# Format:
#  DESC<tab>LOW HIGH TYPE SCALE UNITS
#   DESC	exact match or prefix of signal type (`desc') in header file
#   LOW		low value of calibration pulse, in physical units ('-': signal
#		  is AC-coupled)
#   HIGH	high value of calibration pulse if DC-coupled, peak-to-peak
#		  amplitude of calibration pulse if AC-coupled ('-': not
#		  defined)
#   TYPE	`sine', `square', or `undefined' (shape of calibration pulse)
#   SCALE	customary plot scale, in units per cm
#   UNITS	physical units of signal as in header file
# For further details, see dbcal(5).
