    Product Description

    The GSG-Series are FM/AM standard signal generators providing CW, AM, and FM signals from 100kHz to 110MHz with the calibrated output levels from -19dB to 99dB in 1dB step. The intuitive user interface of the GSG-Series enables free combinations of frequency, output level, and modulation. Output settings can be stored and recalled easily; 10 points in one block up to 100 continuous points, with 4 independent output levels. Remote controlling is available with the optional GRC-1201 unit which enhances the memory recall function from a distance. All these superior features of GSG-Series cover most of the applications in receiver manufacturing and maintenance industries.

    * Now GSG-122 is discoutinued.
