Transmit pulse
The transmit pulse consists of one or more electrical "shot" pulses, which are supplied to the
transducer connected to the device terminals. The transducer fires an acoustic "shot" for
each electrical pulse supplied. After each shot is fired, sufficient time is provided for echo
(shot reflection) reception before the next (if applicable) shot is fired. After all shots of the
transmit pulse are fired, the resultant echoes are processed.
The transmit pulse shot number, frequency, duration, delay, and associated measurement
range are defined by the following:
● Short shot frequency (2.1.7.) (Page 165)
● Long shot frequency (2.1.8.) (Page 165)
● Short shot duration (2.1.9.) (Page 166)
● Long shot duration (2.1.10.) (Page 166)
● Number of short shots (2.1.11.) (Page 166)
● Number of long shots (2.1.12.) (Page 167)
● Shot/pulse mode (2.1.17.) (Page 168)
● Short shot bias (2.11.2.10.) (Page 225)
● Short shot floor (2.11.2.11.) (Page 226)
● Short shot range (2.11.2.12.) (Page 226)
