Optimizing Performance
Creating and Applying User Flatness Correction
Chapter 360
Required Equipment
• Agilent E4416A/17A/18B/19B power meter
• Agilent 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
Figure 3-3 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 54.
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 your particular power meter/sensor, refer to its
operating guide.
Connect the Equipment
Connect the equipment as shown in Figure 3-3.
NOTE During the process of creating the user flatness correction array, the power
meter is slaved to the signal generator via GPIB. No other controllers are
allowed on the GPIB interface.
