When the output-off function is set to either voltage or current, the SMU may source or sink a very
small amount of power. In most cases, this source or sink power level is not significant.
Selecting the output-off function
This setting is used only when the when output is turned off and the source-measure unit (SMU) is in
NORMAL output-off mode.
To configure the output-off function from the front panel:
1. Press the
CONFIG
key.
2. Press the
OUTPUT ON/OFF
control.
3. Select
OFF-STATE
and then select
FUNCTION
.
4. Select
CURRENT
or
VOLTAGE
.
5. Press the
EXIT
key to return to the normal display.
To configure the output-off function remotely:
To set 0 V output with current limit set by the
smu
X
.source.offlimiti
attribute*:
smu
X
.source.offfunc = smu
X
.OUTPUT_DCVOLTS
To set 0 A output with voltage limit set by the
smu
X
.source.offlimitv
attribute*:
smu
X
.source.offfunc = smu
X
.OUTPUT_DCAMPS
*
smu
X
: For Models 2601B, 2611B, and 2635B, this value is
smua
(SMU Channel A); for Models
2602B, 2604B, 2612B, 2614B, 2634B, and 2636B, this value can be
smua
(for SMU Channel A) or
smub
(for SMU Channel B).
Output-off limits (compliance)
You can set output-off limits (compliance) for the current and voltage output-off functions using the
CONFIG menu on the Series 2600B front panel, or by setting the
smu
X
.source.offlimit
Y
attribute from a remote interface. The output-off limits only apply when the output-off mode is normal.
Setting the output-off limit for CURRENT (
smu
X
.source.offlimiti
) specifies the current limit for
the voltage source; setting the output-off limit for VOLTAGE (
smu
X
.source.offlimitv
) specifies
the voltage limit for the current source.
Setting output-off limits
To configure the output-off limits from the front panel of the Model:
1. Press the
CONFIG
key.
2. Press the
OUTPUT ON/OFF
control.
3. Select
OFF-STATE
and then select
LIMIT
.
4. Select
CURRENT
or
VOLTAGE
.
5. Set the limit value and then press the
ENTER
key or the navigation wheel
(for details, see
Setting values
(on page 2-21)).
6. Press the
EXIT
key to return to the normal display.
