Features of the XU-2468:

· Large EL display


· Fast and easy Test Setup
  - Direct access keys and  three quick  knobs allow immediate changes of
     multiple  functions.


· On Line Help
  makes manual nearly obsolete.


· Digital Single Shot Peak Detection
  can accurately  detect & measure a flaw each rep, at a rep rate of 24 kHz.

The XU-2468 is an eight channel flaw detector and thickness gauge incorporating an electroluminescent waveform display panel. Its high-speed systems capability, coupled with its user-friendly design make the XU-2488 the best choice.

The XU-2468 is ideally suited for high-speed systems application. Digital Single Shot Peak Detection enables the instrument to detect and measure a flaw in one rep. This, combined with a rep rate of 24 kHz, results in unparalleled high-speed testing.

Four gates are incorporated into the XU-2468 to provide unmatched flexibility and economy. Flaw detection, thickness detection, surface following, back following and back echo attenuation capability are all provided

Each channel can be individually set to operate as a flaw detector or thickness gauge. If a channel is set to flaw detect then Gates 1-4 can be enabled as flaw detectors. If a channel is set to thickness detect then Gate 4 is a Hi-Res thickness gauge with a resolution of ±.0001". Gate 1 can always be used as a surface detector for any gate set to surface follow.

The large 4.5 × 3.4 display screen provides an uncluttered view of the waveform. Four measurements and three Quick Knob functions are visible without interrupting the waveform display. A pop-upcursor enables quick setup of ultrasonic tests and provides measurements of tests and provides measurements of both thickness and amplitude.

All Xactex keys and functions are straightforward and indicated with clear, concise text-no confusing graphics. Large, legible characters are used for all measurements and instrument settings.

Testing can begin quickly with the XU-2468, Direct Access Key (such as PULSER/RECEIVER, GATE1-4 and RANGE) require only a single key stroke for immediate adjustment of multiple instrument functions using the three Quick Knobs.

Once a Direct Access Key is pressed, the most commonly adjusted functions appear above the three Quick Knobs and a pop up Function Menu appears in the upper right hand corner. The left and middle Quick Knob are reserved for controls which are frequently changed. You can select any control from the Function Menu and adjust it with the right Quick Knob using the Menu Select Keys. The pop up menu disappears at the touch of a key, so your waveform display remains uncluttered.

A user-defined Key, MY MENU, can be set up by the operator to access the three functions most often used in a test.

If you have any questions you do not need to search for your manual. Press the Help key and a pop up window immediately displays a description of the function you are adjusting.

The advanced design and performance of the XU-2468 provides high-speed testing without complicated setup procedures. So you can concentrate on your testing... not an instruction manual.

Eight-Channel Multiplexed Flaw Detector

The XU-2248 can on any rep : Fire any one of  8 pulsers
                                                         Listen with any one of  8 receivers
                                                         Store the result in any of 16 gates

High speed RS-485 serial links give fast, reliable data/control from external controller

Integral multiplexer improves system performance


The XU-2248 is an 8-channel multiplexed ultrasonic flaw detector. It uses the newest technology for the 8 pulsers, 8 receivers and 16 gate channels incorporated into the XU-2248. 
The many interfacing options available to an ultrasonic system developer permit the XU-2248 
to be integrated into the virtually any computer-controlled test system.
A variety of data reduction algorithms, incorporated into the XU-2248, 
substantially reduce the data that must be transmitted to the system controller. 
They also reduce the system overhead.
 
The XU-2248 provides an improved, coat-effective alternative for for multiplexed systems.
Traditionally, a multiplexed system "patches" together an external multiplexer and a conventional
flaw detector and the multiplexer are often not well matched. 
Since an external multiplexer replaces the most important part of the flaw detector, 
it may compromise the system performance of an otherwise good flaw detector.
 
Front panel controls on the XU-2248 allow for a very wide range of applications in ultrasonic 
test systems. The Damping and width of each pulser are individually adjustable, and the 
operator can choose pulse-echo or pitch-catch operation for each pulser, as well. 
The rep rate is adjustable from 100 Hz - 10 kHz and is shared among all of the channels.
  
The Gains of each receiver amplifier are fully adjustable, individually. 
In addition, a common Gain control provides for rapid adjustment of all of the channels together,
as does Reject and Frequency. Tying two receiver inputs together provides separately (the example system uses this idea to get separate gains for pulse-echo and pitch-catch operation). 
The XU-2248 output is monitored by an external oscilloscope.
 
The 16 gate channels each have a separate Alarm Output and Peak Detector. 
Alarm LED's on the front panel give a visual alarm indication. The peak detected output from 
any gate channel (selected from the front panel) can be applied to the Analog Output on the 
rear panel. All of the peak detector outputs are available to a system controller over the high speed serial link. Alarm Filters for each of the gate channels are separately adjustable 
and allow the XU-2248 to be used in noisy industrial environments without generating spurious
alarm indications that would slow system test throughput.
 
In addition to these individual gate controls, the XU-2248 allows a gate to be re-positioned 
on every rep. These gate controls include Blanking, Delay, Width and Alarm Level.
Thus, the reps assigned to be a particular Gate Channel may have many gate positions 
and Alarm Levels.
 
Flexible triggering controls permit the operator to trigger an external oscilloscope on (and thus View) any individual rep, when any particular pulser fires, when any particular receiver "listens", 
or when any particular gate channel is used. The operator can also program the XU-2248 
to trigger on an arbitrary group of reps.
 
Using the concept of cyclic operation, pioneered by Xactex in the XU-2248 Flaw Detector, 
the XU-2248 can generate complex, cyclic test sequences. 
These test sequences can be programmed from the instrument front panel or input from an
external IBM -compatible PC, using the  UT-QWIK software supplied with the XU-2248. 
On any given Rep in the cyclic sequence, the XU-2248 can fire any one of the 8 pulsers,
"listen" with any one of the 8 receiver amplifiers, and apply the results to any one of the 16 gate channels. One possible sequence is illustrated for a common weld test system by the accompanying Figure and Table.
 
This system uses two parts of transducers. 
Each transducer in a pair is "aimed" at its mate, making pulse-echo and pitch-catch operation possible. The inputs of two receivers are tied together, which allows separately adjustable gains
for pulse-echo and pitch-catch operation. 
Referring to the table, which displays the programming of the rep sequence, 
the first four reps are pulse-echo tests involving all four transducers. 
The next four reps execute a pitch-catch test between transducer pairs to check coupling.
Note that the "results" of the coupling check are all applied to Gate 1, though they could be
applied to four additional gates, if desired. Reps 9-12 and 13-16 are repeats of reps 1-4. 
This Table illustrates a 16-rep sequence that will repeat during the next 16 reps and continue repeating as the test progresses. 
Sequences up to 128 reps can be programmed, stored and recalled by the XU-2248.
