Powerful Software Capabilities
EPOCH XT ASME III DAC
EPOCH XT B-scan and Floating Gate
Standard Software
Software Options
Dynamic DAC/TVG
Calculates signal amplitude as a percentage or dB level compared
to a DAC curve or a reference echo amplitude fixed with Time
Varied Gain. DAC versions include ASME, ASME 3, JIS, and Custom. Contains several key features including: dynamically adjustable DAC curves, switchable DAC and TVG views, (20% to 80%)
DAC/TVG, a flexible TVG table, and custom DAC warning curves.
B-Scan
Single value (thickness) based B-scan that allows fully encoded
or manual scans for corrosion monitoring. Simultaneous viewing
of an A-scan and B-scan is available. Operates in all test modes
including: TVG, Echo-to-Echo, and Floating Gate. Includes Floating Gate option.
CSC (Curved Surface Correction)
Corrects sound path information when using an angle beam transducer to circumferentially inspect a curved surface.
DGS/AVG
Flaw sizing technique that permits echo signals to be evaluated
using a DGS/AVG diagram associated with a particular type of
probe and material. The DGS/AVG diagram shows the relationship
among echo height, flaw size, and distance from the transducer.
Floating Gate
Gate option, which allows the operator to “float” Gate 1 and/or
Gate 2 at a selected height compared to a gated echo (–1 dB to
–14 dB). This feature is intended to allow more consistent, precise
readings, especially in Edge Detection mode. This option is included in the B-scan option.
AWS D1.1 & D1.5
Provides a dynamic reflector “indication rating” for various AWS
weld inspection applications. This allows for more efficient inspection by eliminating manual calculations.
EPOCH XT DGS/AVG
The AVG/DGS Binder, contains
a DGS diagram and specification
sheets for each angle beam, dual
element, and protective face transducers from the Olympus NDT
Atlas Transducers series. These
diagrams are printed on splash
and tear proof paper and housed in a six-ring binder.

Template Storage
Interface Gate
Template Storage
Allows on-screen comparison of a live waveform with a saved
reference waveform. Saved templates can be dynamically toggled
on and off with a single key press for fast waveform comparison.
Gain adjustment feature allows each saved template a unique
base gain for inspections requiring varying sensitivity levels. Excellent for spotweld analysis and other applications.
Interface Gate
Advanced Filters
The Advanced Filters option takes advantage of the EPOCH XT’s
unique digital receiver design and allows unprecedented filtering
flexibility. This option allows the EPOCH XT operator to choose
from 37 different filter settings. Specific performance improvements
from this option include:
• Performance improvement with low- frequency probes com-
monly used for inspection of composites and plastics.
• Improved initial pulse recovery with new DC coupled setups.
• Optimized broadband response from mid- to high-frequency
transducers.
• Use of very low frequency transducers (50 kHz to 100 kHz
range) for specialized applications.
This optional third measurement gate enables real-time tracking
of a variable interface echo in order to maintain consistent digital
measurements.
Backwall Echo Attenuator (BEA)
Attenuates the backwall echo of an inspected part using the
screen region defined by Gate 2. BEA is used to avoid screen saturation of the backwall echo to allow detailed flaw echo examination in the part region before the backwall while still monitoring
the backwall echo for drop-out or signal reduction.
API 5UE
Allows defect sizing according to API Recommended Practice
5UE. Uses the Amplitude Distance Differential Technique (ADDT)
to measure the size of potential defects during the proveup
process of OCTG pipe. The measurement process is simple and
repeatable since all ADDT variables are captured from a Peak
Memory envelope.

Extensive Documentation and Data Management Capabilities
GageView Pro®
The optional GageView Pro interface
program helps manage and format stored
inspection data. Data can be printed or easily copied and pasted into word processing
files and spreadsheets for further reporting
needs. The GageView Pro interface program
also allows the creation of a customized
database of identifier (ID) strings that can be
uploaded to the EPOCH XT. New features
include remote display of live EPOCH
XT screens on a PC, Live-Screen Capture
mode, database backup/restore, and multiview windows. The interface program is
fully compatible with the EPOCH LT, XT,
600 and 1000 Series.
