5. Arahan Operasi
The FY6900 offers a wide range of functions for signal generation. This section outlines basic operation.
5.1 Penjanaan Bentuk Gelombang Asas
To generate a basic waveform:
- Pilih Saluran: Use the CH1 or CH2 buttons to select the desired output channel.
- Pilih Jenis Bentuk Gelombang: Tekan ke GELOMBANG function shortcut key. Use the direction keys or knob to navigate through waveform types (Sine, Square, Triangle, etc.) and press OK untuk mengesahkan.
- Laraskan Parameter: Use the direction keys to highlight parameters such as Frequency, Amplitude, Offset, and Duty Cycle. Rotate the knob button to adjust the value. Press OK untuk mengesahkan nilai.
- Dayakan Output: Ensure the selected channel's output is enabled (usually indicated on the display).
5.2 Operasi Dwi-Saluran
The FY6900 features fully independent dual-channel output, allowing for synchronous operation with precisely adjustable phase differences.
- Kawalan Bebas: Each channel (CH1 and CH2) can be configured with different waveform types, frequencies, amplitudes, and offsets.
- Penjejakan Saluran: Activate the channel tracking function to synchronize parameters between both channels. When tracking is enabled, changes to one channel's parameters can be applied to the other based on user configuration.
- Pelarasan Fasa: In synchronous mode, the phase difference between CH1 and CH2 can be precisely adjusted.
5.3 Penjanaan Bentuk Gelombang Sewenang-wenangnya
The device supports up to 98 sets of functions/arbitrary waveforms, including 34 preset waveforms and 64 user-defined waveforms. It has 64 sets of arbitrary wave storage bits, each with a storage depth of 8192*14bits.
