ECO8000 Automatic Changeover Unit Datasheet

Lire en ligne :

The 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. This changeover unit 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.

Features & Benefits
  • Switches analog black burst, HD tri-level sync, AES/DARS, word clock, LTC, as well as SD/HD/3G-SDI signals - all the timing and synchronization signals required in modern broadcast, production, and post production facilities
  • Scalable product architecture to fit various application needs
  • Electronic Fast Switch function for near glitch-less sync source switching, minimizing disruption in operations
  • Automatic or Manual changeover mode
  • Front panel LED fault indicators for each individual channel as well as the status of the power supplies
  • Dual hot-swappable power supplies ensure continuous availability of reference signals
  • Easy to manage with Web-based interface for configuration and SNMP for status and alert information
Applications
  • Sync generator and time reference generator system for broadcast, studio, mobile, and post-production facilities
  • Master or slave (genlock) operation for distributed system architectures

This changeover 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.

  • A pair of Tektronix Master Sync / Master Clock Reference Generators (SPG8000) for most broadcast facility timing applications
  • A pair of Tektronix Test Signal Generators (TG8000) for more advanced post production facility timing applications

Instrument configuration

The 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 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 channels support SD/HD/3G-SDI signals as well as most analog reference signals.

For applications that require more than nine BNC channels, two ECO8000 instruments 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 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 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 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.

50 MHz Electronic Fast Switch channels

The Electronic Fast Switch function, which comes standard with all 50 MHz Electronic Fast Switch channels, significantly improves the changeover switching speed and thus minimizes disturbance of the reference sync signals when switching between primary and backup inputs. The Electronic Fast Switch channels have latching relay backups that engage on loss of power to maintain the selected signal path.

Optional 3 GHz Relay Switch channels

The optional 3 GHz Relay Switch channels are optimized for SD/HD/3G-SDI signals, but are also usable for most reference signals. These channels utilize high bandwidth latching relays to preserve the selected signal path upon a loss of power.

In addition, these channels are equipped with the Tektronix patent-pending "Relay Check" function 1. When this function is enabled, the instrument automatically checks the signal level on each 3 GHz Relay Switch channel before and after every changeover switch to determine the condition of the relay contacts of these channels. If it is determined that the relay contacts may have nonconductive coating (such as oxide) buildup, the instrument will cycle the relay rapidly for 20 times to wear through the layer of nonconductive coating in an attempt to restore the relay connections (relay self-cleaning attempt).

1 The Relay Check function on the 3 GHz Relay Switch channels operates only on channels that are connected (terminated).

Optional LTC channels

The optional LTC channel connections are pin-compatible with the Tektronix SPG8000 and TG8000 1 generators, so these signals can be connected with standard 15 pin D-SUB cables. The same cable can be used to carry GPI connections, which allow the SPG8000 to trigger a changeover on certain error conditions such as loss of genlock.

1 The TG8000 generator must have a GPS7 module installed in order to support LTC generation.

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 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 ECO8000 and ECO8020, the 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 ECO8000 Web User Interface.
