5. Setup

Unpacking: Carefully remove the signal generator and its accessories from the packaging. Verify that all components listed in the package list are present: 1x Signal Generator, 1x Power Cord.
Power Connection: Connect the provided 12VDC power cord to the DC input port on the signal generator. Plug the other end of the power cord into a suitable 12VDC power outlet.
RF Output Connection: Connect your test equipment (e.g., spectrum analyzer, oscilloscope, antenna) to the RFOUT BNC connector on the front panel using an appropriate coaxial cable.
Positioning: Place the signal generator on a stable, flat surface. The integrated stand can be used to angle the device for better visibility.

6. Operating Instructions

The signal generator is controlled via its front panel display and keypad.

6.1 Power On/Off

To power on, ensure the 12VDC power supply is connected. The device should automatically power on and display the default frequency.
To power off, disconnect the 12VDC power supply.

6.2 Setting Frequency

Use the numerical keypad (0-9) to enter the desired frequency.
The decimal point button can be used for precise frequency entry.
The device supports 7-digit frequency input. For example, to set 439.0125 MHz, you would enter '4390125' (representing 439012.5 KHz). The display will show the entered value.
Press an appropriate function key (e.g., F1, F2, F3, F4) or an 'Enter' equivalent (if available, not explicitly detailed in provided data) to confirm the frequency.

6.3 Adjusting Signal Power

The signal power can be adjusted within the range of -70 dBm to 132 dBm. Specific controls for power adjustment are typically accessed via function keys or dedicated buttons. Refer to the on-screen menu or specific button labels for power level control.

6.4 Selecting Modulation Type

The device supports AM, FM, PM, and Pulse modulation. Use the function keys (F1-F4) or menu options to cycle through or select the desired modulation type. The 800 Hz tone modulation is built-in and can be activated as needed.

7. Maintenance

Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use liquid cleaners or solvents.
Storage: When not in use, store the signal generator in a cool, dry place, away from direct sunlight and extreme temperatures.
Inspection: Periodically inspect the power cord and connectors for any signs of damage.

8. Troubleshooting

Problem	Possible Cause	Solution
Device does not power on	No power supply, incorrect power supply, faulty power cord	Ensure 12VDC power supply is correctly connected and functional. Check power cord for damage.
No RF output signal	Incorrect frequency/power settings, faulty output cable, device malfunction	Verify frequency and power settings. Check the coaxial cable connection. If problem persists, contact support.
Display is blank or unreadable	Power issue, display malfunction	Check power connection. If power is present and display remains blank, contact support.

9. Warranty and Support

For warranty information or technical support, please refer to the documentation provided at the time of purchase or contact your retailer. Keep your purchase receipt as proof of purchase.
