d. Repeat the measurement for synthesizer output levels of 0, –5, and –10 dBm.
9. Perform the calculations and operation check as follows:
a. Subtract the Reference Power Measurement of row 5 from the Reference Power Measurement of
row 6. Record this value in the Correction column of rows 1 through 5.
b. Add the Reference Power Measurement and Correction values of row 1 and record the result in the
Corrected Reference Power Measurement column of row 1.
c. Repeat step 9b for rows 2 through 10.
d. Subtract the MA24106A Measurement of row 1 from the Corrected Reference Power Measurement
of row 1 and record the result in the Difference Calculation column of row 1.
e. Repeat step 9d for rows 2 through 10.
f. Find the largest (most positive) value in the Difference Calculation column and record this value
next to the word Max in row 11.
g. Find the smallest (least positive or most negative) value in the Difference Calculation column and
record this value next to the word Min in row 12.
h. Subtract the Min value from step 9g from the Max value from step 9f and record the result next to
the word Delta in row 13.
i. The Delta result should be less than 0.3 dB. If it is larger, contact Anritsu customer service.
10. Repeat the entire measurement and calculations with synthesizer frequency settings of 2 GHz, 4 GHz,
and 6 GHz.

Note: The Correction column of rows 1 through 5 should all have the same value.
The Correction column of rows 6 through 10 have values of 0.
