This is a microcontroller based equipment with lcd. The analog metres have multiple scales which makes the instrument very complicated for the students. The digital display of swr & db solves the problem. Since the equipment have microcontroller based digital display so there is no need of expanded scales, as it was in conventional instruments.

Ltekonline are the manufacturers of VSWR Meter used to demonstrate engineering principles in Engineering Colleges, Engineering Schools and Microwave Engineering Lab Equipments for Engineering Teaching Lab in Universities
