User manual TEKTRONIX ECO422D SD-HD DATASHEET

[. . . ] Changeover Unit ECO422D SD/HD Data Sheet The ECO422D provides eleven user-configured channels, each channel consisting of primary and backup inputs, and an output. Six channels can be set for high-definition serial digital video, standard-definition serial digital video, AES/EBU digital audio, tri-level sync, and PAL or NTSC analog black burst Features & Benefits Switches Analog Black and Serial Digital Video, Both Standard and High-definition, and Digital Audio Eleven User-configurable Signal Channels Amplitude Detection on All Channels Electrical Fast Switch Function for Input Channels 4 to 6, with Option ELSW Automatic or Manual Operation Fault and Operating Mode Front-panel Indicators Five channels may be set for standard-definition serial digital video, AES/EBU digital audio, tri-level sync, and PAL or NTSC analog black burst Channel configuration is by internal DIP switch. Signal amplitude fault detection level follows the setting of the channel configuration switches. [. . . ] Front-panel controls are provided for source selection, operating mode, resetting the fault indicators, and for disabling the front-panel controls. Indication of fault and unit on line is also available through the remote connector. Applications Provides Complete Fault Tolerance when Used as a Switch Between Primary and Backup SPGs or TSGs The ECO422D is a highly versatile sync changeover unit designed for use in a serial SD/HD digital television environment. The ECO422D will accommodate component or composite serial digital video signals, AES/EBU digital audio, tri-level sync, and analog black-burst signals. This flexibility makes the ECO422D ideal for both the mixed-format and all-digital television facility. Data Sheet Characteristics Inputs and Outputs Return Loss ­ Channels 1-6: 30 dB, 0 to 10 MHz.
