    SLIFER Decipher

    The SLIFER Decipher (SD) is a digital instrument that records a time-varying frequency signal in the range from 700 kHz to 1500 kHz with an amplitude greater than 200 mV. This signal is referenced to an input fiducial marker. The primary purpose of this instrument is to reduce data recorded on magnetic tape from the SLIFER system used in underground nuclear tests. The SD records 512 samples after the fiducial signal, with a sample interval of 50 ..mu..s (for a total recording time of 25.55 ms). The measurement essentially uses a 20-cycle period-averaging counter technique

    The Digital SLIFER Recorder (DSR) is an instrument that records a time-varying frequency signal in the range from 700 kHz to 1500 kHz with an amplitude greater than 200 mV. This signal is referenced to an input fiducial marker, and recording is initiated by an increase in the frequency of the signal. The primary purpose of this instrument is to record data from the SLIFER system. The DSR records 512 samples after the record trigger signal, with a sample interval of 50 ..mu..s (for a total recording time of 25.55 ms). The measurement essentially uses a 20-cycle period-averaging counter technique
