DATA_SET_TERSE_DESCRIPTION Analysis of variations in the amplitude, phase, and frequency of the signal provides information on the ring structure, atmospheric density, magnetic field, and charged-particle environment of planets which occult the spacecraft.
DATA_SET_DESCRIPTION
The DSP-R is a computer-controlled subsystem that digitally samples a
       received spacecraft signal (both X and S-band) through the
       use of four analog-to-digital (A-D) converters.
       The digitized samples, along with the monitor data
       necessary to reconstruct the signal, are recorded on tape, and/or
       transmitted in realtime to SFOC. Analysis of variations in the
       amplitude, phase, and frequency of the signal provides information
       on the ring structure, atmospheric density, magnetic field, and
       charged-particle environment of planets which occult the spacecraft.
       Additionally, this signal is needed for gravity wave detection.

       The DSP-R digitally samples the received spacecraft signal with 8-bit
       or 12-bit resolution and creates records of varying lengths, depending
       on the sample rate and resolution. Each record is composed of (1)
       a header containing information on system configuration, time-tagged
       receiver local oscillator values, etc., and (2) a block of digital
       data from the four A-D converters.

       Time Tag Offset

       The sampled data are later than the reported time tag by two intervals
       of the sample rate of a single A-D converter. This means that in each
       record the ADC data which corresponds with the time tag is the third
       set of ADC samples in the record, not the first set.
