The synthesizer module

5007 Typical Phase Noise

Phase noise was measured using the internal 10MHz reference with the Phase Detector Frequency set to

10MHz. The Frequency Increment was set to 1000kHz. The Charge Pump Current setting was 5mA.

The phase noise data was taken at the center of the 5 frequency bands. The phase noise will be slightly

higher at the top of each band and slightly lower at the bottom.

Using an external low phase noise frequency reference will also improve phase noise.
