5.8 Settings (Admin Mode)
is section describes the settings that are only available to the Admin user. ey are only
visible if you login as the Admin user.
5.8.1 Waveform
Supersampling – e base sampling frequency is 66.6 MHz; supersampling is a multiplier
that allows you to increase the sampling frequency (i.e. if supersampling is set to three
the sampling frequency is tripled).
Averaging – is is a signal processing technique that reduces the amount of noise; mul-
tiple scans are taken and the average over the scans is used.
Inter-pass delay – Allows you to change the time delay between averaged scans.
5.8.2 Adjust Signal
To aid in setting these parameters a grid of transducer elements and an A-scan window is
shown. Clicking on a transducer element will cause the signal from that element to populate
the A-scan window.
Delay – controls the data acquisition delay. en you change this parameter, the entire A-
scan curve is shied in the A-scan window. A properly calibrated tool must show the
front surface reflection within the gates (green area in A-scan window).
Gain – controls the amplitude of the signal. e signal should be adjusted so that the peaks
are close to the horizontal lines connecting the gates (green area in A-scan window).
Range – controls how much of the signal is shown in the A-scan window.
