Wireless communication tester has China covered

Test software option supports the TD-SCDMA third generation mobile telecommunications system now being considered for commercialisation in China.

Yokogawa has added a test software option to its VC3300 wireless communication tester that supports the TD-SCDMA third generation (3G) mobile telecommunications system now being considered for commercialisation in China.

Shipment of this software option will commence at the end of December.

The VC3300 wireless communication tester tests mobile-phone basestation connections and wireless communication characteristics with high speed and high accuracy.

When test software supporting communication systems such as GSM and WCDMA are installed on the VC3300, it can test mobile phones that are based on both of these standards.

With installation of the newly developed TD-SCDMA test software option, the VC3300 can be used on production lines or at repair centres to test TD-SCDMA mobile phones.

Since the test function for this communication system is provided as a software option, no hardware modification is required.

WCDMA and other 3G wireless communications standards are rapidly entering commercial use, particularly in Japan, Europe and North America.

TD-SCDMA is one such standard, and it is being developed for use in China.

In preparation for the next year's Beijing Olympics, major cities around the country are planning to expand their test networks and start fully fledged commercial services.

TD-SCDMA mobile phones will also support GSM, which is a second-generation standard already used in China, and are planned to operate as dual-mode terminals.

In response to these needs in China, Yokogawa has added TD-SCDMA terminal testing functions to the VC3300 that support both GSM and TD-SCDMA.

The measurement function for each communication system is provided as a software option.

This means that the function for a new communication standard can be added by simply purchasing additional software, thus eliminating the need for hardware modification.

The test option enables the VC3300 to conduct transmitter and receiver characteristic tests as well as voice loopback tests in a call connected state.

The tuning of chipsets in a Tx/Rx mode noncall state is also supported.

In which the connection of mobile phones to the tester is established using a dedicated testing process, in place of an ordinary connection.

The enhanced VC3300 is aimed at the development, production, quality assurance, and service departments of mobile phone manufacturers The test software option makes the VC3300 ideal for tuning testing and shipment approval testing of call connections, wireless characteristics, voice calls etc for TD-SCDMA mobile phone terminals.
