Custom sweep
This sweep type lets you configure a customized sweep (via remote only). Programmable
sweep list parameters include the number of measurement points in the sweep, the current
source level at each point, pulse width, and pulse delay.
Figure 10
shows an example of a custom sweep. When this sweep is started, the output
goes to the first current level in the sweep after the delay period. The pulse period and time
between pulses is determined by the programmed pulse and delay parameters. The sweep
will continue through the points in the order they were programmed and stop after the last
current point.
The size of the current list determines the custom sweep size. Normally, the pulse width
list and delay list should be the same size as the current list. However, if the pulse width
and/or pulse delay list is shorter than the current list, the last pulse width and/or delay
point will be used for all subsequent current values.

Sweep count
For front panel operation, a sweep can automatically repeat a specified number of times
(finite sweep count) or it can repeat continuously (infinite sweep count).
For a finite count sweep, the readings are automatically stored in the buffer. The maximum
number of finite sweeps that can be performed is determined as follows:
Maximum finite sweep count = 1000 / # points in sweep.
For an infinite sweep count, the readings are not stored in the buffer.
Use the following menu sequence to set sweep count:
Press CONFIG > press SWEEP > select SWEEP COUNT > select FINITE or INFINITE.
If you select FINITE, you will be prompted to enter the sweep count.
