The Rohde & Schwarz SMT02 is a benchtop signal generator covering 5 kHz to 1.5 GHz with output power from −144 dBm to +16 dBm (±1 dB accuracy). It delivers high signal purity, programmable sweep functions, and multiple modulation modes—AM, FM, phase, and pulse—making it ideal for RF component development, receiver measurements, and EMC testing. The instrument features 0.1 Hz frequency resolution, 25 ms switching time, and optional OCXO time base stability below 1 × 10⁻⁹/day. A large backlit LCD display and IEEE 488 SCPI interface enable straightforward benchtop operation and automated test sequences.
