To Connect High Voltage R-Box
Keysight N1262A resistor box is used to reduce the risk of device breakdown or prevent
SMU from oscillation. The N1262A should be installed in your DUT interface as shown in
Table 5-1 on page 5-5.
N1262A-001: 1 M (± 3000 Vdc) resistor, HV(jack)-SHV(jack)
N1262A-002: 100 k (± 3000 Vdc) resistor, HV(jack)-SHV(jack)
N1262A-010: 1 k (± 200 Vdc) resistor, Triaxial(f)-Triaxial(f)
N1262A-011: 1 k (± 3000 Vdc) resistor, HV(jack)-SHV(jack)
N1262A-020: Universal R-box, Triaxial(f)-Triaxial(f)
N1262A-021: Universal R-box, HV(jack)-SHV(jack)
N1262A-023: Universal R-box, UHV(jack)-UHV(jack)
N1262A-036: 50 termination adapter
Universal R-box is kind of a do-it-yourself kit for installing a resistor you want. To install
the resistor, see "To Use Universal R-Box" on page 5-15.
N1262A-036 termination adapter is a BNC(f)-BNC(m) adapter which contains 50
resistor between signal line and shield. If a SMU is used as the gate drive for the
measurement using HVMCU, UHVU, or UHCU, the SMU may cause oscillation. Then
this adapter should be connected between the gate drive output and a DUT terminal. This
will be effective for preventing oscillation.
