between devices and displays the resulting decoded information in a convenient way.

Q: What is the WiMedia Explorer 300 Generator?
A: The WiMedia Explorer 300 Generator is a byte-level frame generator for WiMedia Ultrawideband and Wireless USB protocols. It helps verify product and component reliability by generating reproducible traffic, timing and error scenarios.

Q: What is the recommended configuration to use the WiMedia Explorer 300?
A: The WiMedia Explorer 300 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 control computer to ensure proper operation.

Q: What is the maximum amount of data that I can record with the Analyzer?
A: The analyzer uses the hard disk to store analyzed data. The maximum quantity of data is therefore limited by the capacity of the control computer's hard disk.

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 WEX300GENLIC). 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 check the Duo on the WiMedia Explorer 300 Purchase Page for more information.

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 check the Wired Ultrawideband Kit Option on the WiMedia Explorer 300 Purchase Page for more information.

Analyzer Software

Q: I would like to filter out certain undesirable information. What do I need to do?
A: Contextual filters appear when the software detects redundant information that can be safely filtered out. These filters are the most convenient and simple to use.

Instant filters enable more powerful filtering. A text zone for each column is provided for this. Simply enter 2,3 in the Device column to display peripherals 2 and 3 only. In the same way, entering !0,1 in the Endpoint column conceals all the endpoints except 0 and 1. Numeric columns also accept ranges. Typing 1..10 in the Time column will keep only items that took place between the first and the tenth second of analysis.

Q: The detailed view enables me to see high-level textual information. What do I need to do to see numeric low-level information?
A: Low-level information (decimal, hexadecimal and binary data) is available by clicking on the buttons Hex, Dec and Bin located at top of the view. The Raw data panel can also be used to see data in hexadecimal, decimal, binary or ascii representation.

Q: The software shows decoded data in the Details view but it seems that some fields are missing. Where are they?
A: The software hides fields that are irrelevant by default. You can display them by clicking on the button. Additional fields will appear in a slightly lighter color.

Geneartor Software

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 checking the trace recorded with the protocol analyzer.


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 analyzer'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 analysis hardware module is plugged into the analyzer's main board and can be replaced with future modules supporting new features like international compliance, higher data rates and new services.

Q: Is it possible to upgrade the firmware?
A: Yes, the hardware of the WiMedia Explorer 300 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.

Q: I saw on the specifications that the analyzer memory is 1GB of FIFO. What does it mean?
A: The memory contained in the analyzer is a dual port FIFO memory. This kind of memory enables read and write operations at the same time, allowing to record analyzed data and download it to the analysis computer at the same time. This way it is possible to record much more memory than available in the analyzer, and it is also possible to see the analyzed data immediatly instead of waiting until the end of the recording session.
