Figure 120: SweepVLogMeasureI()
Example
SweepVLogMeasureI(smua, 100,
1000, 0.02, 5)
This function performs a five-point logarithmic voltage
sweep starting at 100 V and stopping at 1000 V. Current
is measured at every step (point) in the sweep after a
20 ms source settling period.
The following table contains log values and corresponding
source levels for the five-point logarithmic sweep:

Usage
time
= timer.measure.t()
time
The elapsed time in seconds (1

s resolution)
Example 1
timer.reset()
-- (intervening code)
time = timer.measure.t()
print(time)
Resets the timer and measures the time since the
reset.
Output:
1.01
The output will vary. The above output indicates that
