23. Frequency Response, HP 8596EM

38.Replace the 50 MHz to 12.8 GHz power sensor with the 50 ￿ termination.

39.On the EMC analyzer, press the following key:

4MKR !5 MARKER ! HIGH More 1 of 3 More 2 of 3 MARKER 1 4MKR5 More 1 of 3 MK TRACK ON OFF (ON)

40.Set the EMC analyzer center frequency and the synthesizer frequency to the frequencies listed in Table 2-41.

41.At each frequency, adjust the synthesizer/level generator amplitude for a MKR 1-TRK amplitude reading of 0.00 60.05 dB. Record the synthesizer/level generator Amplitude Setting in Table 2-41 as the synthesizer/level generator Amplitude.

42.For each of the frequencies in Table 2-41, subtract the synthesizer/level generator Amplitude Reading (column 2) from the synthesizer/level generator Amplitude Setting (50 MHz) recorded in step 37. Record the result as the Response Relative to 50 MHz (column 3) of Table 2-41.

43.Add to each of the Response Relative to 50 MHz entries in Table 2-41 the measuring receiver Reading for 50 MHz listed in Table 2-38. Record the results as the Response Relative to 300 MHz (column 4) in Table 2-41.
