Universal R-Box (N1265A-035)
This is a blank box, kind of a do-it-yourself kit for installing a resistor you want. Generally,
inserting a resister between SMU and DUT is effective for preventing SMU from
oscillation. You can insert your desired resistor by using this box. This box is designed for
using the MCSMU. See Figure 3-14 for connection example.
NOTE To install your desired resistor in the universal R-box, see "To Use Universal R-Box".
The Kelvin connection is effective up to the R-box input. So the voltage drop caused by the
series resistor must be subtracted from the measurement result as following.
Vdut = Vout - Rs  Imeas
where,
Vdut: Voltage after correction
Vout: Source output voltage
Rs: Resistance of the series resistor
Imeas: Measurement current
