Model 4210-MMPC-C
Multi-Measurement Prober Cable Kit
Quick Start Guide
Setup using the Keithley Model 4225-RPM for I-V, C-V, or pulse I-V
measurements
NOTE
The setup for three-pin pulse I-V testing requires three prober cable kits. The setups
for four-pin testing require four prober cable kits.
The 4225-RPM is a Remote Amplifier/Switch that is an optional item to the Model 4225-PMU. The PMU has two
channels, so each PMU instrument card supports two (2) RPMs. The MMPC cables simplify the connection and re-
connection between the instruments and the device-under-test. The combination of the MMPC cables with the
RPM permits testing I-V, C-V, or pulse I-V automatically, without any manual cable re-connections. When using
only two RPMs on a four-terminal device, some re-cabling is required for certain C-V test configurations.
The 4225-RPM has the appropriate connector types at the input and output of the RPM enclosure to eliminate any
adapters when connecting cables to the RPM. On the input side, there are two triax connectors for SMU Force and
SMU Sense. There are two SMA connectors for CVU POT and CVU CUR. There is also an RPM control connector
for the control and power of the RPM from the 4225-PMU. The output of the RPM is a pair of triax cables (Force
and Sense), which connect directly to the MMPC cables as shown in the figures below.
See Section 16 of the 4200 Reference Manual for 4225-PMU and 4225-RPM information and how to configure an
ITM for a pulse IV test.
2 Channel I-V or Pulse I-V Setup
For most I-V and pulse I-V testing, only two source/measure channels are typically used. The two active signals are
connected to the gate and drain, and the source (and bulk, if present) is connected to ground (see Figures 17 and
18). For the C-V test setup shown in Figure 19, all four source/measure channels are used.
