2. Sikkerhedsoplysninger
Please read all safety information carefully before operating the device to ensure safe and proper use.
- Strømforsyning: Use only the power adapter supplied with the instrument. Ensure the power source matches the voltagde krav, der er specificeret på enheden.
- Miljø: Operate the analyzer in a dry, well-ventilated area. Avoid exposure to extreme temperatures, humidity, dust, or corrosive gases.
- Ventilation: Bloker ikke ventilationsåbningerne på instrumentet. Tilstrækkelig luftgennemstrømning er afgørende for at forhindre overophedning.
- Rensning: Afbryd strømmen før rengøring. Brug en blød, tør klud. Brug ikke flydende rengøringsmidler eller aerosolrengøringsmidler.
- Service: Forsøg ikke selv at servicere instrumentet. Overlad al service til kvalificeret servicepersonale.
- Input Limits: Overhold den maksimale indgangsvolumentage and power limits specified for the RF input connector to prevent damage to the device.

4. Opsætning
4.1 Udpakning og inspektion
Upon receiving your OWON XSA815, carefully inspect the packaging for any signs of damage. Unpack the instrument and all accessories. Verify that all items listed in the packing list are present and undamaged. If any items are missing or damaged, contact your supplier immediately.
Figure 4: OWON XSA815 Spectrum Analyzer and included accessories.
4.2 Strømtilslutning
- Sørg for, at afbryderen er i OFF-positionen.
- Connect the supplied AC power cord to the AC Power Connector on the rear panel of the instrument.
- Sæt den anden ende af netledningen i en jordet stikkontakt.
4.3 Indledende tænding
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. Betjeningsvejledning
5.1 Basic Measurement Setup
To perform a basic spectrum measurement:
- Connect the signal source to the RF Input Connector.
- Tryk på FREKV key to set the Center Frequency and Span. Use the numeric keypad or the knob for adjustment.
- Tryk på BW key to adjust the Resolution Bandwidth (RBW) and Video Bandwidth (VBW). A 1Hz minimum RBW allows for effective distinction of nearby signals.
- Tryk på 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. Vedligeholdelse
6.1 Rengøring
To maintain the performance and appearance of your XSA815:
- Tag altid netledningen ud før rengøring.
- Brug en blød, fnugfri klud 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 eller display.
- Ensure no liquid enters the instrument through ventilation openings or connectors.
6.2 Opbevaring
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.
