Pulser Type

The EPOCH 650 operates in two pulser modes that you can select using the Pulser
parameter of the Pulser mode:
Spike
Used to mimic a traditional spike pulse by using a narrow-width pulse to excite
the transducer.
Square
Used to tune the width of the pulse to optimize the response of the transducer.
The EPOCH 650 uses the PerfectSquare technology to achieve optimum response
from the tunable square wave pulser. This PerfectSquare technology maximizes the
energy used to drive the connected transducer while providing excellent near-surface
resolution.
To adjust the pulser waveform
 Select Pulser > Pulser, and then vary the setting.
