Accessories
1. Module Selector Output (N1259A-300)
See Figure 3-2 and Table 3-2 for the status indicator and the connection path.
a. Low Force and Sense output terminals
Force and Sense must be connected together at the low terminal of a DUT.
b. High Force, Sense, and Guard output terminals
Force and Sense must be connected together at the high terminal of a DUT.
And Guard must be opened. You may extend it as close as possible to the
DUT terminal for reducing the leakage current of the extension cable.
NOTE Module selector may emit a noise sound during operation. However it is not
abnormal status.
2. Resistor box
For reducing damage of DUT or preventing SMU from oscillation. The
following resistors are available by the options.
