Output
3. Allow the AC Measurement Standard to make several measurements and the reading
to settle. Convert the settled reading from V rms to dBm using the following formula:
The result must be within the tolerance listed in Table 5-11.
4. Set the UUT output to the next frequency listed in Table 5-11 for this test amplitude.
5. Repeat step 3 and confirm that the measured output level is within the tolerance
shown in Table 5-11.
