3. Enter 10 MHz into the Calibrator Mainframe. Allow the power meter reading to
stabilize, then enter the power meter’s reading in Column B of Table 6-62.
4. Enter the next frequency listed in Table 6-62. Allow the power meter’s reading to
stabilize, then enter the reading into Column A of the table.
5. Enter 10 MHz into the Calibrator Mainframe. Allow the power meter reading to
stabilize, then enter the power meter’s reading in Column B of Table 6-62.
6. Repeat steps 4 and 5 for all of frequencies listed in Table 6-62. Continue until you
have completed Columns A and B.
7. When you have completed Columns A and B, press Y to remove the Calibrator
Mainframe’s output. Complete Table 6-62 by performing the calculations for each
column. Compare Column E to the specifications listed in the final column.

Complete Columns A-E as follows:
A Enter the E4418A present frequency Reading (W).
B Enter the E4418A 10 MHz Reading (W).
C Apply power sensor correction factor for present frequency (W): CF * (Column A entry).
D Apply power sensor correction factor for 10 MHz (W): CF * (Column B entry).
E Compute and enter Error relative to 10 MHz (%): 100 * (sqrt(Column C entry) -
sqrt(Column D entry)) / sqrt(Column D entry).
