21. Frequency Response , HP 8594EM
25. Set the EMC analyzer center frequency and the synthesizer/level generator
frequency to the frequencies listed in T able 2-34 . 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 2-34 as the Synthesizer/Level Generator Amplitude .
26. F or each of the frequencies in T able 2-34 , subtract the Synthesizer/Level
Generator Amplitude Reading (column 2) from the Synthesizer/Level
Generator Amplitude Setting (50 MHz) recorded in step 20. Record the
result as the Response Relative to 50 MHz (column 3) of T able 2-34 .
27. A dd to each of the Response Relative to 50 MHz entries in T able 2-34 the
Measuring Receiver Reading for 50 MHz listed in T able 2-33. Record the
results as the Response Relative to 300 MHz (column 4) in T able 2-34 .
28. Record the test results in the performance verication test record by
performing the following steps:
a. Enter the most positive number from T able 2-34 , column 4:
dB
b. Enter the most positive number from T able 2-33 , column 2:
dB
c. Enter the more positive of numbers from (a) and (b) as TR Entry 1 of
the performance verication test record. (Absolute referenced to 300
MHz.)
d. Enter the most negative number from T able 2-34 , column 4:
dB
e. Enter the most negative number from T able 2-33 , column 2:
dB
f. Enter the more negative of numbers from (d) and (e) as TR Entry 2 of
the performance verication test record.
g. Subtract (f) from (c), then enter this value as TR Entry 3 of the
performance verication test record. (Relative atness .)
