Spectrograms, frequency spectra & time series from the Plasma Wave Subsystem (PWS)
| Band | Range | Source |
|---|---|---|
| Low-freq Turbulence | 10 – 100 Hz | Alfvén / ion-cyclotron waves |
| Plasma Frequency | 1 – 5 kHz | Langmuir / electron plasma oscillations |
| Upper Hybrid | 10 – 50 kHz | Upper hybrid resonance |
10 Hz to 56.2 kHz using a 10-m dipole antenna.
It detects Langmuir waves, whistler-mode emissions, and electron plasma oscillations critical for probing the interstellar medium.
