Please Note: One or more options are required when purchasing an ECO8000 Unit; please call for help with configuration or visit the "Accessories and Options" tab for purchasing and pricing details.

The following four options are mandatory to operate the ECO8000 Changeover Unit:

• ECO8000 DPW: Adds a second hot-swappable redundant (backup) power supply (a second power cord option is required)
• ECO8000 REF: Adds 3 x BNC channels (black burst, HD tri-level sync, AES/DARS, word clock)
• ECO8000 HREF: Adds 3 x high bandwidth BNC channels (3G-SDI, HD-SDI, SD-SDI, as well as black burst, HD tri-level sync, AES/DARS, word clock)
• ECO8000 LTC: Adds 4 x LTC channels

The Tektronix ECO8000 is a highly versatile automatic sync and signal changeover unit with configurations and capabilities required to address modern master sync application and other advanced sync timing application. The Tektronix ECO8000 offers exceptional reliability, stability and high availability and is designed with optional high bandwidth input changeover capabilities for HD/SD and/or 3G-SDI signal environments.

Each Tektronix ECO8000 unit can be used with the following signal generators to form the complete sync generator system, which offers extra redundancy for the critical timing and synchronization system in the facilities.

The Tektronix ECO8000 provides up to nine user-configurable BNC channels and four LTC channels. Each channel consists of primary and backup inputs, and an output. The base configuration of the Tektronix ECO8000 has three 50 MHz Electronic Fast Switch channels with options for six more 50 MHz Electronic Fast Switch or 3 GHz Relay Switch channels in groups of three channels each, plus four optional LTC channels.

The 50 MHz Electronic Fast Switch channels support black burst, HD tri-level sync, AES/DARS, and word clock signals. The 3 GHz Relay Switch of the Tektronix ECO8000 channels support SD/HD/3G-SDI signals as well as most analog reference signals. For applications that require more than nine BNC channels, two Tektronix ECO8000 can be configured to work as a single system which practically doubles the number of channels available (up to 18 BNC channels and eight LTC channels).

Channel Configuration

Channel configuration can be set either via the front panel or the Tektronix ECO8000 Web User Interface. Signal amplitude fault detection level follows the setting of the channel configuration. Detection on individual channel may be disabled, giving the option of disabling switching to the backup unit on failure of signals not critical to the facility operation.

Changeover Switching

When operated in the switch-on-fault mode, the Tektronix ECO8000 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 Tektronix ECO8000 will not alternate between the two sources. If necessary, this function may be overridden with the manual sync source selection. Manual source selection also facilitates periodic testing of the changeover function.

Front Panel Controls

In association with the LCD display, front-panel controls are provided for source selection, operating mode, resetting the fault indicators, and for disabling the front-panel controls. LED fault indicators are also provided for each individual channels as well as the status of the power supplies. When the unit is connected to an Ethernet network, these functions are also available from the Tektronix ECO8000 Web User Interface using a Web browser on a computer connected to the same network.

Optional Backup Power Supply

The optional hot-swappable, redundant (backup) dual power supply system (Option DPW) virtually removes the risk of sync loss due to power supply unit failure, minimizing disruption in operations. Unique to the Tektronix ECO8000, the Automatic Changeover Unit periodically tests the backup power supply to verify its performance. If the test fails, a fault will be indicated on the LED fault indicator as well as an error message for backup power supply replacement – providing extra assurance that the backup power supply will be ready when needed.

Each power supply module has both AC and DC indicator LEDs. These LEDs continue to operate for 10 minutes after the loss of power. This allows quick troubleshooting in the event of supply or AC power failure.

Alarm and Status Reporting

Alarm and status information can be reported through SNMP, GPI, email notification, and/or the Tektronix ECO8000 Web User Interface.
