RF & Audio Generators
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.
Features SG-9000/SG-9500:
RF frequencies continuously variable 100kHz to 450MHz in six ranges
Output RF voltage variable and has 20dB attenuator switch
Internal AM modulation of 1kHz
Audio 1kHz signal available at output
External crystal locks oscillator to your frequency between 1-15MHz
455kHz, 4.5MHz and 10.7MHz specially noted for easy setting
