Figure 89: Using the output enable line
Front-panel control of output enable
To activate the output enable line:
1. Press the
CONFIG
key followed by the
OUTPUT ON/OFF
control.
2. Choose
DIO-CONTROL
, then press the
ENTER
key or the navigation wheel .
3. Select
OE_OUTPUT_OFF
to activate the output enable signal causing the source-measure unit
(SMU) output to be blocked if the output enable is not asserted (connected to +5 V). Select
NONE
to deactivate the output enable signal so that its state has no effect on the SMU output.
4. Press the
EXIT (LOCAL)
key as needed to return to the normal display.
Remote control of output enable
Use one of these commands* to control output enable action:
smu X .source.outputenableaction = smu X .OE_NONE
smu X .source.outputenableaction = smu X .OE_OUTPUT_OFF
*
smu X
: For the Model 2601B, this value is
smua
(SMU Channel A); for the Models 2602B and 2604B,
this value can be
smua
or
smub
(for SMU Channel A or SMU Channel B, respectively).
When set to
smu X .OE_NONE
, the Series 2600B does not take action when the output enable line is
low. When set to
smu X .OE_OUTPUT_OFF
, the instrument will turn its output off as if the
smu X .source.output = smu X .OUTPUT_OFF
command had been received. The instrument will
not automatically turn its output on when the output enable line returns to the high state. For example,
the following command activates the output enable for SMU A:
smua.source.outputenableaction = smua.OE_OUTPUT_OFF
