40. Set the EMC analyzer center frequency and the synthesizer frequency to
the frequencies listed in T able 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 T able 2-41 as the
synthesizer/level generator Amplitude .
42. F or each of the frequencies in T able 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 T able 2-41 .
43. A dd to each of the Response Relative to 50 MHz entries in T able 2-41 the
measuring receiver Reading for 50 MHz listed in T able 2-38 . Record the
results as the Response Relative to 300 MHz (column 4) in T able 2-41 .
