Adjusting the Pulser/Receiver (Conventional UT Mode) 95
To compensate for the one-way sound path in through transmission (Thru) mode,
the EPOCH 1000 Series does not divide transit time by two when calculating
thickness measurements.
To adjust the test mode
Choose 1/5 > Pulser > Mode, and then vary the setting.
4.4.5 Pulser Waveform
The EPOCH 1000 Series conventional ultrasound mode operates in two pulser
waveform modes that you can select using the 1/5
> Pulser > Pulser parameter:
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 1000 Series 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
Choose 1/5 > Pulser > Pulser, and then vary the setting.
