Stability and reliability Convenient keyboard operation

AT8603B(1Hz~3MHz)

Feature

High precise for frequency,high stability.

Purity waveform,small distortion

Non-transition process,fast frequency change-over time

Non-limitation on ranges:Unnecessary to changes ranges,frequency covering factor can be 108

Sweeping characteristics:Many kinds of sweeping modes are selectable and can pause randomly,LED will display the current frequency value;can sweep meticulously on narrow band;can set initial frequency,terminal frequency,sweeping steps and time internal

Modulation characteristic:It has amplitude modulation function,the modulation signal can be generated by either inner signal source or outer input,and the depth is adjusted and will not be affected by carrier wave frequency and out put amplitude;
