The Keithley 2600-TRIAX Connector assembly (Figure 1) provides pathways from an SMU terminal block located on the Model 260x rear panel to three triax connectors. The triax connectors’ pathways are shown in Table 1 and Figure 2, as well as a low-noise chassis ground banana jack that can be used as a common signal ground point for Input/Output LOs (through cable Model CA-186-1). This low-noise signal ground banana jack is connected to the chassis through a Frequency Variable Resistor (FVR).
