6. Bedryfsinstruksies
6.1 Basiese werking
- Kies kanaal: Druk die CH1/2 button to select either Channel 1 or Channel 2 for adjustment. The active channel will be indicated on the display.
- Kies golfvorm: Druk die GOLF knoppie. Gebruik die AANPAS knob to scroll through available waveform types (Sine, Square, Pulse, etc.). Press OK om jou keuse te bevestig.
- Pas frekwensie aan: With a waveform selected, the frequency parameter will typically be highlighted. Use the AANPAS knob to change the frequency. Press STEL to change the digit being adjusted for finer control.
- Pas aan Amplitude: Druk die AMPL knoppie. Gebruik die AANPAS knob to set the desired output amplitude. Press OK te bevestig.
- Adjust Offset (Bias): Depending on the waveform, you may be able to adjust the DC offset. This is typically accessed via the AMPL button or a combination with SKUIF. Gebruik die AANPAS knob to set the offset.
6.2 Advanced Waveform Settings
