The AV1695 Microwave Frequency Agile Signal Generator is a professional device produced by Guangzhou Fumin Measurement and Control Technology Co., Ltd. Designed primarily for radar systems, this device can provide dual RF outputs with correlated frequency and phase, and it can modulate the externally input FM signals into pulse form after a required delay. It can be used as a dedicated instrument in the research, production, testing, and maintenance of electronic equipment.

The product features frequency-agile signal output, dual RF outputs with a unified frequency reference, and the ability to modulate input FM signals into pulse form after delay. It has a frequency resolution better than 4Hz, a clear modular circuit design, high reliability, a compact and lightweight design, a high performance-to-price ratio, and a wide power dynamic range. The working frequency ranges from 14.75GHz to 15.25GHz, with a frequency-agile time better than 35us for single RF output and better than 70us for dual RF output (correlated outputs). The stable amplitude power range is from +10dBm to -100dBm, with a power accuracy of ±2dB (+10dBm to -50dBm), and the single-sideband phase noise is less than -80dBc/Hz (at 15GHz frequency point with a frequency offset of 1kHz). Additionally, the device supports programmable internal and external pulse modulation, internal and external triggering, and an FM signal delay range of 100us to 1ms. The input ports include external IF, trigger, and external reference (120MHz), while the output ports feature dual RF outputs, trigger synchronization, and reference.
