The options that are available and the power of the product are amazing. We’ve solved more problems quicker with Observer than any other analyzing software we’ve had.

With the Observer Platform from VIAVI Solutions, we have been able to prove when it is (or isn’t) the network that is the problem. We can also help application programmers and system administrators understand and correct what the problem may be.
