PCI - PC Ultrasonic
Testing Card
OPCON-01/100
|
| |
|
|
| |
OPCON-01/100 is particularly well
suited for ultrasonic measurements as well as other kinds of
measurements which employ multiplexed channels (the card is capable of
controlling such devices). Together with Pulser & Receiver OPGUD-01
or Pulser & Receiver OPGUD-Ex and ultrasonic probes it could be used
as complete ultrasonic testing device. OPCON-01/100 is a short PCI card
and can be installed in a standard PC.

| Characteristic
of the card: |
One of the most important features of the card is a precise
synchronization between the transmitter trigger signal T_NAD and the
moment when the sampling of the input signal starts.
This time (t_pom) is software programmable in the range of 0 - 255us
with a resolution of 1us and has stability within the range of 1ns. It
is particularly important in the case of scanning devices, since it
allows to achieve a very small time skew between different positions (channels).
1ns would correspond to a clock frequency of 1GHz which is much higher
than the actual frequency used.

Automatic measurement mode |
|
|
| Additional
notices |
In the current version of the card, there
is no analogue trigger input and this function is implemented in
software.
The card is programmed through the memory operations.
Thanks to the feature which allows the base address change, a number of
our cards can work in a single computer.
All the control signals generated by the card can be modified according
to specific customer requirements.
