Using the Interface Board

The Interface Board (AXS83695) converts the differential Sweep Trigger, Digital K-Clock, and OCT Balanced Receiver outputs from SATA connectors into corresponding single-ended signals on SMA connectors for viewing on an oscilloscope. The Interface Board is also known as OCT Bulkhead PCB.

Making Connections

Below is a list of connections:

  • SATA cable 1 connects J1 on the Interface Board to J2 on the balanced receiver board (top board) for Channel 1 & Channel 2 OCT Balanced Receiver signals.

  • SATA cable 2 connects J2 on the Interface Board to J2 on the laser board (bottom board) for Sweep Trigger and Digital K-Clock signals.

  • P3 on DC power-Y cable connects to J4 or J5 on the Interface Board (either will work).

  • P1 or P2 on DC power-Y cable connects to J3 on the laser engine (either will work).

Mounting

The interface board can be mounted using the SMA connectors.

Make sure to place round Nylon spacers (¼ inch inner diameter) between the board and the mounting plate.

Use the gold plated lock and nut supplied on each SMA connector.
