What is the maximum pulse length?
The pulse length is 30% of the range to bottom. For example, 30% of 200m = 60m yields a maximum pulse length of (60*1.57 = 94.2 ms). It should be noted that when the range to bottom equals or exceeds 50% of the BX command value entered then the transmit pulse length is limited to 15% BX. The pulse length may be modified if necessary. However reductions in pulse length may effect the Navigators ability to reliably bottom track some seabed materials / conditions.
