Van Allen Probe A, Electric and Magnetic Field Instrument Suite and Integrated Science, EMFISIS, WaveForm Receiver, WFR, Level 2 Data. Three Axis Electric Field (Eu, Ev, Ew) and three Axis Magnetic Field (Bu, Bv, Bw) Continuous Burst Waveforms at 35 kS/s.
The Continuous Waveform Burst Mode is very similar to the Waveform Burst with Spectral Matrices Mode in that it produces a standard Survey Set of Spectral Matrices based on a 0.5 s Waveform Capture every 6 s. In addition, this Mode captures Continuous Waveforms for 5.968 s between each 6 s Survey Data Set, leaving a 0.032 s Gap between successive Captures. This Mode can be operated continuously for fixed Durations up to several Minutes. Alternatively, it can be used in conjunction with Burst Quality Flags that retain the best N 5.968 s Captures (N ≤ 20) in a preset Time Interval.

The Magnetic Field Axes Calibration Coefficients are for all three Electric Field Axes Waveforms. The Coefficients are for Real and Imaginary Components and they should be applied in Frequency Space. Reference the Calibration Frequencies Variable, CalFrequency, for Center Band Frequency. The first Column contains Coefficients for the Real Component and the second Column contains Coefficients for the Imaginary Component.

Calibration Frequencies, to properly correct for Phase and Amplitude, the Calibrations should be applied in Frequency Space.
The Wave Power Data Quality Flag is calculated onboard. A Quality Factor is built by using one or more of the onboard Waves Space Weather Parameters to indicate Activity. The Space Weather Parameters reflect the Intensity in three Spectral Bands in both the Electric and Magnetic Channels of the Waves Instruments. These correspond approximately to the Lower Band Chorus and Upper Band Chorus, which are separated by one half of the Electron Cyclotron Frequency, and a low-frequency Band below the Lower Hybrid Frequency. The Wave Power Quality Flag can be used to capture the best Waveform Captures in a preset Time Interval.
