The EFW Burst Modes provide targeted Measurements over Brief Time Intervals of 3-D Electric Fields, 3-D Wave Magnetic Fields, and Spacecraft Potential. There are two EFW Burst Modes: BURST1, B1, Medium-Rate 512 samples/s nominal and BURST2, B2, Higher-Rate, 16384 samples/s nominal. The Burst 1 Mode Data includes three components of the Electric Field, E12_B1, E34_B1, and E56_B1, six Components of the Spacecraft Sensor Potential, V1_B1 through V6_B1, and three Components of the AC Magnetic Field, SCM_U_B1, SCM_V_B1, and SCM_W_B1, from the EMFISIS Search Coil Magnetometer. The Burst 2 Mode Data returns a similar Complement of Electric Field, E_12ac_B2, E34ac_B2, and E56ac_B2, Search Coil, SCM_B2, SCM_2B2, and SCM_B2, again from the EMFISIS Search Coil Magnetometer and Single-ended Potential Measurements, V1ac_B1 through V6ac_B2, with the exception that in the Default Mode the Single-ended Potential and Electric Field Signals are AC coupled with a higher Gain. All Quantities are in UVW Coordinates where, U, and, V, are the Sensor Coordinates rotating with the Spacecraft and, W, points along the Spacecraft Spin Axis. Burst Waveform CDF Files are available. The three Data Types available are the Electric Field, E, the Searchcoil Magnetic Field, MSC, and Antenna Potential, V. The Suffix on each of these is either, B1 or B2. B1 or Burst 1 is the Human-in-the-Loop Burst Type, meaning that both Collection and Playback for arbitrary Lengths of Time are requested on the Ground. B2 or Burst 2 is automatically telemetered as short Bursts based on an onboard Triggering Algorithm, typically set to trigger on large Amplitude Signals near 1 kHz. Sample Rates for B1 and B2 can and are changed depending on varying Science Goals.
