When the I-Source is the selected source:
•
The programmed I-Source value remains on the display.
•
Internally, the V-Source is selected and set to 0 V.
•
Current compliance is set to the programmed Source I value or to 10 percent full-scale of the
present current range, whichever is greater.
•
Measurements are performed and displayed.
The Series 2600B can be used as an I-Meter when it is in zero output-off mode because it will output
0 V, but measure current.
To configure the output-off mode from the front panel:
1. Press the
CONFIG
key.
2. Press the
OUTPUT ON/OFF
control.
3. Select
OFF-STATE
.
4. Select
MODE
.
5. Select the output-off mode:
HI-Z
(high-impedance),
NORMAL
, or
ZERO
.
6. Press the
EXIT
key to return to the normal display.
To select the normal output-off mode over a remote interface*:
smu
X
.source.offmode = smu
X
.OUTPUT_NORMAL
To select the high-impedance output-off mode over a remote interface*:
smu
X
.source.offmode = smu
X
.OUTPUT_HIGH_Z
To select the zero output-off mode over a remote interface*:
smu
X
.source.offmode = smu
X
.OUTPUT_ZERO
*
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 function
This setting is used only when the when output is turned off and the Series 2600B is in NORMAL
output-off mode (
smu
X
.source.offmode = smu
X
.OUTPUT_NORMAL
).
When the Series 2600B is in NORMAL output-off mode, you can set the output-off function to
CURRENT or VOLTAGE through the CONFIG menu on the front panel, or by using the
smu
X
.source.offfunc
attribute from a remote interface. VOLTAGE is the default output-off
function.
When the output is turned off and the selected output-off function is VOLTAGE
(
smu
X
.source.offfunc = smu
X
.OUTPUT_DCVOLTS
):
•
The source-measure unit (SMU) sources 0 V.
•
The current limit is set by the
smu
X
.source.offlimiti
attribute (default 1 mA).
When the output is turned off and the selected output-off function is CURRENT
(
smu
X
.source.offfunc = smu
X
.OUTPUT_DCAMPS
):
•
The SMU sources 0 A.
•
The voltage limit is set by the
smu
X
.source.offlimitv
attribute (default 40 V).
