_x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ The signal generator is a device that provides electrical signals at a variety offrequencies, square wave, and output levels. It is used as a signal source or excitation source for testing. There are 2 modes supported. Normal Mode: Frequency range 1Hz~150KHz, duty cycle range 0.00%-100%. duty cycle accuracy 1%. Exact Mode: Frequency range 1Hz~15KHz, duty cycle range 0.00%-100%, duty cycle accuracy 0.1%. Work Voltage: DC 3.3V-30V Frequency Accuracy: 2% Duty Cycle Range: 0. 00%-100% Output Current: About 5-30mA Output Amplitude: Same to input voltage Work Temperature: -104~185(-40~85) Work Humidity: 0%~95%RH Parameter Setting: This product adjusts the frequency and duty cycle by rotating the potentiometer. It can realize rapid adjustment according to the rotation speed. By default, adjust the duty cycle. Short press the adjustment frequency, long press for 2 seconds to lock, and long press for 5 seconds to switch the mode (normal mode/exact mode). The operation is simple. After setting, the parameters are automatically saved and will not be lost in power failure. The frequency is divided into 4 ranges and switched automatically. 1. XXX: minimum unit 1Hz, value range 1Hz~999Hz. 2. X.XX: minimum unit 0.01kHz, value range 1.00kHz~9.99kHz. 3. XX.X: minimum unit 0.1kHz; value range 10.0kHz~99.9kHz. 4. X.X.X: minimum unit 1kHz; value range 1kHz~150kHz. color:Black Material:ABS size:71 x 39mm Package Contents: 2 x Signal Generator Only the above package content, other products are not included.
