SPECTRA Test Utility

The SPECTRA Test Utility was created during development of the interface to allow the majority of its features to be tested and analysed. As software support increases for the SPECTRA display modes, the usefulness of most of these test facilities declines. However, some tests, such as those for the RS232 socket, may still prove of use and so the test utility continues to be made available.
