Standard DAC/TVG for All Focal Laws
The EPOCH 1000i comes standard with DAC/TVG for all focal
laws. This allows you to acquire a DAC curve, or create a TVG
setup from known reflectors for all defined angles/focal laws at
once. The instrument then allows you to edit individual points
acquired during setup for precise DAC or TVG presentation. After
completing the setup, you can use the S‑scan image to detect
potential defects at various focal laws.
Standard Phased Array DGS/AVG
The DGS/AVG flaw sizing technique is included as a standard
option in phased array mode. This feature uses the probe ID and
wedge information to establish the DGS/AVG curve characteris‑
tics, and applies the curve at 0°, 45°, 60°, and 70° focal laws. The
standard EPOCH onboard DGS/AVG menu and modified GAIN
calibration tool allow for quick and easy setup. The option also
provides an interpolated image TVG for easy detection across a
given soundpath range.
