19. Frequency Response, HP 8591EM

22.Set the EMC analyzer and the synthesizer/level generator to the next frequency settings listed in Table 2-25.

23.At each frequency, adjust the synthesizer/level generator amplitude for a MKR-1-TRK amplitude reading of 0.00 60.05 dB.

24.Record the synthesizer/level generator amplitude setting in column 2 of Table 2-25 as the synthesizer/level generator amplitude.

25.Repeat steps 22 through 24 for each frequency setting listed in Table 2-25.

26.For each of the frequencies in Table 2-25, subtract the Synthesizer/Level Generator Amplitude (column 2) from the Synthesizer/Level Generator Amplitude at 50 MHz recorded in step 19. Record the result as the Response Relative to 50 MHz (column 3) of Table 2-25.

27.Add to each of the Response Relative to 50 MHz entries in Table 2-25 the Error Relative to 300 MHz at 50 MHz recorded in step 11. Record the results as the Response Relative to 300 MHz (column 4) in Table 2-25.

Test Results

Perform the following steps to verify the frequency response of the EMC analyzer.

1.Enter the most positive number from Table 2-25, column 4: dB

2.Enter the most positive number from Table 2-24, column 2: dB

3.Record the more positive of numbers from steps 1 and 2 in TR Entry 1 of the performance veri￿cation test record.

4.Enter the most negative number from Table 2-25, column 4:

dB

5.Enter the most negative number from Table 2-24, column 2: dB

6.Record the more negative of numbers from steps 4 and 5 in TR Entry 2 of the performance veri￿cation test record.

7.Subtract the results of step 6 from the results of step 3. Record this value in TR Entry 3 of the performance veri￿cation test record.
