The pre-owned Rohde & Schwarz SMIQ04B delivers laboratory-grade vector-signal generation from 300 kHz up to 4.4 GHz with a wide –144 dBm to +13 dBm output span, eliminating external pads for most DUTs. A built-in 30 MHz I/Q path provides ample bandwidth for WLAN, cellular and radar stimuli, while excellent phase-noise performance (≈ –134 dBc/Hz at 1 GHz, 20 kHz offset) preserves tight EVM and ACLR margins. Software-key options unlock standard-compliant GSM/EDGE, WCDMA, CDMA2000 and 802.11b libraries, and the arbitrary baseband generator produces PRBS or complex custom modulation for interference and immunity testing.
Shipped fully tested, freshly calibrated and firmware-current, this SMIQ04B offers immediate deployment and substantial CAPEX savings without compromising Rohde & Schwarz signal purity or SCPI automation.
