N1265A Connection Guide
Output Connection
Gate Terminals
Output terminals internally connected to the Gate input connectors on the rear panel. High
and Low terminals used for the gate drive.
Gate terminals are designed for using with the Selector Output terminals. See Figure 3-5 .
High should be connected to the gate or base terminal of a DUT. Low should be connected
to the source or emitter terminal of the DUT. See
Figure 3-4 for connection example.
CAUTION
Open the Gate terminals for the ultra high voltage measurement using UHVU.
Figure 3-4 Gate and Selector Output Connection Example
Selector Output Terminals
Selector is used to switch the measurement resource connected to the DUT. See Figure 3-5
and Table 3-7 for the connection path. Also see Figure 3-4 for connection example.
CAUTION
Open the terminals for the ultra high voltage measurement using UHVU.
1. Low Force and Low Sense output terminals
Force and Sense must be connected together at the low terminal of a DUT. Use the
banana-banana wire (N1254A-522) to connect the Low Force terminal for performing
the ultra high current measurement using UHCU.
2. High Force and High Sense output terminals
Force and Sense must be connected together at the high terminal of a DUT. Use the
banana-banana wire (N1254A-522) to connect the High Force terminal for performing
the ultra high current measurement using UHCU.
3. Guard terminal
Guard (high level) must be opened. You may extend it as close as possible to a DUT
terminal for reducing the leakage current of the extension cable.
4. Chassis common terminal
Use for grounding or shielding.
