Function Details

SMU Series Resistor

The series resistor (approx. 1 M) is mounted on each source/monitor unit module

(HRSMU, HPSMU, and MPSMU). The series resistor may be used for the device

protection, negative resistance measurement, and so on. It depends on the

characteristics of test device and measurement environment.

If you use a series resistor, the voltage you set is applied to the near side of the series

resistor. Thus, the voltage will be divided by the series resistor and the device under

test. The setting value is not the voltage at the device terminal.

To set the series resistor, refer to “Advanced Setup Window” on page 2-53.

The series resistor is not mounted on MCSMU, HCSMU, and HVSMU.

NOTE

Restrictions

The series resistor cannot be used for the measurements that use the SMU connected

to the Atto Sense and Switch Unit (ASU) or the measurements that use 1

A range of

the high power SMU (HPSMU).

The series resistor is set to OFF for the standby channels in the standby state.
