Pulser Frequency Selection (Pulse Width)
The pulser frequency selection sets the pulse width when
1/5 > Pulser > Pulser =
Square
. This frequency selection allows you to tune the shape and duration of each
pulse to obtain the best performance from the transducer being used. In general, the
best performance is achieved by tuning the pulser frequency as close as possible to the
center frequency of the transducer being used.
To adjust the pulser frequency
Choose
1/5 > Pulser > Frequency
, and then vary the setting.
Actual results could vary due to the test material and/or variation in the
transducer center frequency. Try various settings with a transducer and test piece
to maximize ultrasonic performance.
