The Development Guide will provide the
process and instructions to guide the user
through installing the guest WBT APP
Development virtual machine onto a host
system (such as Windows). From here, the
user will log into the Linux system to compile,
and run an example WBT Extension
application.
The WBT architecture has been designed with
an Open Framework Philosophy. The API
extensions are open for all to use and provide
everything but the most basic hardware
control and synchronization.
QRC Technologies is fully committed to
creating a WBT product that is fully extensible
to meet a multitude of test and measurement
needs in the market.
We welcome requests from industry on how to
extend the API to make it more useful to
accomplish specific user needs and will continue
expanding the API as needed to enable more useful
capabilities to the developer community.
Now is the time…
A Getting Started with QRC WBT App
Development Guide is provided…
