Table 2: Description of parameters
Parameter Description
Array mode Switches between linear or matrix device mode.
Analog gain,
dB
This parameter can be used to increase the analog signal
amplitude before it is being transformed into a digital signal by
A/D-converter. Analog gain is expressed in db. It is preferable to
apply the analog gain first since it extends the usage of A/D-
converter digital resolution. Decrease analog gain in case of
saturated signals.
Digital gain,
dB
This parameter can be used to increase the digital signal after it
has passed the A/D-conversion. Digital gain is expressed in db.
Digital gain does not improve digital resolution rather equally
amplifies both signal and noise. The parameter allows to improve
contrast of resulting images.
Operation
frequency,
KHz Sets frequency of excitation pulse on ultrasonic transducers.
Default frequency is 50KHz-
Filter
bandwidth,
KHz Digital filter bandwidth with central frequency equal to operation
frequency.
Show TGC Option to show/hide TGC curve on an A-Scan.
TGC, dB/µs Defines slope of analog TGC expressen in dB/µs
TGC delay, µs Defines zero-delay of TGC curve
Transmitter
pulse
sequence Defines number of half-periods for excitation pulse. Value 0.5,1,...
stand for 1 half-period, 2 half-period (or one period) etc.
18.2 Display parameters
