Measurement Techniques
Test Setup
Most tests are performed at the rear terminals of the supply as shown in Figure 2-1a. Measure the dc voltage directly
at the +S and -S terminals.

Note: Use dc supply with same polarity
connections for - CC tests.
Replace load with appropriate
resistor for CC noise test.
