Advanced Conventional Ultrasound

Upgradeable to Phased Array

The EPOCH® 1000, EPOCH 1000iR, and EPOCH 1000i
provide advanced conventional ultrasound capabilities
for both basic and advanced level users. These portable
instruments can also be integrated into small systems for
high speed scanning and single‑ channel imaging and
come standard with a host of high performance features,
including a 6 kHz maximum Pulse Repetition Frequency
(PRF) with single‑shot measurements for accurate high‑
speed scanning applications, tunable square wave pulser
with PerfectSquare
tal filter sets for exceptional signal‑to‑noise clarity.

Pulser/Receiver Features

• Adjustable pulse repetition frequency (PRF):

5 Hz to 6 kHz.

•

Single‑shot measurements in all standard modes.

• Tunable square wave pulser with PerfectSquare™

technology.

Standard Software Features

Dynamic DAC/TVG Mode Interface Gate with Gate 1 and Gate 2 Tracking

• Dynamic DAC/TVG – This standard feature enables fast and

dynamic creation of DAC curves using reference reflectors, in
addition to single‑button switching from DAC to TVG mode.
Includes ASME, ASME‑III, JIS, 20% to 80% DAC, Custom, and
TVG Table.

• Onboard DGS/AVG – The DGS/AVG flaw sizing technique

uses calculated attenuation curves to aid you in sizing
potential defects. A vast onboard library of characterized
probes enables you to quickly and easily setup a DGS/AVG
curve and perform precise flaw sizing.

• Interface Gate – This optional third measurement gate enables

real‑time tracking of a variable interface echo in order to
maintain consistent digital measurements.

• AWS Welding Rating – This weld rating calculator provides a

live AWS D1.1/D1.5 code‑compliant “D” value weld rating for
gated flaw indications.

• Floating Gate – This option enables you to “float” Gate 1 and/

or Gate 2 at a selected height compared to a gated echo (–1
dB to –14 dB). This feature provides more consistent, precise
readings, especially in Edge Detection mode.

ClearWave™ Conventional Ultrasound Visual Enhancements

SureView Screen

The EPOCH® 1000 series features a new and exciting set of visual
enhancement capabilities to improve the quality and ease of
detection in advanced applications.

• SureView

®

– This feature emulates the functionality of analog
CRT displays, allowing you to visualize peak indications from
reflectors by adding a point of light along the A‑scan trace
where every peak occurs.

• Composite A-scan –

This feature uses every A‑scan acquired
in between screen update rates (multiple A‑scans when
PRF > 60 Hz) to draw a composite A‑scan based on the
maximum envelope of all the acquired A‑scans. This feature
increases confidence of visual detection when scanning
quickly.

• Max Amplitude – This feature displays only the acquired

A‑scan with the highest gated amplitude reading between
screen updates.

Persistence Mode Screen

• Persistence Mode – This feature retains previously acquired

A‑scans on the instrument display for a user‑selectable
duration. This feature provides visual “memory” of an
inspection for enhanced visual detection over a short period
of time.

• Baseline Break

– This feature displays “zero‑cross” points as
lines connecting individual A‑scan lobes to the baseline in full
‑wave rectified mode.

• Min Thickness – This feature displays only the A‑scan

representing the minimum thickness reading between screen
updates.

• Averaged A-scan – This feature enables you to view the

average of the acquired A‑scans. Averaging is applied in
multipliers of 2x, 4x, 8x, 16x, 32x, and 64x.
