Signal generators of the R&S SMY family from Rohde & Schwarz are cost-effective instruments for testing AM, FM and jM receivers as well as for component measurements. 

Designed exclusively for the main applications of signal generators by cutting out the unnecessaries, R&S SMY features an outstanding price/performance ratio. Thanks to its comprehensive basic features and excellent signal characteristics, it is an economical solution for universal use in lab, production and servicing environments.

• Level range -140 dBm to +13 dBm 19 dBm overrange, sufficient even for receivers of highest sensitivity
• High level accuracy and low RF leakage allowing accurate and undegraded sensitivity measurements
• FM-DC with high accuracy of carrier frequency for testing pagers and receivers fitted with digital squelches
• Low SSB phase noise and high spurious rejection for all in-channel and blocking measurements
• Low residual FM affording ample of margin for S/N measurements
• Modulation generator 1 Hz to 500 kHz for modulation frequency response measurements
• Stereo channel separation of 50 dB and low harmonic distortion for testing FM stereo receivers
• Non-interrupting level setting over a range of 20 dB for reproducible measurement of squelch hysteresis
• Frequency resolution 1 Hz, suitable also for narrowband test items
• FM-DC, deviation up to 20 MHz for VCO simulation
• FM bandwidth 2 MHz for fast FSK and telemetry applications
• High output level up to 19 dBm (25 dBm with option R&S SMY-B40) for component and overdrive testing
• AF synthesizer 1 Hz to 500 kHz, separate use as AF signal source for external applications possible, eg recording of AF frequency response
• Remote-control interface IEC625/IEEE488 for use in automatic test systems
• RF sweep
• Sequence function and SEQ input for semi-automatic use
