Working With Echo Max - GE USM 36 Series Technical Reference And Operating Manual

5 Operation

Working with Echo Max

The USM 36 usually produces more A-scans per sec-
ond (= PRF) than the display screen of the instrument is
able to show (= 60 A-scans per second). In this connec-
tion, the displayed A-scans are chosen at random from
the raw data.
With the function Echo Max turned on and with
PRF > 60 Hz, the USM 36 analyzes the raw data and
shows the maximum amplitudes at every one of the 800
single points.

– Switch to the second operating level.
– Select the function group CONFIG2.
– Select the function ECHO MAX and press one of the
selector keys to turn on the function.
Example
With a PRF of 1200 Hz and the function ECHO MAX
turned on, 1200/60 = 20 A-scans are analyzed as raw
data.
The highest amplitude at each one of the 800 single
points is displayed as a combined A-scan.
N o t e
With a PRF = 60 Hz and lower, no echo
maximizing takes place any longer.
