Data
17.To record data for P
2
data in the 50 MHz to 40 GHz band, press .
18.Repeat steps 2 through 7 of this section of the procedure.
19.Enter the power value that is listed in the P
2
row of Table 2-10 for the particular
analyzer under test. After you enter the value, press .
20.Wait for the analyzer to complete one full sweep.
21.Press .
22.Read the marker value from the analyzer display and add 10 dB. Record the calculated
value in the 8722ET/ES (0.05 − 40 GHz) “P
2
Max.” column of the “Source Linearity”
performance test record.
23.Press .
24.Read the marker value from the analyzer display and add 10 dB. Record the calculated
value in the 8722ET/ES (0.05 − 40 GHz) “P
2
Min.” column of the “Source Linearity”
performance test record.

31.Read the marker value from the analyzer display and subtract 5 dB. Record the
calculated value in the 8722ET/ES (0.05 − 20 GHz) “P
3
Max.” column of the “Source
Linearity” performance test record.
32.Press .
33.Read the marker value from the analyzer display and subtract 5 dB. Record the
calculated value in the “P
3
Min.” column of the “Source Linearity” performance test
record.
If the Analyzer Fails This Test
• The source relies on the power linearity adjustment for correct performance. Refer to
Chapter 3 , “Adjustments and Correction Constants,” and perform the “Power Linearity
Adjustment” procedure. Then repeat this test.
• If the analyzer repeatedly fails this test, refer to Chapter 7 , “Source Troubleshooting.”
