Vector signal analysis license option for the Rigol RSA800 series spectrum analysers.
The ability to analyse quadrature encoded signals makes it possible to characterise RF modulations, including QAM and QPSK, as well as ASK and FSK signals. You can also validate signals vs preset standards for signals, including GSM, W-CDMA, Bluetooth, 802.11b, Zigbee, and APCO 25.
