Includes FAST SURVEY, PARTICLE BURST and WAVE BURST data. FAST SURVEY (SCF): 1/8 second time resolution. PARTICLE BURST (SCP): 1/128 second time resolution; only short bursts of data. WAVE BURST (SCW): 1/8192 second time resolution; only short bursts of data. Sensor and electronics design provided by LPP, Roux and Le Contel. SCM Telemetry Modes (Only first 3 apply to level 2 SCM products): +-------------------------------------------------------------------------------------------------------------------------+ | Fast Survey (scf) | Waveform data for the 3 SCM components; sampling rate between 2 and 256 S/s, nominal value is 8. | | Particle Burst (scp) | Waveform data nominally at 128 S/s. | | Wave Burst (scw) | Waveform data nominally at 8192 S/s. | | Filter Bank (fbk)^ | Mean signal value over 6 frequency bands (4-2 kHz, 1-0.5 kHz, 256-128 Hz, 64-32 Hz, 16-8 Hz. | | Particle Burst Spectra (ffp)^^ | Compressed FFT spectra in 16, 32, or 64 frequency bins; sampling between 1/4 to 8 S/s. | | Wave Burst Spectra (ffw)^^ | Compressed FFT spectra in 16, 32, or 64 frequency bins; sampling between 1/4 to 8 S/s. | +-------------------------------------------------------------------------------------------------------------------------+ * ^Only two available inputs between all 3 SCM and 12 EFI data signals. * ^^Only four available inputs between 3 SCM and 16 other data signals.
