15. Measure noise for 1 kHz offset:
a. CF = 1000.000950 Hz
b. Span = 1kHz
c. RBW =10 Hz
d. Avg count = 20 (note: If 20 averages does not result in a stable amplitude, more averages can be used.)
e. Marker frequency = 1000.001 MHz
f. After averaging is completed, enter the raw noise amplitude in dBm/Hz in the measurement table. (See Table 14
on page 33.)
g. Calculate a
nd record Phase noise, the difference of CW amplitude in 100 Hz filter and noise measured with the
power marker. (See Table 14.)
16. Record the results in the Test record.
