Measuring the Phase Noise
The analyzer gives an easy way to measure the phase noise. In the example below,
we use a generator (such as
RIGOL
DG3101A) to output a sine signal with 50 MHz
and -10 dBm as the signal under measure.
Procedures:
1.
Device attachment
Connect the output terminal of the generator to the RF INPUT 50Ω terminal on
the front panel of the analyzer.
2.
User the noise marker to measure
(1)
Reset the analyzer
-
Press Preset
(2)
Set the parameters
-
Press FREQ
-
Press Center Freq and enter 50 MHz.
-
Press SPAN
-
Press Span and enter 50 kHz.
-
Press BW
-
Press RBW and enter 1 kHz.
-
Press VBW and enter 100 Hz.
(3)
Measure the phase noise
-
Press Peak
Execute the peak searching and activate a marker.
-
Press Marker
-
Press Delta and enter 10 kHz.
Measure the amplitude attenuation that deviates 10 kHz from the signal.
-
Press Marker Fctn
-
Press Noise Mkr
3.
Measurement result
The measured amplitude attenuation of the signal whose frequency deviates 10
kHz is -79.85 dB/Hz, see figure below.
