Models SG-9500 and SG-9000 are stable high frequency generators capable of AM modulation. They are primarily designed for work on AM and FM radio receivers, but can abe used in any project requiring a modulated RF signal.

Models SG-9200 and SG-9300 are low cost audio generators featuring very low distortion sine wave and a rapid-rise square wave. All models have vernier frequency control for easy tuning and switchable high-low output levels.

Models SG-9300 and SG-9500 have built-in frequency counters which is switchable to measure external frequencies up to 150MHz.
