| Abstract: | DDS is a new technique in the field of frequency synthesis. It owns the merits of shorter response time, high accuracy, and so on. Though the converting speed of PLL is low, it works very stable. VXI bus owns the merits of smaller dimension, better transplanting ability, and so on. It is excellent instrument platform in 21st century, it has shown huge power of market competition with the merits of lower consumption, very good instinct of movable and its price compared with traditional instruments. |
