5.7.2. Experimental DAC: recording signals from variously located
reflectors
Creating of experimental DAC is allowed upon theoretical DAC negated:
dB/mm = 0
(
dB/in = 0
). To create
/ modify experimental
DAC
click on
– the
Draw Gate
mode (
Draw A
) is active so it is possible to
manipulate
Gate A
over the entire
A-Scan
area
Recording 1
st
DAC echo
Place probe onto
DAC
calibration
block and maximize echo from the
reflector closest to the probe (first
echo) then place
Gate A
over
received signal and capture first
DAC echo
through click on
This leads to the recording of the
first DAC echo; the total number of
stored echoes is indicated
accordingly
To erase the last recorded echo
