The Rohde & Schwarz SMIQ06L is a synthesized signal generator spanning 5 kHz to 6.4 GHz, engineered for research, development, and production testing of communication systems. It delivers high spectral purity and precision modulation across analog, digital, TDMA, CDMA, and W-CDMA standards. The instrument combines a high-grade I/Q modulator with digital signal processor technology to generate complex modulation signals at high bit rates while maintaining minimal error vector magnitude and superior intermodulation suppression.
