SMU4000 Sweep Engine


SMU pulsed sweep diagram
The SMU4000 can source or sink different levels over time in a variety of "shapes" which can be run on demand, repeated or sequenced in order to generate multi-dimensional data sets:
  • STEADY - constant level over time
  • PULSE - vary level between two set points with variable time at each level
  • SWEEP - set start and end levels, number of steps and whether to sweep linearly or logarithmically
  • PULSED SWEEP - as sweep, but with a defined second level period between each step
  • LIST - user defined lists of up to 100000 points
For each mode there are a range of options for additional parameters. For example, sweep mode can sweep up and down in a dual sweep mode.

The measurement units that are swept depend on the operation mode, for example they are Watts in the LP (Load Power) operation mode.
