Command Reference
Command Reference
SSR
This command sets the connection mode of a series resistor (approx. 1 M
Ω
) 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 high resolution
SMU (HRSMU) connected to the Atto Sense and Switch Unit (ASU) or the
measurements that use 1 A range of the high power SMU (HPSMU).
The channel must not be in the HIGH VOLTAGE state (forcing more than ±42 V, or
voltage compliance set to more than ±42 V).
Syntax
SSR chnum , mode
Parameters
chnum : Channel number. The value must be slot number where the module has
been installed. Integer expression. 1 to 8 (1 and 5 are not available for
HPSMU). See
Table 4-1 on page 4-9 .
mode : Status of the series resistor. Integer expression.
0: Disconnect (initial setting).
1: Connect.
