3. Press {Configure Step Array}. This opens a menu for entering the user flatness
step array data.
4. Press {Freq Start} > [1] > {GHz}.
5. Press {Freq Stop} > [10] > {GHz}.
6. Press {# of Points} > [10] > [Enter]. Steps 4, 5, and 6 enter the desired flatness-
corrected frequencies into the step array.

step array.
8. Press [Amplitude] > [0] > {dBm}.
9. Press [RF On/Off]. This activates the RF output and the RF ON

NOTE If using an Agilent E4417A/18A/19A power meter,
follow these steps to configure the signal generator
to perform the user flatness correction:
10. Press [Amplitude] > {More (1 of 2)} > This allows you to choose another power

{Power Meter and E4417A, E4418A, or E4419A}.
11. Press [Meter Address] > [enter the power This configures the signal generator to interface

12. Press [Meter Channel A B] to select the
power meter’s active channel.
13. Press [Meter Timeout] to adjust the length of
time before the instrument generates a timeout
error while unsuccessfully attempting to
communicate with the power meter.
1. Press {More (1 of 2)} > {User Flatness} > This performs the user flatness correction. The
{Do Cal}. signal generator enters the user flatness correction
routine and a progress bar is shown on the display.
2. When prompted, press {Done}. This loads the amplitude correction values into the
user flatness correction array.
If desired, press {Configure Cal Array}. This opens the user flatness correction array,
where you can view the stored amplitude
correction values. The user flatness correction
array title displays User Flatness: (UNSTORED)
indicating that the current user flatness correction
array data has not been saved to the
memory catalog.

NOTE If you are not using an
Agilent E4416A/17A/18A/19A power
meter, or if you do not have GPIB
interface capability, you can perform
the user flatness correction manually.
