1Connect the 33250A output to the channel 2 delay control input of the 81134A (use the BNC-SMA adaptor and a 20 dB attenuator).

2Connect a 20 dB attenuator each to the channel 1 and the trigger input of the DCA.

3Connect the 81134A channel 2 output to the DCA’s channel 1 input.

4Connect the 81134A trigger output to the DCA’s trigger input.

5Power on the three units after you have made all connections.
