Máy Phát Dạng Sóng DDS AT8603B
AT8603B(1Hz~3MHz)
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;
Convenient keyboard operation
Stability and reliability
Technical specification
Frequency
