the stored register. Make sure that user flatness correction is still
enabled before making the measurement.
When an HP power meter is used to automatically enter the
correction data, the correction calibration routine automatically turns
off any active modulation, then re-activates the modulation upon
the completion of the data entry process. Therefore, the scalar pulse
modulation that is automatically enabled in a scalar measurement
system is disabled during an HP
correction calibration.
Note The user flatness correction array cannot be stored to a disk. You
must make sure that the array is stored in one of the eight internal
registers. Recalling a file from an HP 8757 disk will not erase the
current array; therefore you may recall an array from an internal
register, then recall an associated file from a disk.
For this example, refer to menu map 5, POWER.

you have followed the steps necessary to correctly level the
configuration. If you have questions about external leveling
