Voyager 1 PWS: Uncalibrated Electric Field Waveform Data for the Full Mission

The Voyager 1 Plasma Wave Subsystem (PWS) electric field waveform data set contains all available uncalibrated full resolution 4-bit measurements for the entire mission. The waveform receiver samples voltage on the 10 m electric antennas at 28800 samples per second through a 40 Hz to 12 kHz bandpass filter. This data was produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Identify transient events like dust impacts based on time-domain waveform features mentioned in the description.
• Derive relative power spectra to analyze the amplitude of spectral elements in the frequency domain.
• Study plasma wave behavior and antenna response using the high-resolution 4-bit waveform samples.
• Investigate signal characteristics within the instrument's 40 Hz to 12 kHz bandpass filter range.

Strengths

• Contains all available uncalibrated full resolution measurements for the entire Voyager 1 mission.
• Data is sampled at a high rate of 28800 samples per second.
• Waveform data is captured through a specific 40 Hz to 12 kHz bandpass filter.

Limitations

• Absolute calibration cannot be performed directly as gain information is not returned in telemetry.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
