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.
