-SCS Parameter Analyzer Reference Manual Appendix E: Using a Keysight 8110A/8111A Pulse Generator

Switch matrix connections: When using a switch matrix that is equipped with triax connectors,
separate HI-to-LO matrix paths are required for the pulse generator. A typical connection scheme for
this type of switch matrix is shown below. As shown, OUTPUT 1(HI) is connected to a matrix row, and
the return path (LO) from the switch matrix is connected to the ground unit (GNDU). Note that in order
to complete the return path, a separate cable connection from the GNDU to the chassis of the pulse
generator is required. Remember, the chassis of the pulse generator is output LO.
Figure 617: Connections to switch matrix equipped with triaxial connectors
The following figure shows the actual pulse output signal path through the switch matrix to the device
under test (DUT), and back to the pulse generator. A more detailed look at signal paths is provided in
Using Switch Matrices (on page A-1
).

GPIB connections
The 4200A-SCS controls the pulse generator through the General Purpose Interface Bus (GPIB). Use
the 7007-1 or 7007-2 GPIB cable to connect the GPIB port of the pulse generator to the GPIB port of
the 4200A-SCS.
