ABSTRACT OF THE DISCLOSURE Test features are incorporated in an improved cableless seismic digital recording system recorder. The improved recorder facilitates application of earlier cableless seismic digital recording systems to situations in which seismic-trace data is generated by low energy surface seismic sources, such as vibrators and hammers. A seismometer, or geophone, is connected to a remotely deployed radio-controlled portable recorder which contains circuitry for sampling, digitizing, processing, storing, and recording seismic-trace data. Coded radio signals instruct the recorder to commence an operation or sequence of operations from a predetermined set of programmed instructions stored in program read only memory included in the recorder. Such operations include data acquisi- tion; optional weighting and vertical stacking (summing); normalization; recording; and seismic source initiation. Test features include control panel display of operational status and verification of gain-ranging amplifier opera- tion.
