2. Connect the provided power cord to the AC power input on the rear panel and plug it into a suitable power outlet.
3. Flip the power master switch on the rear panel to the 'ON' position.
4. Press the power key on the front panel to turn on the device.
5. Connect BNC cables from the CH1 and/or CH2 output terminals to your oscilloscope or other test equipment.
6. For PC control, connect the USB cable from the unit's USB communication interface to your computer.

6. Операција

The FY6900 offers various functions accessible via the front panel controls and menu options.

6.1 Основно генерисање таласних облика

To generate a basic waveform:

1. Press the 'WAVE' function key to select the desired waveform type (e.g., Sine, Square, Triangle).
2. Use the direction keys to navigate to the parameter you wish to adjust (e.g., FREQ, AMPL, OFFSET, DUTY).
3. Turn the knob to change the value of the selected parameter. Press the knob to confirm or switch between coarse/fine adjustment.
4. Ensure the desired output channel (CH1 or CH2) is enabled by pressing its respective 'OK' button.

6.2 Функција Свееп

The sweep function allows the output frequency to vary automatically between a start and stop frequency over a set time. Press the 'SWEEP' function key to access sweep settings. Configure the start frequency, stop frequency, and sweep time using the knob and direction keys. Press 'OK' to start the sweep.

6.3 Frequency Counter

The built-in frequency counter can measure external signals. Connect the external signal to the 'COUNTER' input terminal. Press the 'COUNTER' function key to display the frequency measurement. The video below demonstrates various operational aspects of the FY6900, including waveform generation and interface navigation.
