The invention discloses a multi-channel power measurement and display method and apparatus. The method comprises the following steps: s1. creating a carrier channel parameter table; s2. setting the number of offset channel pairs to be tested, and establishing an offset channel parameter table; s3. establishing a unified scanning parameter table and an offset channel scanning parameter table; s4. obtaining unified scanning data and offset channel independent scanning data by performing scanning measurement on carrier channels and offset channels; s5. calculating channel data of the carrier channels and each offset channel by use of the unified scanning data and the offset channel independent scanning data; s6. calculating absolute power values of the carrier channels and absolute and relative power values of the offset channels according to the channel data; s7. assembling trajectory data for display; and s8. creating an integrated display report of multi-channel power measurement. According to the invention, an effective solution is provided for users in solving the verification analysis problem of specific channel power characteristics.
