Signal generator
1. This sensor can output sine wave, square wave, triangle wave, sawtooth wave, DC voltage; voltage sensor can be used to measure the output waveform;
2. How to choose which waveform to output on the sensor with screen, and how to adjust the frequency, amplitude, and duty cycle of the output waveform, the specific steps are as follows:
(1) Turn on the sensor, and the data displayed on the main interface is "0", which means that the waveform is not output; remember that the following operations such as selecting the waveform can be performed in this state;
(2) Tap the "Power On Key" to enter the waveform selection and waveform adjustment interface; at this time, the interface displays 5-digit data, ID+number;
(3) Select the waveform that needs to be output: short press the "Bluetooth function switch key", the number after the ID will change, and different number numbers represent different waveforms; (1 sine wave, 2 square wave, 3 triangle wave, 4 Sawtooth wave, 5 DC voltage); select a good waveform, for example, now select "2", that is, select the square wave to be output;
(4) Select the output frequency of the waveform. The 5-digit data displayed on the interface is the output frequency of the waveform. For example, if the frequency is adjusted to 10Hz, the method is as follows: short press the "Save data key" to move the cursor of the adjustment data Position, adjust the cursor to the tens position, and then short press the "Shift function key", you can adjust the size of each digit, adjust the tens position to 1, and adjust the speed to 0 at other positions, so you can select The output frequency of the waveform is 10Hz;
(5) Select the maximum value of the waveform; short press the "backlight switch key", the S6 position on the left side of the screen is on, and the maximum value of the waveform output can be adjusted at this time. Use the "Shift" and "Save" buttons to adjust the size , For example, the maximum value is now 6;
(6) Select the minimum value of the waveform; short press the "backlight switch key", the S9 position on the left side of the screen is on, and the minimum value of the waveform output can be adjusted at this time. Use the "Shift" and "Save" buttons to adjust the size , For example, the minimum value is now 0;
Note: The amplitude range of the waveform is: 0-12
(7) Select the duty cycle of the waveform (only the square wave needs to select the duty cycle); short press the "backlight switch key", the S10 position on the left side of the screen will be on, and the duty cycle of the waveform can be adjusted at this time, use "Shift "" and "Save" two buttons to adjust the size, for example, now select the duty cycle as 20;
(8) After completing steps 2-7, tap the "Power On Key" to return to the initial main interface (the interface where the displayed data is "0");
(9) Output waveform: lightly press the "Shift function key", the data displayed on the main interface becomes "1", which means that the waveform frequency is 10Hz, the maximum value of the waveform is 6, the minimum value is 0, and the duty cycle It is a square wave waveform of 20; the next time it is turned on, the default is the selected waveform and its parameters;
