4.2 Power Connection
- Ensure the power switch is in the OFF position.
- Connect the supplied AC power cord to the AC Power Connector on the rear panel of the instrument.
- Plug the other end of the power cord into a grounded AC power outlet.
4.3 Initial Power On
Press the Power Key on the front panel to turn on the instrument. The system will perform a self-test and then display the main measurement interface.
5. Operating Instructions
5.1 Basic Measurement Setup
To perform a basic spectrum measurement:
- Connect the signal source to the RF Input Connector.
- Press the FREQ key to set the Center Frequency and Span. Use the numeric keypad or the knob for adjustment.
- Press the BW key to adjust the Resolution Bandwidth (RBW) and Video Bandwidth (VBW). A 1Hz minimum RBW allows for effective distinction of nearby signals.
- Press the AMPTD key to set the Reference Level and Attenuation.
- Observe the spectrum display on the 9-inch high-resolution LCD.

5.2 Quick Detection Function
The XSA815TG features a quick detection function for ASK/FSK modulated signals, commonly found in automotive remote controls and small radio modules. This function allows for direct retrieval of average frequency, power, and offset parameters.
- Navigate to the Quick Detection menu (refer to the on-screen menu for exact path).
- Apply the ASK/FSK signal to the RF Input.
- The analyzer will automatically capture and display the relevant parameters.
Figure 6: Quick Capture Function displaying an ASK/FSK signal.
5.3 EMC Test Function (Optional)
With optional software, the XSA815 can perform EMC pre-compliance tests. It integrates over 200 common EMC test standards.
- Ensure the optional EMC test software is installed and activated.
- Select the desired EMC test standard from the menu.
- The software will automatically configure the spectrum analyzer for the test.
- Perform the test, and the data will be recorded and compared against the selected standard.
5.4 Waterfall Chart Analysis
The Waterfall Chart feature allows you to visualize the behavior of signal parameters over time, which is particularly useful for analyzing intermittent signals or signal stability.
- Access the Waterfall Chart function from the display menu.
- The display will show a 3D representation of frequency, amplitude, and time.
- Analyze the chart to identify changes in signal characteristics or intermittent interference.
6. Maintenance
6.1 Cleaning
To maintain the performance and appearance of your XSA815:
- Always disconnect the power cord before cleaning.
- Use a soft, lint-free cloth dampened with a mild, non-abrasive cleaner to wipe the exterior surfaces.
- Do not use harsh chemicals, solvents, or abrasive materials, as these can damage the casing or display.
- Ensure no liquid enters the instrument through ventilation openings or connectors.
6.2 Storage
When not in use for extended periods, store the instrument in a cool, dry place, away from direct sunlight and extreme temperatures. Use the original packaging or a suitable protective case to prevent dust accumulation and physical damage.
7. Troubleshooting
This section provides solutions to common issues you might encounter. If the problem persists, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Instrument does not power on. | Power cord not connected; Power outlet faulty; Internal fuse blown. | Check power cord connection; Test power outlet; Contact service for fuse replacement. |
