2. Setup

2.1 Unpacking and Inspection

Carefully remove the spectrum analyzer from its packaging. Inspect the device for any signs of physical damage that may have occurred during transit. Retain the packaging materials for future transportation or storage.

2.2 Power Connection

Connect the provided power cord to the AC input on the rear panel of the device. Ensure the power source meets the specified requirements: 100V - 240V AC, 50/60Hz. The power input is located on the rear of the unit, typically near the fuse holder.

2.3 Connecting RF Input and Tracking Generator Output

The front panel features the RF Input and Tracking Generator Output connectors. Both are N-type female connectors with a 50 Ω impedance.

• RF Input: Connect the signal to be analyzed to the RF Input connector. Observe the maximum safe reverse level of +30 dBm / 50 VDC.
• Tracking Generator Output: Use this connector to output a tracking signal for characterization of devices under test. The maximum safe reverse level is +20 dBm / 50 VDC.

2.4 Communication Ports

The rear panel provides various communication ports for external connectivity:

• USB HOST: For connecting USB storage devices to save data.
• USB DEVICE: For connecting the analyzer to a computer.
• LAN: For network connectivity and remote control.
• VGA: For connecting an external display.
• Earphone Port: For audio output.
• 10 M Reference Input: 50 Ω, N-type female connector for an external 10 MHz reference clock.

3. Operating Instructions

3.1 Powering On and Basic Interface

Press the 'On/Off' button on the front panel to power on the device. The 10.4-inch TFT LCD will display the main measurement interface. The interface is designed with clear color, size, and shape distinctions for buttons and function areas, facilitating quick adjustments.

3.2 Setting Frequency Parameters

To set the frequency range for your measurement:

1. Press the FREQ button on the control panel.
2. Use the soft keys on the display or the numeric keypad to enter values for:
• Center Freq: Sets the center frequency of the displayed span.
• Start Freq: Sets the lowest frequency of the displayed span.
• Stop Freq: Sets the highest frequency of the displayed span.
• Span: Sets the frequency range displayed on the screen.
3. Adjust the Resolution Bandwidth (RBW) by pressing the BW button and selecting the desired value. The minimum RBW is 10 Hz.

3.3 Setting Amplitude Parameters

To control the vertical scale of the display:

1. Press the AMPTD button.
2. Adjust the Reference Level to set the top line of the display in dBm.
3. Adjust the Attenuation to prevent input overload and optimize the signal-to-noise ratio.

3.4 Using the Tracking Generator

The integrated tracking generator can be used to characterize the frequency response of filters, amplifiers, and other RF components.

1. Connect the Tracking Generator Output to the input of the device under test (DUT).
2. Connect the output of the DUT to the RF Input of the spectrum analyzer.
3. Enable the tracking generator function through the menu.
4. Set the desired output power level (range: -30 dBm to 0 dBm).
5. The spectrum analyzer will sweep synchronously with the tracking generator, displaying the DUT's frequency response.

3.5 Saving and Recalling Data

To save measurement data or instrument settings:

1. Insert a USB storage device into the USB HOST port on the front panel.
2. Press the Save button on the control panel.
3. Follow the on-screen prompts to save the current trace, screenshot, or instrument settings to the USB device.
4. To recall saved data, press the Recall button and select the desired file from the USB device.

4. Maintenance

4.1 Cleaning

To clean the instrument, use a soft, damp cloth. Do not use abrasive cleaners or solvents that could damage the display or casing. Ensure the device is powered off and disconnected from the power source before cleaning.
