TUNABLE SQUARE WAVE

PULSER – STANDARD FEATURE

The EPOCH 4 set a new industry standard

in 2001 when it was introduced with both a

Tunable Square Wave Pulser and a Negative

Spike Pulser. These high voltage pulsers offer the

operator extensive application versatility and

ease of use. The Tunable Square Wave Pulser

along with Narrowband ﬁltering produce class-

leading material penetration and signal-to-noise

ratios in difﬁcult materials such as cast metals,

large forgings, composites, and plastics.

Both pulsers are standard equipment on the

EPOCH 4PLUS, EPOCH 4, and EPOCH 4B,

and optional on the EPOCH LT.

920-005B

The Panametrics-NDT™ EPOCH 4 is

an advanced digital ultrasonic ﬂaw

detector that combines powerful, fully

featured measurement capabilities, a

comprehensive internal datalogger, and

a wide range of software options to solve

many demanding inspection problems.

Signal processing features include a 25

MHz bandwidth to permit testing of

thinner materials, a selectable square

wave pulser to optimize penetration

on thick or attenuating materials, and

narrowband ﬁlters to improve signal-to-

noise ratio in high gain applications. The

EPOCH 4 incorporates rugged packaging

and a conveniently organized direct-

access keypad, and offers the choice

of high-resolution Liquid Crystal or

Electroluminescent displays.

A large capacity datalogger allows ﬁeld

storage of test data that can then be

transferred to the PC via its versatile

GageView PRO Interface Program.

EASY AND FAST OPERATION

The EPOCH 4 with its robust packaging

design, large display, and functional

color-coded keypad provides easy and

fast operation in difﬁcult inspection

environments.

Important keys such as Gain, Freeze,

Save Thickness, Save Waveform, Enter,

and Slewing Keys are grouped together

for easy thumb control and one-handed

operation of all critical parameter

settings.

The ﬁve Function keys allow quick access

to preset parameter values that can be

customized by the operator.
