2 Channel PWM Frequency Duty Cycle Adjustable Wave Rectangle Signal Generator

About this item

• Features: 1. 100percent brand new and high quality. 2. Two independent PWM outputs, which can set the frequency and duty ratio separately. 3. Wide frequency range and high precision. 4. This product can be serial communication. 5. Can be used to generate adjustable pulse for MCU using and control relative circuit. Specification: Condition: 100percent Brand New Operating Voltage: 530V , support micro USB 5.0V power supply Frequency Range: 1Hz150KHz Frequency Precision: 2percent Signal Load Capacity: Output Current is within 830mA Output Range: default 5V Vpp (can be changed by external power) Environment Temperature: 30 ~70 celsius Serial Port Control: Communication Standard:9600 bps Data Bit:8 Stop Bit:1 Verify Bit:none Flow Control:none Weight: Approx. 9g 0.3oz Size: Approx. 41 * 28 * 1.6mm 1.6 * 1.1 * 0.1in Parameter Setting: Module has 3channel key:Set,Up,Down 1. By short press SET key, can shift display 4 parameter values (FR1:PWM1 frequency; dU1:PWM1 duty cycle; FR2:PWM2 frequency; dU2:PWM2 duty cycle); before shifting,there will be corresponding parameter name flashing 2. Directly press UP,DOWN key to modify current parameter value 3. 2chhannel PWM are set 3 kinds frequency value, in frequency display interface,by long press SET to shift, 3 kinds frequency s duty cycle are the same (XXX:1Hz~999Hz; XX.X:0.1Khz~99.9Khz;X.X.X.:1Khz~150Khz) Setting PWM Frequency: 1. S1 FXXXT : set PWM1 frequency as XXX HZ (001~999) 2. S1 FXX.XT : set PWM1 frequency as XX.X KHZ (00.1~99.9) 3. S1 F:X.X.X.T : set PWM1 frequency as XXX KHZ (0.0.1.~1.5.0.) 4. S1 : PWM1 5. S2 : PWM2 6. F : frequency 7. D : duty cycle 8. T : stop sign bit Setting PWM Duty Cycle: 1. S1 DXXXT : set PWM1 duty cycle as XXX(001~100) 2. S2DXXXT : set PWM2 duty cycle as XXX(001~100) Setting successfully back: DOWN Setting unsuccessfully back: FALL Package List: 1 * Wave Rectangle Signal Generator 100percent brand new and high quality. Two independent PWM outputs, which can set the frequency and duty ratio separately. Wide frequency range and high precision. This product can be serial communication.
