If the source is configured as a current source and the output is on, the new smuX.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
Sets voltage source of SMU channel A to 1 V.

Limit voltage:
2601B, 2602B, 2604B: 40 (40 V)
2611B, 2612B, 2614B, 2634B, 2635B, 2636B:
20 (20 V)
Limit current:
2601B, 2602B, 2604B: 1 (1 A)
2611B, 2612B, 2614B, 2634B, 2635B, 2636B:
100e-3 (100 mA)
Limit power: 0 (disabled)
Usage
limit = smuX.source.limitY
smuX.source.limitY = limit
The compliance limit value; set to one of the following values:
Voltage compliance:
2601B, 2602B, 2604B: 10 mV to 40 V
2611B, 2612B, 2614B, 2634B, 2635B, 2636B: 20 mV to 200 V
Current compliance:
2601B, 2602B, 2604B, 2611B, 2612B, 2614B: 10 nA to 3 A
2634B, 2635B, 2636B: 100 pA to 1.5 A
