The new Model 2345 from Yokogawa is a portable digital clamp-on tester designed for measurement applications involving high-frequency components.
It has a demodulation frequency bandwidth (-3 dB) of 120 MHz, and input frequency ranges of 220 MHz to 3.2 GHz, and 4.96 GHz to 6.2 GHz, with 0.1 Hz 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 RS-232 and GPIB interfaces, and a sampling clock generation function is available as an option.
