Page 5 The same video signal is digitally encoded to composite video and converted to analog form to drive the Analog Composite output. BrightEye 55 is powered by a 12 volt DC universal power supply. This power supply can accept an input voltage between 90 and 230 volts, at 50 or 60 Hertz. It uses a standard IEC line cord and can be used anywhere in the world.
Page 6 As shown in the example below, a BrightEye 55 is fed with the house reference to the Ref In BNC. The audio tone can be embedded into the SDI timed test signal output and fed to an SDI router and switcher.

Page 9: Operation
BrightEye 55 OPERATION Control and operation of the BrightEye 55 is performed from the front panel and with the BrightEye Control application. Some control settings and parameter choices are only available with BrightEye PC or NOTE Mac. These parameters cannot be monitored from the front panel.

Page 15 At this point, use the BrightEye Control Application to enable Freq Adjust and adjust the frequency to bring the BrightEye 55 into spec by making the rotation of its vector slow or stop. The specification of ±1Hz of subcarrier (in either PAL or NTSC) is met if the vector takes more than 1 second to make 1 full revolution.

Page 24: Return Loss
For digital circuits, a return loss of 15 dB is typical. This means that the energy returned is 15 dB less than the original signal. In analog circuits, a 40 dB figure is expected. BrightEye 55 - Page 24...
