VIS - modular test electronics

The name VIS stands for new modular

test electronics for use in ultrasonic test

systems. Set up on VME bus basis, the

electronics is designed as 19" plug-in

module. A maximum of twelve channels

can be operated per ultrasonic module

and a maximum of five modules in a

system.

The parallel operation of all channels

with 20kHz PRF per channel enables a

very fast online inspection.

The electronics is completely operated

via the PC; Windows NT is available as a

user-friendly operating system. The sys-

tem provides a fully digital echo display

with a high-resolution A-scan, plus a

hardware-based compression

of the individual A-scans (EchoMax

function). This function ensures that

even a short-term event (single shot) will

not be "overlooked".

The test results (amplitudes, time of

flight) are available as 8- or 16-bit

information at the interfaces.

Main fields of application of the VIS

system:

• weld inspection

• tube testing

• quick online testing
