User manual TEKTRONIX ECO422D SD-HD DATASHEET

[. . . ] Detection on individual channels may be disabled, giving the option of disabling changes to the backup unit on failure of signals not critical to the facility operation. When operated in the switch-on-fault mode, the ECO422D will automatically select the backup sync source should any of the primary inputs fail. However, in the unlikely event both sync sources are faulty, the ECO422D will not alternate between the two sources. [. . . ] 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. 12 dB at 360 MHz (15 dB typical) when selected. ELSW): 30 dB, 0 to 10 MHz. Insertion Loss ­ Power Source Mains Ranges ­ Voltage: 100 to 240 VAC, ±10%. Power consumption: 25 W maximum. Environmental Temperature ­ Operating: 0 °C to +40 °C, IEC1010-1 compliance. Nonoperating: -40 °C to +65 °C. Altitude ­ Channels 1-6: 0. 2 dB, DC to 10 MHz. In a frequency range of 10 MHz to 1. 5 GHz, the instrument approximates less than 20 meters of Belden 1694A cable.

ELSW): ±1 V (only for the tri-level sync and analog black-burst signals). Maximum Switched Current ­ 100 mA. Crosstalk (Unselected input to output or channel to channel) ­ Physical Characteristics Dimension mm in. Height Width Depth Weight 44 483 561 kg 1. 734 19. 0 22. 1 lb. Channels 1-6: -60 dB to 10 MHz. Relay Switch Time ­ Time that it takes for the relays to switch and settle. ELSW only) ­ Time that it takes for the channel to switch and settle. Amplitude Detection ­ The ECO422D will determine a fault condition exists when the input signal is less than 2 dB from the nominal level. The following are the amplitude ranges for the various types of input signals that will result in a fault condition.
