TIS Function Reference
force_i
force_i
This function forces the specified current from the specified SMU.
Synopsis
int force_i(port, current, range, compliance)
int port;
double current, range, compliance;
Arguments
Item Range
Restriction/Description
port
Specify current output channel by using the port address or a pin
number that is assigned to the port by the connect_pin function.
Available
port
values are 1 to 49, SMU1 to SMU8, and values
shown in Table 2-2 on page 2-9.
current
Value of current to force. Numeric expression [A]. See Table 2-6
on page 2-12.
-
0.2 to 0.2 for MPSMU or
-
1.0 to 1.0 for HPSMU.
range
Current output range. Numeric expression [A]. See Table 2-6 on
page 2-12.
-
0.2 to 0.2 for MPSMU or
-
1.0 to 1.0 for HPSMU.
a
To use the auto ranging mode, set 0.
b
a. SMU uses limited auto ranging mode. The SMU forces current at the
specified range if the specified range can force the
current
. If not, the
SMU ranges up to range that can force the
current
.
b. SMU forces current at the lowest range that can force the
current
.
compliance
Voltage compliance value. Numeric expression [V]. See Table 2-6
on page 2-12. The
compliance
sets the maximum output voltage
of an SMU operating as a current source (I_SOURCE mode).
-
100 to 100 for MPSMU or
-
200 to 200 for HPSMU.
A macro REMAIN is also available. If you set REMAIN, the
compliance value is automatically set to the last compliance value
if the last output mode of this channel was I_SOURCE, or 20 V if
the last output mode was V_SOURCE.
