Chroma
The echo am plitudes are converted to pixels with different brightness. The chrom a value (color
tone and saturation) is mapped to the pixels. There are 13 map combinations available.
The chroma value is adjustable in the real time mode as well as the freeze mode.
Instructions:
1.
Open the menu, and use the trackball to select
Chroma
.
2. Rotate
to change the chroma setting.
6.2.4
Frequency
The transducer is capable of generating a broadband signal with a certain start frequency and
a certain bandwidth. The higher frequency that is set, the higher the resolution, the lower the
penetration.
Instructions:
1.
Open the menu, and use the trackball to select
Frequency
.
2. Rotate
to change the frequency range.
NOTE:
The frequency range is displayed at the 2D Image Info area (as FRQ).
6.2.5
Acoustic Output Power
The acoustic output power of the transducer should be set t o the minimum value as long as
well-evaluable information can be provided. Always keep the power level and the exposure
time as low as reasonably achievable.
Instructions:
1.
Open the menu, and use the trackball to select
Power %
.
2. Rotate
to change the value of the acoustic output power.
NOTE:
The acoustic output power is displayed on the top left screen as
PWR
.
You can decrease the acoustic power indices (MI, TI) by reducing the output power of the
transducer.
