Mode 3 Echo Blank
The echo blank in mode 3 (
M3 BLANK
) is similar to the interface blank in mode 2, or
to the main bang blank in mode 1. This function creates a blank or dead zone up to
20 µs long following the leading edge of the first detected back-wall echo in order to
prevent detection of trailing lobes or cycles of that echo, and the resulting gage hang-
up (see Figure 10-16 on page 182).
