High bandwith and resolution from I/Q demodulator

Yokogawa has introduced a wideband I/Q demodulator which provides novel high-bandwidth high-resolution capabilities.

Yokogawa has introduced a wideband I/Q (in-phase/quadrature) demodulator which provides unique high-bandwidth/high-resolution capabilities as a key element in test systems for wireless LANs, digital broadcasting and advanced mobile communications networks.

The new VN6000 provides down-conversion from RF to baseband frequencies as well as demodulation.

It has a demodulation frequency bandwidth (-3dB) of 120MHz, and input frequency ranges of 220MHz to 3.2GHz, and 4.96 to 6.2GHz, with 0.1Hz resolution.

Optional high-speed digitisers are available together with generation and analysis software for EVM (error vector magnitude) and BER (bit error rate) measurements.

Transmitter and receiver testing can be carried out for the IEEE802.11a, Hiperlan/2 (OFDM) and IEEE802.11b (CCK) standards.

The instrument features RS232 and GPIB interfaces, and a sampling clock generation function is available as an option.
