LCD driver test system doubles throughput
Addressing a surge in demand for liquid crystal displays, the Advantest T6371 offers twice the throughput offered by previous test systems.
Memory test system more than doubles its speed
The Advantest T5375 memory test system is capable of testing up to 128 devices simultaneously at speeds of either 143 or 286MHz DDR.
Due to improved datarates fast enough to handle video streaming and other broadband-dependent Internet applications, wireless LANs are becoming an increasingly popular solution for networking computer equipment without unsightly cables.
Currently, manufacturers are moving forward with the design and production of new high-frequency chips and modules based on the IEEE802.11a high-speed wireless LAN standard.
To ensure that these new wireless networks achieve low bit error rates (BER), manufacturers require improved test instruments that provide highly accurate analysis and evaluation of the chips and modules that make up these networks.
When coupled with Rohde and Schwarz's SMIQ vector signal generator, also available from Advantest, the FSQ is capable of measuring the EVM of RF signals with an impressive average precision of 0.5%.
This makes the FSQ suitable not only for use in improving manufacturing line yields, but also in the precise laboratory analysis of high-frequency signals.
The FSQ family of signal analysers employs a new system architecture that has enhanced its demodulation and analysis bandwidth to 28MHz and provided it with both high sensitivity (55dBm at 2GHz and 1Hz measurement bandwidth) and a wide dynamic range (25dBm TOI at 2GHz.).
This enables the FSQ to capture and analyse signals in accordance with the 802.11a, which uses the widest modulation bandwidth of any current wireless communication standard.
The multifunctional FSQ can also be used for production test of 3G basestation amplifiers.
For example, the FSQ is capable of performing complementary cumulative distribution function measurements of four-carrier 20MHz signals, which allows the user to determine the optimum transmission power for CDMA signals.
Furthermore, the FSQ also comes with an option for IQ input.
Thus, in addition to high-frequency RF signals, when combined with Rohde and Schwarz's AMIQ arbitrary waveform generator, the FSQ can also be used to analyse baseband signals.
