Series 2600B
System SourceMeter® Instrument Reference Manual Section 2:
General operation
2600BS-901-01 Rev. C / August 2016 2-77
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*:
smuX.source.offmode = smuX.OUTPUT_NORMAL
To select the high-impedance output-off mode over a remote interface*:
smuX.source.offmode = smuX.OUTPUT_HIGH_Z
To select the zero output-off mode over a remote interface*:
smuX.source.offmode = smuX.OUTPUT_ZERO
* smuX: 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 (smuX.source.offmode = smuX.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
smuX.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
(smuX.source.offfunc = smuX.OUTPUT_DCVOLTS):
• The source-measure unit (SMU) sources 0 V.
• The current limit is set by the smuX.source.offlimiti attribute (default 1 mA).
When the output is turned off and the selected output-off function is CURRENT
(smuX.source.offfunc = smuX.OUTPUT_DCAMPS):
• The SMU sources 0 A.
• The voltage limit is set by the smuX.source.offlimitv attribute (default 40 V).
