OWON HSA2000 Handheld Spectrum Analyzer up to 3GHz

The OWON HSA2000 Series combines a spectrum analyzer, 2-channel digital oscilloscope and 4.5-digit digital multimeter in one handheld instrument. With spectrum analysis from 9kHz to either 1.5GHz or 3GHz, the series supports portable RF investigation, interference troubleshooting and electronic signal measurement in laboratories and at field locations.

Integrating frequency-domain analysis, time-domain waveform inspection and standard electrical measurements reduces the amount of equipment technicians need to carry. The compact format is particularly useful for RF engineers, electronics developers, maintenance technicians and educational laboratories that require several diagnostic functions at the same worksite.

Key Features

• Three measurement functions in one instrument: Switch between spectrum analysis, oscilloscope measurements and multimeter testing without carrying three separate devices.
• Spectrum analysis up to 3GHz: Inspect frequency components, harmonics, spurious signals and interference across RF and electronic systems.
• 100Hz frequency resolution: Set and evaluate frequency positions accurately when examining closely spaced signals or narrow frequency changes.
• Zero-span analysis: Observe signal amplitude behavior over time at a selected frequency for modulation and intermittent-signal investigation.
• 2-channel digital oscilloscope: Compare two time-domain signals when debugging control circuits, power electronics and embedded hardware.
• Up to 1GSa/s oscilloscope sampling: Higher-series models provide faster acquisition for inspecting shorter signal transitions and higher-frequency waveforms.
• Peak acquisition and automatic measurements: Capture signal peaks and measure parameters including frequency, period, RMS, rise time, fall time and pulse width.
• Up to 10,000wfms/s refresh rate: Rapid waveform updates improve visibility of changing or intermittent signal behavior.
• 4.5-digit digital multimeter: Measure voltage, current, resistance, capacitance, diodes and continuity during electrical troubleshooting.
• USB Type-C PC communication: Connect the instrument to compatible OWON PC software for data handling and extended analysis.
• Handheld battery-powered design: Perform RF and electronic measurements at equipment installations, service locations and other sites where benchtop instruments are impractical.

Applications

• RF signal detection and spectrum monitoring
• Interference, harmonic and spurious-signal troubleshooting
• Wireless equipment inspection and field maintenance
• Embedded-system and electronic circuit debugging
• Time-domain waveform comparison
• Voltage, current, resistance and continuity checks
• Laboratory measurement and electronics education

Why Choose the OWON HSA2000 Series?

The HSA2000 Series provides a practical measurement platform when both RF and general electronic troubleshooting are required away from a fixed test bench. The HSA2105 is suited to applications that remain within the 1.5GHz spectrum range. The HSA2307, HSA2310 and HSA2320 extend spectrum analysis to 3GHz, making them more appropriate for higher-frequency RF investigation. Within the 3GHz group, the required oscilloscope bandwidth should be selected according to the fastest time-domain signals being measured.
