sourceLevel
sourceLevel
The source value; set to one of the following values:
Voltage: 0 V to ±20 V
Current: 0 A to ±3 A
X
Source-measure unit (SMU) channel (for example,
smua.source.levelv
applies
to SMU channel A)
Y
SMU source function (
v
= voltage,
i
= current)
Details
This attribute configures the output level of the voltage or current source.
If the source is configured as a voltage source and the output is on, the new
smu
X
.source.levelv
setting is sourced immediately. If the output is off or the source is configured as a current source, the
voltage level is sourced when the source is configured as a voltage source and the output is turned
on.
If the source is configured as a current source and the output is on, the new
smu
X
.source.leveli
setting is sourced immediately. If the output is off or the source is configured as a voltage source, the
current level is sourced when the source is configured as a current source and the output is turned
on.
The sign of
sourceLevel
dictates the polarity of the source. Positive values generate positive
voltage or current from the high terminal of the source relative to the low terminal. Negative values
generate negative voltage or current from the high terminal of the source relative to the low terminal.
The
reset()
function sets the source levels to 0 V and 0 A.
Example
smua.source.levelv = 1
Sets voltage source of SMU
channel A to 1 V.
