This signal generator is a device that provides electrical signals at a variety of frequencies, square wave, pulse and output levels. It supports dual mode: PWM mode and PULSE mode. It is used as a signal source or excitation source for testing. Widely used in production practice and technology.Dual mode: PWM mode and PULSE modeLCD high definition displaySupport frequency adjustmentSupport duty cycle adjustmentHigh precision detectionSupport power-down memory function1-Channel signal outputSupport reverse protectionSupport enabled/disabled outputParameter:Model: ZK-PP1KWork voltage: DC 3.3V -30VFrequency range: 1Hz-150KHzFrequency accuracy: 2%Duty cycle range: 0.00%-99%Output Current: less than 30mANumber of pulses: 1-9999 or InfiniteDelay time: 0.000s-9999sPulse width: 0.000s-9999sTime accuracy: 1msOutput amplitude: Same to input voltageWork Temperature: -20 -85¡æWork Humidity: 0% -95%RHSize: 79mm x 43mm x 30mmColour:As ShownMaterial:plasticPackage Contents:1 * Signal GeneratorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
