AT2818 adopts true-color TFT-LCD and English operation interface (Chinese also available). AT2818 (Rev B2.0) has been upgraded into continuous frequency with the resolution of 0.001Hz.

Four parameters can be measured simultaneously by AT2818, Any parameters can be set arbitrarily. Both main & sub parameters can be displayed in 6 dgt after the improvement. AT2818 can not only scan 10 kinds of frequency or voltage level list, but also correct three groups of user frequency so as to improve the accuracy.
