Parker Solar Probe FIELDS DFB: Search Coil Magnetometer Burst Waveforms

Burst waveform data from the Digital Fields Board (DFB) on the Parker Solar Probe spacecraft, calibrated for in-band gain and filter responses. The data contain voltage measurements in Volts and magnetic field measurements in nT, with a sample rate that can reach 150,000 samples per second during solar encounters. This Level 2 product is provided by NASA and was last updated in March 2026.

Use Cases

• Analyzing high-frequency magnetic field fluctuations based on search coil magnetometer (SCM) data in nT units.
• Studying plasma wave phenomena using calibrated differential voltage sensor data in Volts.
• Investigating solar encounter dynamics based on data collected within 0.25 AU of the Sun.
• Developing signal processing algorithms for spacecraft data based on described analog and digital filter calibrations.

Strengths

• Data are calibrated for DFB in-band gain, analog filter response, and digital filter phase response.
• Sample rate during solar encounters is specified as 150,000 samples per second.
• Data provenance is clearly documented with references to peer-reviewed instrument descriptions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Corrections for plasma sheath impedance and antenna effective length are not applied in this Level 2 product.
• Row count and dataset size are unknown, which may limit suitability assessment.
