You may substitute:
3.5Ω 1000W load resistor (6030A)
0.069Ω 1000W load resistor (6031A)
0.4Ω 1000W load resistor (6032A)
40Ω 1000W load resistor (6035A) in these tests:
CV Load Effect (Load Regulation) CV PARD (Ripple and Noise)
CCSource Effect (Line Regulation) CC PARD (Ripple and Noise)
The substitution of the load resistor requires adding a load switch and making minor changes to the procedures. The load transient recovery time test procedure is not amenable to modification for use with load resistors.
An electronic load is considerably easier to use than a load resistor. It eliminates the need for connecting resistors or rheostats in parallel to handle the power, it is much more stable than a
