12. Measure noise for 1 MHz offset:
a. CF = 1000.95 MHz
b. Span = 1MHz
c. RBW = 1kHz
d. Avg count = 100
e. Marker frequency = 1000.997 MHz (note, this avoids the 1 MHz offset spur)
f. After averaging is completed, enter the raw noise amplit ude in dBm/Hz in the measurement table. (S ee Table 14.)
g. Calculate and record Phase noise, the difference of CW amplitude in 1 kHz filter and noise measured with the
POWER marke
r. (See Table 14.)
13. Measure noi
se for 100 kHz offset:
a. CF = 1000.0
95 MHz
b. Span = 100 k
Hz
c. RBW = 1kHz
d. Avg count
= 100
e. Marker fr
equency = 1000.100 MHz
f. After ave
raging is completed, enter the raw noise amplitude in dBm/Hz in the measurement table (See Table 14.)
and test record.
g. Calculate and record Phase noise, the difference of CW amplitude in 1 kHz filter and noise measured with the
POWER marker. (See Table 14.)
14. Measure noise for 10 kHz offset:
a. CF = 1000.0095 MHz
b. Span = 10 kHz
c. RBW = 100 Hz
d. Avg count =100
e. Marker frequency = 1000.010 MHz
f. After averaging is completed, enter the raw noise amplit ude in dBm/Hz in the measurement table. (S ee Table 14.)
g. Calculate and record Phase noise, the difference of CW amplitude in 100 Hz fi lter and noise measured with the
POWE
R marker.(See Table 14.)
