Optimizing Performance

Creating and Applying User Flatness Correction

2. Configure the signal generator to interface with the power meter.

a.Press Amplitude > More (1 of 2) > User Flatness > More (1 of 2) > Power Meter > E4416A, E4417A, E4418B, or E4419B.

b. Press Meter Address > enter the power meter’s GPIB address > Enter.

c.For E4417A and E4419B models, press Meter Channel A B to select the power meter’s active channel.

d. Press Meter Timeout to adjust the length of time before the instrument generates a timeout error if unsuccessfully attempting to communicate with the power meter.

3.Press More (2 of 2) > Configure Cal Array > More (1 of 2) > Preset List > Confirm Preset.

This opens the User Flatness table editor and resets the cal array frequency/correction list.

4.Press Configure Step Array.

This opens a menu for entering the user flatness step array data.

5.Press Freq Start > 26.5 > GHz.

6.Press Freq Stop > 40 > GHz.

7.Press # of Points > 28 > Enter.

This enters the desired flatness- corrected frequencies (26.5 GHz to 40 GHz in 500 MHz intervals) into the step array.

8.Press Return > Load Cal Array From Step Array > Confirm Load From Step Data.

This populates the user flatness correction array with the frequency settings defined in the step array.

9.Press Amplitude > 0 > dBm.

10.Press RF On/Off.

This activates the RF output and the RF ON annunciator is displayed on the signal generator.

Perform the User Flatness Correction

NOTE If you are not using an Agilent E4416A/17A/18B/19B power meter, or if your power meter does not have a GPIB interface, you can perform the user flatness correction manually. For instructions, see Performing the User Flatness Correction Manually below.

1.Press More (1 of 2) > User Flatness > Do Cal.

This creates the user flatness amplitude correction value table entries. The signal generator begins 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 list of defined frequencies and their calculated amplitude correction values. The user flatness correction array title displays
