  • Page 65: Transmission Line Considerations

    Circuit Board Design Transmission Line Considerations Stubs connecting signal transmission lines to the connector should be as short as feasible. Longer stubs will cause more loading and reflections on a transmission line. If the electrical length of a stub is less than 1/5 of the signal rise time, it can be modeled as a lumped capacitance.

  • Page 66: Recommended Routing

    Circuit Board Design Recommended Routing Two rows of compliant contacts in the probe make contact with pads laid down on the surface of the PC board. These contacts provide an extremely low probe load (<0.70 pF per channel), and make a good electrical connection with a small amount of compression force on a choice of standard PCB platings.

  • Page 69 Circuit Board Design - To realize 17 data inputs (in full-channel mode) while using time tags in addition to a clock input on a single 16760A module or on the master module in a multi-card set, you must route the data signals to pod 2 and the clock to pod 1. A convenient way to avoid laying out a second connector to connect only the clock signal is to use the Keysight E5382A flying-lead set to make the connection to the clock.
