5. Operating Instructions
The FY8300S-20M offers a user-friendly interface for generating various waveforms. The main controls include function buttons, a rotary encoder for value adjustment, and channel-specific output controls.
5.1 Basic Waveform Generation
- Select Channel: Press the CH1, CH2, or CH3 button to select the desired output channel.
- Select Waveform: Press the WAVE button to cycle through available waveforms (Sine, Square, Triangle, Pulse, Arbitrary, etc.).
- Adjust Frequency: Use the rotary encoder to adjust the frequency. Press the encoder to switch between coarse and fine adjustment.
- Adjust Amplitude: Press the AMPL button and use the rotary encoder to set the desired peak-to-peak amplitude.
- Adjust Offset: Press the OFFS button and use the rotary encoder to set the DC offset.
- Enable Output: Ensure the selected channel's output is enabled (usually indicated by an LED or on-screen icon).
5.2 Advanced Functions
- Arbitrary Waveform: The device supports up to 98 arbitrary waveforms. Refer to the detailed software manual for creating and loading custom waveforms.
- Pulse Generation: For pulse waveforms, adjust pulse width and pulse frequency independently. The pulse amplitude can also be set.
- Phase Adjustment: For multi-channel synchronous operation, adjust the phase difference between channels (0 to 359.99°).
- Frequency Counter: Use the COUNTER function to measure external frequencies.
- Saving Settings: Press and hold the OK key to save the current instrument parameters. These settings will be automatically loaded upon the next startup.
