The PSM-500/4900 does not have an analog test point to view the eye pattern. All information at this point in the receive chain is digital and measured by the modem processor. The result of this measurement is presented as the Eb/No. If it is absolutely essential to view the eye pattern as analog test information, contact the factory for availability of a special test fixture for conversion.
