† The upper and lower limits in Results table 5-25, Results table 5-26, Results table 5-27, and Results
table 5-28 are calculated on the assumption that it was possible to set the exact level on the external
Modulation meter. If it is not possible to achieve this, the limits will need to be calculated for the
DVM readings obtained.
