Optimizing Performance
Creating and Applying User Flatness Correction
Creating a User Flatness Correction Array
In this example, you create a user flatness correction array. The flatness
correction array contains ten frequency correction pairs (amplitude correction
values for specified frequencies), from 1 to 10 GHz in 1 GHz intervals.
An Keysight E4416A/17A/18B/19B power meter (controlled by the signal
generator via GPIB) and E4413A power sensor are used to measure the RF
output amplitude at the specified correction frequencies and transfer the
results to the signal generator. The signal generator reads the power level data
from the power meter, calculates the correction values, and stores the
correction pairs in a user flatness correction array.
If you do not have the required Keysight power meter, or if your power meter
does not have a GPIB interface, you can enter correction values manually.
Required Equipment
— Keysight E4416A/17A or Keysight N1913A/14A power meter
— Keysight E4413A E Series CW power sensor
— GPIB interface cable
— adapters and cables, as required
NOTE
If the setup has an external leveling configuration, the equipment setup in
assumes that the steps necessary to correctly level the RF output
have been followed. If you have questions about external leveling, refer to
“Using External Leveling” on page 147
Configure the Power Meter
1.
Select SCPI as the remote language for the power meter.
2.
Zero and calibrate the power sensor to the power meter.
3.
Enter the appropriate power sensor calibration factors into the power
meter as appropriate.
4.
Enable the power meter’s cal factor array.
NOTE
For operating information on a particular power meter/sensor, refer to its
operating guide.
