Owon HSA2307 - EMI Spectrum Analyser - Oscilloscope - Precision Multimeter

The Owon HSA2000 Series is a consolidated measuring solution for the industrial environment. By integrating a spectrum analyser, a dual-channel oscilloscope, and a high-precision 4½ digit multimeter into a single 600V CAT III chassis, it addresses the specific operational friction of diagnosing complex EMI and power quality issues in the field in a practical and economic package.

In industrial automation, the 'crime scene' is usually a crowded VSD cabinet or a noisy plant floor. Carrying a benchtop spectrum analyser is impractical, and a standard multimeter lacks the bandwidth to observe the issues. The HSA2000 fills that gap - affording electrical, time-base, and frequency base measurements.

EMI Investigation & Leakage Current Diagnostics

Modern Variable Speed Drives (VSDs) and other power electronics are notorious for generating common-mode leakage currents that wreak havoc on analogue instrumentation, digital communications, and can cause false-triggering of emergency stops. When paired with an external current clamp (such as the Owon CP024), the HSA2000 allows for high-fidelity analysis of these currents. When paired with near-field EMI probes, it allows for EMI sniffing. In an industrial environment a low-frequency H-field  (magnetic field) probe is a must-have.

• Frequency Domain (Spectrum): Identify harmonic clusters and switching noise peaks from 9 kHz up to 3 GHz.
• Time Domain (Oscilloscope): Observe the exact pulse-width modulated (PWM) waveform and transients causing insulation stress.
• EMI Sniffing: Use near-field probes to locate radiated interference from poorly shielded cables or failing components before they trigger a plant-wide outage.

Multimeter with 20,000-Count Precision and 600V CAT 3 Safety

The HSA2000 features a 4½ digit (20,000 count) DMM. This resolution is critical for industrial technicians calibrating 4-20 mA analogue loops, testing PT100 temperature sensors, or detecting the subtle voltage drops in DC control circuits that indicate high-resistance terminations.

Operational Workflow & Documentation

Fieldwork is only as good as its documentation. The HSA2000 provides dedicated internal storage slots for instant data capture and ease of configuration changes. There are dedicated storage arrays for the Spectrum Analyser and Oscilloscope operating modes.

• 4x Configuration Slots (.BIN): Instantly recall complex trigger and scale setups for repetitive testing.
• 4x Data Slots (.CSV): Export raw waveform data for post-incident analysis in Excel or Matlab.
• 4x Image Slots (.BMP): Capture screen evidence of anomalies for maintenance reports.

Technical Specifications

Connectivity & Expansion

The unit supports two distinct USB modes. HID Mode allows for real-time remote control and monitoring via the included Owon software suite—ideal for monitoring intermittent faults from a safe distance. MSC Mode treats the device as a standard storage drive for rapid file transfer.

Configuration Note: For the ultimate portable diagnostic kit, we recommend pairing the HSA2000 with the Owon CMS—a Bluetooth-enabled clamping scope meter. This combination allows you to monitor primary current waveforms on your mobile device while performing high-resolution spectral analysis on the HSA2000.
