2-7 Spectrum Analyzer Absolute Amplitude Accuracy Verification
The tests in the following two sections verify the absolute amplitude accuracy of the Spectrum Analyzer in the
MS272xC Spectrum Master. The two parts of this test are “50 MHz Amplitude Accuracy Verification”
immediately below and “Amplitude Accuracy Across Frequency Verification” on page 2-16.
