4. Repeat the previous two steps to enter up to 12 frequency segments, depending on the required
accuracy.
You may enter multiple segments in any order because the analyzer automatically sorts them and lists
them on the display in increasing order of frequency.
If you only enter one frequency segment, the analyzer assumes that the single value is valid over the
entire frequency range of the correction.

Using Sample-and-Sweep Correction Mode

You can use the sample-and-sweep mode to correct the analyzer output power and update the power meter
correction data table, during the initial measurement sweep. Because the analyzer measures the actual
power at each frequency point during the initial sweep, the initial sweep time is significant. However, in this
mode of operation the analyzer does not require the power meter for subsequent sweeps. Therefore, this
mode sweeps considerably faster than the continuous correction mode.
