Input connectors
The electrical configuration of each triaxial INPUT connector is shown in Figure 2-2. Connector
terminals are designated as follows:
• Inner (center) conductor of the connector (and triaxial cable): Input HI. This terminal
connects to one terminal of the device under test (DUT).
• Inner shield (ring) of the connector and inner cable shield: Input LO (analog common).
• Outer shield (ring) of connector (shell) and outer cable shield: Chassis ground.
Refer to Current measurement connections for additional information on using the input
connectors.
Analog output connectors
WARNING Analog output low can float up to ±30 V. Use care to avoid a shock hazard
when using the analog outputs.
Figure 2-2 shows the terminal configuration of each triaxial ANALOG OUT connector. Output
terminals are as follows:
• Inner (center) conductor: Analog output HI
• Inner shield: Analog output LO (floating analog common)
• Outer shield: Chassis ground
Refer to Analog output connections for additional information on using the analog output
connectors.
Voltage source output connectors
Each channel has a single OUTPUT banana jack for the voltage bias source. Each connector is
the HI terminal for the corresponding voltage source channel and connects to one terminal of the
device under test (DUT).
NOTE There are no separate external connections for voltage source LO. The LO node of each
voltage bias source is internally connected to the floating analog common. See
“Connection methods” later in this section for connection details.
Refer to Voltage source connections for additional information on using the voltage source output
connectors.
