Model 2602 Best Source Selector (BSS) is ideal for users requiring automatic evaluation and selection of a Best Source of telemetry data. The Model 2602 accepts bit synchronized inputs from multiple sources of mission telemetry, evaluates the real-time frame synchronization lock status of all sources every 5 milliseconds, then, automatically selects and routes the best sources out for processing. Operational status is both displayed for operator usage and logged for later analysis. At the heart of the Best Source Selector are the Frame Synchronization Verification Units (FSVU) and a high speed Matrix Switch. Each FSVU is capable of testing the status of eight individual sources of telemetry data simultaneously, while the Matrix Switch provides high speed signal switching and routing. During operation, a powerful processor evaluates the lock status of multiple sources according to user-defined parameters and directs the Matrix Switch to route the Best Source inputs to assigned output connectors. GUI Setup/Status display and control uses the built-in color LCD monitor & keyboard. You can view these same displays remotely on a Windows NT/2K/XP PC (with our optional Remote Display Software) over a built-in Ethernet port. Operational status info is also available in text form on our (optional) Remote Display Units, connected via RS422 serial ports. All data is logged to disk for post mission analysis/reporting.

The Model 2602 contains up to three FSVU’s. Each FSVU accepts 8 inputs and performs frame synchronization lock status testing using operator provided setup parameters. The high-speed Matrix Switch provides data and clock connectors for 24 input telemetry streams and 12 output best source telemetry streams. Operation of the Matrix Switch is controlled by a powerful processor which analyzes the various inputs according to the setup parameters and also provides display update and status logging. A complete format simulator for testing, as well as an IRIG time code translator, are also included. Adding FSVU’s in the field is easy and involves no additional I/O modifications. Every system ships with a full set of I/O support.

The RDU is a 3.5" RETMA rack-mounting chassis that displays the status of up to 12 best sources as determined by

the Model 2602 Best Source Selector at distances up to 500’. The RDU front panel provides 12 display areas, one for

each best source output. Each display consists of three LED’s and three alphanumeric displays. The LED’s indicate

that the best source is active/inactive, in Lock or Unlocked. The three alphanumeric displays will be illuminated if

The Model 2602 Telemetry Best Source Selector provides continuous, real-time testing of the frame synchronization lock status of multiple sources (single or multiple streams) of telemetry data. The BSS uses operator-entered parameters to determine which of up to four sources with identical formats is the best source, then switches that source to an assigned output connector for additional processing. You perform mission setup using an intuitive graphical user interface on the built-in color LCD display and the

retractable keyboard. During setup, using a point-and-click interface, you assign two to four individual sources of a given telemetry stream to a best source channel. Each source is also assigned a priority within its channel. You can either FORCE an input source to be always output as the best source within its channel, or allow AUTOMATIC best source selection to be performed by the BSS. After assigning multiple sources to a channel, you enter the bit rate, frame sync pattern, and minor frame length for the channel by keyboard or point-and-click. You can select an automatic setup test, which causes the simulator to route appropriately formatted test data signals to verify the switching strategy of the channel. The channel setups can be saved and recalled for re-use on future missions. At the start of data acquisition, in channels where the BSS AUTOMATIC mode is selected, the highest priority source

within the channel having frame synchronization lock is switched to the best source output connector for that channel. When you lose lock on a channel best source, the BSS immediately looks for a higher priority source within the channel to switch to. If none is found, the BSS then looks for a lower priority locked source in the channel to output. Should no other source within the channel be locked, no switching occurs. Channels in FORCE mode will not be switched regardless of changes in lock status. Input source and channel status are continuously updated and graphically displayed. Displayed information includes the channel assignment of each source, current sync lock status and cumulative (since start of mission) lock status percentage for each source, and current best source within each channel. The graphic display may also be accessed remotely via the standard Remote Display software, or in text form on up to six optional Remote Display Units or other devices. Status information is continuously logged to disk for post-mission analysis.
