Fy2112s Direct Digital Synthesis (DDS) Signal Generator 5mhz And Frecuency Counter 60mhz With Usb Con

FY2112S series direct digital synthesis signal generator use DDS technology and FPGA
design with the characters of high stability and low distortion ect.,with the function of TTL output
and 60MHz frequency meter.It can output Sine wave, Square wave (Duty cycle adjustable from
1% to 99%) and Triangle wave (include sawtooth wave). Maximum effective output is greater
than 9Vpp with resolution of 0.01Hz (10mHz). Output amplitude and DC offset can be adjusted
continuously. It has two sweep functions, linear sweep and logarithmic sweep. the start and end
frequency and sweep time can be set at will. It’s the ideal equipment of electronic engineer,
laboratory, production lines, the teaching and scientific research.
It has excellent technical indexes and function features:
◆High frequency accuracy: ±5×10－6
◆High resolution: 10 mHz
◆All range continuously adjustable, digital setting.
◆High waveform accuracy: The output waveform synthesis by calculating function.
◆3.3V TTL electric level output.
◆Several different waveforms: Sine wave, Square wave (Duty cycle adjustable) and Triangle
wave (include sawtooth wave).
◆Sweep function: Linear sweep, Logarithmic sweep. Starting and stop points can be set
optionally.
◆Save function: 10 sets of parameters defined by the users can be saved and loaded anytime.
◆Operation mode: Button controlled, LCD display, digital setting, knob adjusted continuously.
◆Output mode：Standard BNC port output.
◆ Highly reliable ： Large scale integrated circuit, Surface mounting technology, reliable and
durable.
◆ Frequency measurement ： Frequency of internal / external signal can be measured through
built-in 60MHz frequency meter.
