Spectrum analyzer OWON XSA1032

Order the OWON XSA1032 Spectrum Analyzer for accurate RF analysis and tuning of your drone's FPV systems

The OWON XSA1032 Spectrum Analyzer is a professional benchtop instrument designed for detailed analysis of RF signals in the range from 9 kHz to 3.2 GHz. The device is ideal for setting up antenna-feeder paths, diagnosing interference, testing video transmitters and receivers of FPV systems.

With high 1Hz resolution and low noise, this analyzer allows you to see the finest signal details, which is critical for ensuring stable and clear video broadcasts over long distances.

• Wide frequency range from 9 kHz to 3.2 GHz for comprehensive RF analysis.
• 1 Hz frequency resolution for detecting the smallest signals.
• Low self-noise down to -160 dBm for working with weak signals.
• Built-in tracking generator (model XSA1032-TG) for measuring filter and antenna characteristics.
• Large 10.4-inch TFT display and USB, LAN, VGA interfaces for convenient operation.

How does the OWON XSA1032 spectrum analyzer work?

The device receives the signal under study through a high-frequency input. The built-in processor converts it into digital form and builds a spectrogram, displaying the distribution of signal power by frequency. The Waterfall function allows you to track signal changes over time. The built-in tracking generator creates a test signal for testing filters and amplifiers. You get a complete picture of the RF spectrum to fine-tune your equipment.
