GSG-120 : Máy phát tín hiệu AM/FM một kênh, 100KHz - 110MHz, thông số cài đặt có thể lưu và sử dụng lại rất dễ dàng
Features:
- Freq Range 100kHz ~ 110MHz
- Output Level -19 ~+99 dBu
- All Operations are Controlled by Microprocessor
- Memory Storage: 10 points in one block (up to 100 continuous points) and 4 output levels
- Memory Data Copy
- Back Space key
- Remote Control
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.
