E4416A/E4417A Power Meters Service Guide D-157
Therefore to attain a power of 100 mW as shown in the Table D- 2, instead of
applying 14.4493 Volts, the actual amount of voltage required from the
Universal Source would be:
14.4493 × 1.075533 = 15.6 Volts
By using the DMM Uncertainties calculated previously the worst case voltage
and corresponding power errors can be calculated.
