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.

Industry Background & Resource Sourcing

Over the past two decades, rapid advances in China’s radio-frequency sector have shortened production-line refresh cycles to roughly 3–5 years. Leveraging long-term partnerships with equipment OEMs, research institutes, and calibration labs, TESTRO acquires traceable, well-maintained decommissioned or replacement units. Every instrument undergoes a five-step technical check and third-party calibration before entering stock, ensuring reliable performance data.
