Instek RF Training kit set, designed for wireless frequency range applications. Includes a 880 MHz digital PLL and 2.4GHz microstrip line filter circuits. Include these applications of RF Transmitter and Receiver both. Training for the Voice Communication System. Demonstrates the applications and measurements for using spectrum analyzers in communication instruments. Specific RF circuit characteristics and PCB Layout on each module. Training system covering 22 modules, and over 50 experiments. The GRF-3300 Series training system is designed for a high frequency range of wireless applications. This superior system is equipped with digital phase-locked loop (PLL) and a microstrip line filter (MLF) with a design range from 730 MHz up to 960 MHz / 2.4 GHz which is increasingly important in the education field. By using the Wireless Voice Communication system, students can practically complement their learning. The GRF-3300 with the combination of a training syllabus, basic theory, systematic demonstrations, and hands-on experiments make it the perfect match for modern RF communication education. The spectrum analyzer used in the training system is not only capable of experimenting with measurement testing, but is also a standard industrial instrument itself, making it practical for students to adapt in the occupational field. AC 110V or 220V, 50/60Hz power Source, 100 MHz Bandwidth. Measures 560mm width by 170mm height by 530mm depth.
