10.8 Echo Window
The echo window is the time interval after each main bang, during which the
instrument is enabled to detect echoes. The echo window interval begins at the end of
the main bang blank. The echo window ends at
x
µs following the main bang in
mode 1, or at
x
µs following the interface blank in mode 2 and mode 3.
In mode 1, you can usually set the echo window to any value greater than the round-
trip pulse transit time in the thickest or slowest piece of material to be measured (see
Figure 10-11 on page 178). The exact setting is not critical as long as it is long enough
to include the farthest echo of interest.
