Performance Verification Tests
23. Frequency Response, Agilent E4402B and E4403B
For example, if Flatness Error is –0.30 dB and 50 MHz Ref Amptd is
0.15 dB, Flatness Relative to 50 MHz would be –0.45 dB.
31.If the analyzer has Option UKB, continue with this procedure.
Otherwise, perform the procedure in “Measuring Frequency
Response Less Than or Equal to 100 kHz.”
32.Replace the function generator with the synthesized sweeper.
33.Set the source frequency to 10 MHz and the source power level to the
value corresponding to the source power setting in Table 2-44 for the
current source frequency (10 MHz).
34.For an Agilent E4402B only, press Input/Output (or Input), Coupling
(AC) on the analyzer.
35.For an Agilent E4402B only, repeat step 5 through step 30 for ac
coupling.
36. Perform the procedure in “Measuring Frequency Response Less
Than or Equal to 100 kHz.”
