13.8.3 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, to prevent
detection of trailing lobes or cycles of that echo and the resulting gage hang-up (see
Figure 13-16 on page 239).
