Signal Generator Module

Signal Generator Module PWM Pulse Frequency Generator Board Duty Cycle Adjustable Square Rectangular Module XY?LPWM

Pulse Frequency Generator Board

WIDE APPLICATION: The pwm pulse generator is used as square signal generator to generate square for experimental development and use to generate square for controlling motor drivers

SPECIFICATION: XXX (without decimal point): the smallest unit is 1Hz, in the range 1Hz ~ 999Hz, X.XX (one hundred decimal point) is minimum unit 0.01Khz, ranging 1.00Khz ~ 9.99Khz, XX.X (ten in decimal): minimum unit is 0.1kHz; range 10.0KHz ~ 99.9KHz, X.X.X (decimal in ten and one hundred): minimum unit is 1Khz; range 1KHz ~ 150KHz

LCD DISPLAY FUNCTION: The frequency and duty cycle of the LCD display are very clear. This pwm signal generator board can communicate with serial port. All setting parameters are saved after power off

Specification:

Material: Plastic

Frequency range is divided into four, automatic switching:

1.XXX (without decimal point): the smallest unit is 1Hz, in the range 1Hz ~ 999Hz;

2.X.XX (one hundred decimal point) is minimum unit 0.01Khz, ranging 1.00Khz ~ 9.99Khz;

3.XX.X (ten in decimal): minimum unit is 0.1kHz; range 10.0KHz ~ 99.9KHz

4.X.X.X (decimal in ten and one hundred): minimum unit is 1Khz; range 1KHz ~ 150KHz

e.g. frequency display: 100 indicates that the PWM output pulse of 100Hz;

1.01 represents the PWM output pulse 1.01K;

54.1 represents the PWM output pulse 54.1KHz;

1.2.4 indicates that the PWM output pulse of 124KHz;

Duty cycle range: 0 to 100%

All setup parameters, power down save.

I measure PWM frequency and duty cycle with my oscilloscope and was amazed by how accurate things appeared! Both within a few percent at most even for low frequencies! Super impressed with stability and accuracy for the package and price!

This is a really good device. I wish I knew the output current capacity so that I could protect it from shorts.

Did the demo to our VPs without any issues for controlling PWM of FAN, and hence the speed of FAN.

Ordered my second one for a custom build bench test generator, I'm putting this one in a metal cabinet for shielding purposes. They work great. I run them on a 9volt battery. Thanks so much !

Many of the less expensive signal generators/function generators require you to turn off the signal before changing frequencies but this one doesn't. It's easy to increase and decrease the frequency with up and down button presses. It's got a very bright screen and the frequency output is quite accurate. I needed this for a test jig and it's perfect as a reference signal; much easier and less expensive than spending the time to make my own and so much better looking. You will have to solder wires into the input and output but this was perfect for my situation as it made it easy to incorporate.

Does what it is supposed to do well. Very reasonable price, with quick delivery. Also, very good follow-up. Will buy more of these again.
