The pre-owned Rohde & Schwarz SMIQ03B delivers laboratory-grade vector-signal generation from 300 kHz to 3.3 GHz with a wide –144 dBm to +13 dBm level range and fine 0.1 dB resolution, eliminating external pads for most device-under-test scenarios. Its 30 MHz internal I/Q path supports broadband WLAN, cellular and radar stimuli, while excellent phase-noise performance (≈ –134 dBc/Hz at 1 GHz, 20 kHz offset) safeguards stringent EVM and ACLR margins.

Software-key options unlock standards-compliant GSM/EDGE, WCDMA, CDMA2000 and 802.11b waveform libraries, and an arbitrary baseband generator produces custom PRBS or complex modulation for interference and immunity testing. Supplied fully tested, freshly calibrated and firmware-current, this SMIQ03B offers immediate bench deployment and substantial CAPEX savings without compromising Rohde & Schwarz signal purity or remote SCPI automation.
