5. Calculate the YTO frequency error by subtracting the frequency
recorded in step 3 from the frequency recorded in step 4. Record the
result below:
YTO Frequency Error = YTO Frequency
(MEASURED)
−YTO
Frequency
(CALCULATED)
6. On the HP 8560E/EC, press MORE 1 OF 2, FREQ DIAGNOSE, and
FRAC N FREQ. Record the fractional N frequency below:
YTO Frequency Error = ________________________MHz
Fractional N frequency = _____________________________MHz
