VG1 SAT PWS Edited Spectrum Analyzer: Voyager 1 Plasma Wave Data

16 spectrum analyzer channels measure electric field intensities from 10 Hertz to 56.2 kiloHertz. Voyager 1 Plasma Wave Receiver data was obtained in the vicinity of the Jovian magnetosphere, with measurements recorded at 4-second intervals. The National Aeronautics and Space Administration provides edited but uncalibrated data numbers for event searches and simple trend analysis.

Use Cases

• Search for plasma wave events based on 4-second interval electric field intensity scans.
• Perform trend analysis of wave intensity across 16 logarithmically spaced frequency channels.
• Study the structure of the Jovian magnetosphere using Voyager 1's in-situ measurements.
• Calibrate raw data numbers using the provided calibration procedures and tables.

Strengths

• Provides 16-channel frequency coverage from 10 Hz to 56.2 kHz, offering a broad spectral view.
• Data is edited for quality, with missing channels within a scan zero-filled for continuity.
• Calibration procedures and tables are provided alongside the raw data for accurate analysis.

Limitations

• Data gaps where complete 4-second spectra are missing are not zero-filled or tagged, creating discontinuities.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
