Creating a User Flatness Array Automatically, Example 1
In this example, a flatness array containing correction frequencies
from 4 to 10 GHz at 1 GHz intervals is created. An HP
438B
power
meter controlled by the synthesizer through the interface bus is used
to enter the correction data into the flatness array.
For this example, refer to menu map 5, POWER.
1. The equipment setup shown in Figure 1-18 assumes that if the
setup has an external leveling configuration, the steps necessary
to correctly level have been followed. If you have questions about
external leveling refer to earlier paragraphs titled, “Externally
Leveling the Synthesizer.”

2. Zero and calibrate the power meter/sensor.
3. Enter the appropriate power sensor calibration factors into the
power meter.
4. Enable the power meter/sensor cal factor array. For operating
information on the HP
437B
power refer to its operating and
service manual.
5. Connect the power sensor to the point where corrected power is
desired.
