and 1DQ
7. Enter the appropriate power sensor Cal Factor for the test frequency
into the power meter as indicated on the label of the power sensor.
8. Record the power level displayed on the power meter as the Level
Flatness in Table 3-8.
9. Repeat steps 7 through 8 to measure the flatness at each center
frequency setting listed in Table 3-8. The ⇑ may be used to tune to
center frequencies above 500 MHz.
NOTE 75 Ω RF Out only: Repeat steps 5 through 7 to measure the flatness at
the frequencies above 1 MHz listed in Table 3-8.
