Source memory sweep
For a source memory sweep, up to 100 setup configurations can be saved in memory.
When the sweep is run, the setup at each memory point is recalled. This allows multiple
functions and math expressions to be used in a sweep.
A SourceMeter setup configuration is saved in memory by performing the following menu
sequence:
Press MENU > select SAVESETUP > select SOURCE MEMORY > select SAVE
After selecting SAVE, you will be prompted to enter the memory location where you want
to store the setup.
After saving all your test setups in concurrent memory locations, use the following menu
sequence to configure the sweep:
Press CONFIG > press SWEEP > select TYPE > select SRC MEMORY
After selecting SRC MEMORY, the following menu items will be displayed:
START — Use this menu item to set the starting memory location for the sweep. For
example, if your first setup is stored in memory location 001, set the start point to 001.
# POINTS — Use to specify the number of points (memory locations) in the sweep. For
example, if there are 10 points in the sweep, set the number of points to 010.
NOTE NPLC caching can be used to speed up source memory sweeps. See “NPLC cach-
ing” in Section 3 of the Model 6430 Instruction Manual.
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 = 2500 / # 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.
