STW-GT Series Time and Frequency Generation and Micro-adjustment Products
STW-GT Series Time and Frequency Generation and Micro-adjustment Products
  The STW-GT series of time and Frequency generation and fine-tuning products are used for the generation, display, output fine-tuning, and output signal purification of time and Frequency signals. The products can be equipped with built-in satellite receivers and clock Frequency sources. They can also receive time and Frequency signals from external atomic clock groups or other time and Frequency sources, and perform high-resolution Frequency and phase fine-tuning outputs.
