0.01Hz-8MHz Direct Digital Frequency Synthesizers Triangle/Square/Sine Wave Pulse Function Signal Generator #090957 Product Description Instrument introduction: This signal generators based on direct digital synthesis(DDS) technology, are deigned by adopting FPGA,it has the character sof high stability and low distortion ect,one channel output,one channel TTL output, external frequency measurement,counter,etc.,and output signals are capable of regulating amplitude and DC bias. UDB100xS series have a sweep function and can freely set sweep range and scanning time. UDB100xS series are applicable to laboratories and are used by engineering technicians and enthusiasts. Basic technology data: Signal output function: Output wave forms:Sine wave,Square wave,Triangle wave Output amplitude: ≥9Vp-p (signal output,noload) Output impedance: 50Ω±10% DC offset: ±2.5V(noload) Display: LCD1602 With communication function, can connect the PC to control Frequency range: 0.01Hz~8MHz Frequency resolution: 0.01Hz(10mHz) Frequency Stability: ±1×10-6 Frequency accuracy: ±5×10 -6 Sine wave distortion: ≤0.8%(reference frequency is 1kHz) Trinagle wave linearity: ≥98% (0.01Hz~10kHz) Rise and fall time of square wave: ≤100ns Square wave duty range: 1%~99% TTL output function: Frequency range: 0.01Hz~8MHz Amplitude:>3Vp-p Fan out coefficient >20 TTL Load COUNTER function: Counter range: 0~4294967295 Frequency measurement range: 1Hz~60MHz Input voltage range: 0.5Vp-p~20Vp-p SWEEP function: Frequency range: fM1~fM2(frequency can be freely set) Input voltage range: 0.5Vp-p~20Vp-p Other functions: Save and load parameter: M0~M9(M0:default load) Function description: 1. Power switch 2. Offset regulation 3. Amplitude regulation 4.Signal output terminal 5. Encoder adjusting 6. User key 7. Communication interface 8. LCD display 9. DC5V Power input Operating instructions: 1.Select key can select between regulating frequency and regulating function, " * "on the left of screen can indicate whether in regulating frequency or regulating functionin current. 2.During regulating frequency, press the and key can move regulation positions leftwards and rightwards, and press the "OK" key can switch the frequency units(HzkHz and MHz).At the moment,rotary coding switch can regulating frequency. 3.During regulating function,press the and key can select projects needing being regulated, mainly including "WAVE", "DUTY","COUNTER","EXT.FREQ","SAVE","LOAD","SWEEP". 4.WAVE represents waveform regulation, press OK key can change the current waveform, SIN represents sine wave,TRI represents triangular wave,and SQR represents square wave. 5.DUTY represents duty ratio regulation,now regulate the encoder can regulate duty ratio, SQR can be regulated between 0.1% and 99.9%;TRI have three situations,namely,standard triangular wave in 50.0%,rise sawtooth wave in above 50.0%,and fall sawtooth wave in below 50.0%;and SIN is invalid. 6. COUNTER represents counter function, which starts to count after ExtInput input pulse,the screen displays count value,press the OK key to clear 0 and re-count. 7.EXT.FREQ represents external frequency measurement function, which can measure frequency of the ExtInput input signal. 8.SAVE represents storage function, which can store current frequency value,current waveform and duty ratio data in internal memory so as to be called out in next time, there is 10 storage positions o f0-9,which can be regulated through encoder, press the OK to save after selecting the storage position, now OK appearing in the lower-right corner of the screen in dicate successful storage, if you save current data in the position 0,the value is called in in default when next-time startup. M1 and M2 have special meanings, M1 is start frequency, M2 is stop frequency, and if sweep function is needed to be used,values of M1 and M2 are needed to be set,and fM2>fM1 is ensured. 9.LOAD represents parameters called in storage,specific operations are similar to SAVE,so the same will not be repeated here. 10.TIME is the function of set sweep time,with set range of 1s~99s. 11.SWEEP represents sweep function,default setting is STOP,press the OK key to -6- start to scan,and at this moment output signal frequency continuously changes from fM1 to fM2, where in frequencies of M1 and M2 need to be set by using SAVE function,and scanning time needs to be setby using TIME function. 12.TTL output the synchronized TTL wave of the same frequency. 13.OFFSET on the right is DC bias regulating knob, and AMPLITUDE is amplitude regulating knob.
