3.1.3 MCSMU connections
The MCSMU output connection example is shown in Figure 3-8.
For the connection of the MCSMU, the Keysight N1255A connection box is required.
Input panel provides six triaxial connectors for connecting two MCSMU and one GNDU
or SMU. Output panel provides six triaxial connectors for the High1, High2, and Low
terminals. See Figure 3-11 for image of the Input panel and the Output panel. Also see
Figure 3-8 for the connection image. And see Figure 3-10 for the internal connection. To
connect the N1255A Output terminals to the connectors as shown in Figure 3-9, use the
16494A triaxial cable.
Use the following cables to connect the N1255A to the MCSMU
•
16494A Triaxial cable, 2 ea. per one MCSMU
Use the following cables and adapter to connect the N1255A to the GNDU.
•
N1254A-100 GNDU to Kelvin adapter, 1ea.
•
16493K GNDU cable, 1ea.
•
16494A Triaxial cable, 1 ea.

N1255A Connection Example
NOTE
N1255A Input and Output terminals
If a MP/HP/HRSMU is connected instead of the GNDU, use the following cable. Also, do
not use the SMU current range less than 100 mA.
Voltage ranging of terminals is indicated near connector on the Input or Output panel.
The N1255A cannot be used for measurement of the IEC Measurement Category II, III, or
IV.
