Figure 2-33 3-Level Pulse Output Examples
The SPGU output channels can be setup to be a 3-level pulse generator by using the
SPM 3 command. A 3-level pulse source can be made by defining two 2-level pulse
sources. For example, the upper example in Figure 2-33 can be made by the
following command sequence.
