Performance Verification Tests
48. Tracking Generator Non-Harmonic Spurious Outputs: Agilent E4402B, E4403B, E4404B,
E4405B, E4407B, and E4408B (Option 1DN)
analyzer 50 Ω Input.
Measuring Fundamental Amplitudes
Perform the following two steps for each measurement value in Table
2-103.
6. Set the analyzer center frequency to the Fundamental Frequency
listed in Table 2-103 and press Single to activate a single sweep. Set
the microwave analyzer to the same frequency.
7. On the microwave analyzer, press PEAK SEARCH. Press MARKER →,
MKR → REF LVL. Wait for another sweep to finish. Press PEAK
SEARCH. Record the marker amplitude reading in Table 2-103 as the
fundamental amplitude.
Measuring Non-Harmonic Responses
8. On the analyzer, set the center frequency to the initial value
indicated in the first row of Table 2-103. Press Single on the analyzer
to trigger a single sweep.
9. Set the Start Freq, Stop Freq, and Res BW of the microwave
analyzer as indicated in the first row of Table 2-104.
10.Press SGL SWP on the microwave analyzer to activate a single sweep
and wait for the sweep to finish. Press PEAK SEARCH to locate the
largest spurious response.
11.Verify that the marked signal is not the fundamental or a harmonic
of the fundamental by performing the following steps:
NOTE The following steps are for an Agilent 8563E microwave analyzer, the
steps may be different if you are using another microwave analyzer.
a. Divide the marker frequency by the fundamental frequency (the
analyzer center frequency setting). For example, if the marker
frequency is 30.3 MHz and the fundamental frequency is 10 MHz,
dividing 30.3 MHz by 10 MHz yields 3.03.
b. Round the number calculated in step a to the nearest whole
number. In the example above, 3.03 should be rounded to 3.
Values less than 1 should be rounded up to 1.
