I. Product Features
The experiment apparatus is tightly close to syllabus of such course as High-frequency Electronic Circuit and the content is full and abundant, which could fully meet the teaching requirement of Communication, Electronics’ major on high-frequency circuit course.
( 1) Adopt the design mode of mainboard with module; there are 14 modules that could be chosen. The coverage range is wider, experiment content is more abundant and the choosing space is bigger, which is convenient for configuration and upgrade.
( 2) The real modularization design: experiment circuit’ s silkscreen is printed on the front side of module while non-regulatory components are welded to the back side, and the plastic transparent cover for protection is installed to the outside, which is not only beautiful, but also convenient for users to observe circuit and components.
( 3) The experiment apparatus integrates DC power supply, cymometer, low-frequency signal source ( with simple sweep frequency source) , high-frequency signal source ( with simple sweep frequency source) and it is an experiment platform with powerful function, which only requires oscilloscope and digital multimeter to complete all experiments.
( 4) High-frequency signal source over 100m, low-frequency signal source over10m, cymometer with 100m and high index are convenient for users to process all kinds of secondary development experiments, innovative experiments, electronic design competition training, course design, graduation design, and etc.
( 5) The experiment content is abundant, and there are altogether 60 experiments, among which, there are 30 basic experiments, 15 system experiments, 10 secondary development experiments and 5 software simulation experiments.
( 6) 5 specialized secondary development modules: synthesis module, bread board module, frequency selective network module, digital modulation demodulation module, video transmission module. Users could process secondary development experiments and innovative experiments on those modules, which could fully exercise their operational ability.
( 7) Adopt professional radio frequency seat and radio frequency connection, and the experiment phenomena are more obvious and performances are more stable.
