smuX.source.delay
X = SMU channel (a or b)
Attribute Source delay.
Usage smuX.source.delay = Y -- Writes source delay.
Set Y to one of the following values:
0 or smuX.DELAY_OFF No delay.
-1 or smuX.DELAY_AUTO Auto delay.
User_value Set user delay value.
Remarks
• This attribute allows for additional source settling time after an output step.
• The default is 0, no delays.
• Setting this attribute to DELAY_AUTO will cause a current range dependent delay to
be inserted when ever the source is changed.
• Y can be set to a specific user defined value that will set the delay that is used
regardless of range.
Example
Selects the delay to auto SMU A:
smua.source.delay = smua.DELAY_AUTO
smuX.source.func
X = SMU channel (a or b)
Attribute Source function.
Usage iv = smuX.source.func -- Reads source function.
smuX.source.func = iv -- Writes source function.
Set iv to one of the following values:
0 or smuX.OUTPUT_DCAMPS Selects current source function.
1 or smuX.OUTPUT_DCVOLTS Selects voltage source function.
Remarks
• Reading this attribute gives the output function of the source. Setting this attribute
configures the SMU as either a voltage source or a current source.
• The reset function selects the voltage function.
Details See Section 4 (basic operation).
Also see smuX.source.output, smuX.source.levelY
Example
Selects the source amps function for SMU A:
smua.source.func = smua.OUTPUT_DCAMPS
