Product Description

Main Features:

1. The output frequency is a low-jitter square wave with optocoupler isolation output.
2. Frequency range: 0-35kHz adjustable with high accuracy.
3. Communication capability with two selectable modes: TTL or RS232.
4. The duty cycle is non-adjustable.

Usage Instructions:

1. The module is equipped with four buttons and a 12864 LCD display, allowing parameter adjustments via the buttons.
2. The LCD screen displays the current signal frequency, with the displayed value and unit changing accordingly as the frequency changes.
3. The corresponding host computer can be used to input control commands to change the output frequency.
4. The module's frequency control step size is adjustable with step sizes of 1Hz, 1kHz, and 10kHz.
5. The output is controllable; it can be turned on or off.
6. All parameters are retained after power-off.
7. Frequency adjustment supports long press (fast increase or decrease) and short press (min step increase or decrease).
