Fixed delay (ms):
Additional time that is independent upon depth (e.g. processing
time). Range is 0 – 60,000 ms.
If both values are set to 0, then the active period will simply be the round trip time
of a normal incidence sounding at current depth. Runtime parameters are unique for
each profile, so it is possible to set up different parameters depending on the specific
requirements of the survey.
Fixed period mode

Runtime settings dialog - Fixed period
When using fixed period trigger mode, only the period can be specified. Ready to
transmit signal will be ignored for timing purposes (if provided). This setting is preferred
when the active period does not vary directly based on current depth (may be particularly
suitable for acoustic Doppler current profilers).
