• Підключення живлення: Connect the provided power cable to the AC input port on the rear panel of the device. Plug the other end into a standard AC power outlet (AC 85-264V, 47-63Hz).
• Вихід сигналу: Connect your test leads to the CH1 and CH2 output BNC connectors on the front panel.
• USB-підключення (додатково): For PC control and firmware updates, connect the USB data cable from the device's USB port to your computer.
• External Synchronization (Optional): Use the SYNC IN/OUT BNC connectors for external triggering or synchronization with other equipment.

2.3 Початкове ввімкнення

After connecting the power cable, press the power switch on the rear panel to turn on the device. The display will light up, and the system will perform a self-test before entering the main operating interface.

3.1 Панель керування надview

The front panel features a clear LCD display, a numeric keypad, function buttons, and a rotary knob for parameter adjustment. Familiarize yourself with the layout for efficient operation.

3.2 Waveform Generation

The PSG9080 supports various standard and arbitrary waveforms.

• Selecting Waveform Type: Use the 'Wave' button or corresponding menu options to select between Sine, Square, Triangle, Pulse, TTL, or Arbitrary waveforms.
• Коригування частоти: The frequency range for sine waves is 1 nHz-80 MHz. For square waves, it's 1 nHz-30 MHz. Triangle waves range from 1 nHz-50 MHz. Pulse waves and TTL digital waves are 1 nHz-30 MHz and 1 nHz-20 MHz respectively. Arbitrary waves have a range of 1 nHz-50 MHz. Use the numeric keypad and rotary knob to set the desired frequency.
• Amplitude and Offset: Adjust the output signal's amplitude (Vpp) and DC offset using the dedicated controls. The output signal can range from 1 MHz to 25 Vpp.
• Робочий цикл: For square and pulse waves, the duty cycle can be adjusted to modify the waveform's characteristics.

3.3 Dual-Channel Output

The PSG9080 features two independent output channels (CH1 and CH2) with equivalent performance.

• Незалежний контроль: Each channel's parameters (waveform type, frequency, amplitude, offset, duty cycle) can be set independently.
• Регулювання фази: The phase difference between CH1 and CH2 is continuously adjustable from 0 to 359.9 degrees, allowing for precise phase-related testing.

3.4 Розширені функції

• Програмований вихід: The device allows you to formulate the waveform output type, output time, and output sequence freely to achieve automated testing and complex signal generation.
• Modulation Function: Modulated waveforms can be output on single or dual channels. This function allows for adding information from a signal source to a carrier wave, making it suitable for channel transmission and various communication tests.
• томtage-Controlled Adjustment (VCA): Частота, ampОсвітлення та робочий цикл виходу можуть контролюватися зовнішнім аналоговим регулятором об'єму.tage signal. This feature is widely used in industrial debugging for voltage-controlled sweep frequency, sweep amplitude, and sweep duty cycle applications.
• Режим вимірювання: The device can also function in measurement mode to display frequency, positive/negative pulse width, period, and duty cycle.
