vstart • : 0V
vstop • : 10V
vsteps • : 100
After setup, the output is zeroed and enabled. A linear voltage
sweep from the start to the stop value is performed. At each step,
the collector-emitter current (I

) is measured.
Upon sweep completion, the output is disabled and the data is
written to the Instrument Console window of TSB.
3.6.5 Modifying Program 8
For different sweep values, simply modify the vstart , vstop ,
and vstep values and source range parameter as appropriate.
In order to speed up the test procedure, you may wish to use
a faster integration period. Simply change the l _ nplc value.
Note, however, that changing this parameter may result in unac-
ceptable reading noise.
