With VScope™, engineers and even system operators can scan received data from within the IC itself in a manner similar to oscilloscopes and bit error rate detectors. Offered in clock and data recovery products from Vitesse, VScope can operate on any channel of live data, enabling unique capabilities for testing and system monitoring. See below for more information on this Oscilloscope on a Chip technology.
VScope makes accurate monitoring possible that was formerly out of reach. By scanning a signal after the IC equalization but before conversion to a digital stream, a true picture can be obtained of the input signal and the equalization performance.
Remote scanning is another VScope advantage. By transporting the scan data in the packet overhead, this diagnostic information can be accessed in real time from anywhere in the network. Data service providers can make detailed remote measurements of signal integrity from the central office, eliminating on-site service to perform the same test using conventional instruments.
VScope diagnostics go beyond standard capabilities and enable revolutionary new applications. The technology augments design testing, and also creates opportunities for remote diagnostics and monitoring of ongoing system health. Free of the limits imposed by an external—and costly—oscilloscope, design engineers can access and share the waveform scan data through a simple controller interface.
