Example Overview
In this example, you use an HP 437B power meter to automatically
enter correction data into the array. It is necessary to turn off the
HP 8757 System Interface (controlled from the front-panel of the
analyzer) so that the swept CW generator can temporarily control
the power meter over HP-IB. When the correction data entry process
is complete, enable user flatness correction and set the desired
test port power level. Then store the correction table and swept
CW generator configuration in the same register that contains the
analyzer configuration. Re-activate the HP 8757 System Interface
and recall the stored register. Make sure that user flatness correction
is still enabled before making the measurement.
When an HP 437B 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 437B 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.
