Rohde and Schwarz SMIQ06ATE Vector Signal Generator, 300 kHz to 6.4 GHz

The Rohde & Schwarz SMIQ06ATE is a vector signal generator purpose-built for automated test equipment (ATE) environments, delivering high-accuracy modulation signals across 300 kHz to 6.4 GHz. It employs DSP technology and a broadband I/Q modulator to generate digital modulation signals with excellent vector accuracy, alongside analog modulation capability. The instrument supports multiple digital radio protocols including IS-95 CDMA, W-CDMA, and 3GPP W-CDMA via optional modules.

Full programmability via IEEE 488 remote control eliminates the need for manual front-panel operation, making it ideal for integrated ATE systems where rear-panel RF and LF connections streamline signal routing and test automation.
