Command Reference
SSR
Force2/Sense2 is connected to the SMU installed in the slot numbered slot-2.
where, slot is the slot number given by chnum.
NOTE To use SCUU
Before turn the Agilent B1500 on, connect the SCUU to the MFCMU and two
MPSMU/HRSMUs properly. The SCUU is used to switch the module (SMU or
MFCMU) connected to the DUT.
SSR
This command sets the connection mode of a SMU series resistor (approx. 1 MΩ)
for each channel.
If the output switch is opened, the SSR command just sets the mode, and the CN
command connects or disconnects the series resistor.
If the output switch is already closed, the SSR command connects the series resistor
to the SMU output. Then the output forces 0 V one moment.
A series resistor is mounted on each module. 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.
Execution
Conditions
The series resistor cannot be used for the measurements that use the HCSMU, the
HVSMU, the MCSMU, the SMU connected to the atto sense and switch unit (ASU),
or the measurements that use 1 A range of the HPSMU.
The channel must not be in the high voltage state (forcing more than the allowable
voltage for the interlock open condition, or voltage compliance set to more than it).
Syntax SSR chnum,mode
Parameters chnum : SMU channel number. Integer expression. 1 to 10 or 101 to 1001. See
Table 4-1 on page 4-16.
mode : Status of the series resistor. Integer expression.
0: Disconnect (initial setting).
1: Connect.
