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.
