Digital Modulation Power Relative to CW Performance Test

This test applies to the following models:

M9381A

This test compares the digital modulation power level to the CW power level at the same frequency. A power meter and power sensor are used to measure the DUT output power in CW mode and in digital-modulation mode. The difference between the two power levels is compared to the specifications.
