In performing testing on Automatic Test Equipment (ATE) it is a challenge to accurately generate and measure RF (radio frequency) power. In an example embodiment, in a test apparatus ( 100 ) used for measuring the input and output characteristics of an amplifier ( 140 ), there is a method for determining test program parameters. The method ( 200 ) comprises calculating input loss from the test apparatus power source to the input of the amplifier ( 220 ), defining an input loss correction factor. The output loss from the amplifier output ( 220 ) to the power meter of the test apparatus is calculated, defining an output loss correction factor. Using the input loss correction factor ( 230 ), a real input power level is determined and using the output loss correction factor ( 230 ), a real output level is determined.
