Eye - SDI in A [SDI Modes]
PHQX01E / PHQX01E-IP / PHQXM-01E]
One of the unique features of the Qx is the PHYSICAL layer analysis toolset. The Qx contains fundamental
technology developed and patented by PHABRIX which makes it unique where physical layer compliance
measurements are required up to 12 Gbps.
The Qx employs an analog front end providing in excess of 30 GHz bandwidth (5th harmonic of the 6GHz
fundamental for 12G-SDI). Featuring PHABRIX RealTime Eye RTE™, the Qx provides broadcast engineers
with a reliable, instantaneous physical layer display with automatic measurements to SMPTE standards.
The Qx enables measurement of both overshoot and undershoot along with amplitude, rise time, fall time
and delta - compulsory when testing against SMPTE standards. Accurate measurements are obtained within
seconds of connecting an SDI signal, making for a very fast system testing solution. Out of specification
measurements are indicated in red.
Example 1: 12G-SDI Eye pattern display with 100 kHz jitter filter
Example 2: 3G-SDI Eye pattern display with 100 kHz jitter filter
Note: ‘SDI In A’ has a red nut to indicate it is the SDI BNC that has the eye and jitter circuitry behind it
Note: The use of SFPinputs with the ‘Eye - SDI In A’ toolset is not supported
