Product Overview
The 1451 series of shortcut signal generator adopts the design scheme combining direct digital synthesis (DDS) technology and direct analog synthesis (ADS) technology to realize the frequency shortcut covering the whole frequency band from 10MHz to 3/20/40GHz with the shortcut time of less than 150ns, and the dynamic range of the power shortcut is more than 60dB with the shortcut time of less than 200ns, which is equipped with the functions of frequency modulation, phase modulation, amplitude modulation, pulse modulation and vector modulation with the flexible sequence editing interface to realize multi-parameter modulation shortcut. The instrument has high frequency resolution, low phase noise and excellent spectral purity, and also has the functions of FM, PM, AM, pulse modulation and vector modulation. Through the flexible sequence editing interface, multi-parameter modulation shortcut and flexible multi-sequence point shortcut output can be realized. Controlled through the network interface, it can realize external direct frequency control and external sequence control; it provides external IF input interface, which can be used as a shortcut upconverter. The product provides GPIB, LAN, USB, VGA and other standard interfaces, and can be operated by external keyboard and mouse. It adopts 10.1-inch large-screen LCD, which can be operated by multi-window, and the information display is intuitive and rich, and the operation is flexible and convenient. Provide protection for the development, production and maintenance of systems and products in related fields.
