5. Інструкцыя па эксплуатацыі

The ICL8038 module allows for adjustment of frequency, waveform type, duty cycle, and output amplitude. Use the onboard potentiometers and frequency selection points as described below.

5.1 Рэгуляванне частаты

• Frequency Potentiometer: Adjust the potentiometer labeled "Frequency adjustment" (RP2 in Figure 4.1) to fine-tune the output frequency within the selected range.
• Frequency Range Selection: The module supports multiple frequency ranges. These are typically selected by connecting specific capacitor points (C3-C7 in Figure 4.1). The ranges are:
  • 10 Гц-450 Гц
  • 90 Гц-1.5 кГц
  • 940 Гц-15 кГц
  • 6 кГц-120 кГц
  • 20 кГц-450 кГц
  Note: The exact method for selecting these ranges (e.g., jumpers, switches) may vary. Refer to the module's silkscreen for specific instructions if not immediately apparent.

5.2 Выбар сігналу

The module can generate sine, triangular, and square waveforms. The selection points for these waveforms are indicated on the module (see Figure 4.1). Typically, these are jumper pins where you can select the desired waveform output.

• Square Wave: Select the square wave output.
• Triangle Wave: Select the triangle wave output.
• Сінусоіда: Select the sine wave output.

5.3 Duty Cycle Adjustment (Square Wave)

For square wave output, the duty cycle can be adjusted from 2% to 98% using the potentiometer labeled "Square wave duty cycle adjustment" (RP1 in Figure 4.1).

5.4 Выхад Amplitude Adjustment

The amplitude of the output signal can be adjusted using the potentiometer labeled "Output amplitude adjustment" (RP3 in Figure 4.1).

5.5 Waveform Linearity Adjustments

• Square Wave Linear Adjustment: Use the potentiometer labeled "Square wave linear adjustment" (RP5 in Figure 4.1) to optimize the linearity of the square wave.
• Positive Twisted Wave Linear Adjustment: Use the potentiometer labeled "Positive twisted wave linear adjustment" (RP4 in Figure 4.1) for fine-tuning the linearity of the positive portion of the waveform, particularly for sine and triangle waves.
