Front Panel Description

LED lights when the module is accessed via the VXI backplane.

LED lights when the transmitter is enabled. LED blinks when data generated by this module is being transmitted. (”D” module only)

Sync extenders are used to extend the sync line from one mainframe

or module to another. It is an SMB connector for ECL levels and must be terminated in

50 ohms at each end of the chain.

BNC input for ECL or TTL signals that can trigger data acquisition. For ECL, the input is ac coupled, 1 k ohm, edge sensitive. For TTL, the input is

dc coupled, 1 k ohm, TTL levels.

LED lights when an optical signal is detected. LED blinks when data is being received.

(”D” module only)

Clock Extenders are used to connect the system reference from one mainframe or module to another. It is an SMB connector for ECL levels and must be terminated in 50 ohms at each end of the chain.

BNC input for TTL, ECL, or sine wave signals that can be used as the ADC sample clock. This input can also

be used for the system frequency reference. This input is ac coupled, and has 1 k ohm impedance.

This is the main input to the ADC. It is a single-ended input terminated into 50 ohms.
