Recommended Equipment
Power Supply
The Power Supply should be a low noise power supply.
Phase Noise / Spectrum Analyzer
For measuring phase noise an Agilent E5052A is recommended. An Agilent E4445A PSA Spectrum
Analyzer with the Phase Noise option is also usable although the architecture of the E5052A is superior
for phase noise measurements. At frequencies less than 100 MHz the local oscillator noise of the PSA
is too high and measurements will be of the local oscillator, not the device under test.
Oscilloscope
For measuring delay an Agilent Infiniium DSO81204A was used.
Reference Oscillator
The on board crystal oscillator will provide a low noise reference signal to the device at offsets greater
than 1 kHz.
Note: The default loop filter has a loop bandwidth of ~60 kHz. Inside the loop bandwidth of a PLL the
noise is greatly affected by any noise on the reference oscillator (OSCin). Therefore any noise on the
oscillator less than 60 kHz will be passed through and seen on the outputs. For this reason the main
output of a Signal Generator is not recommended for driving OSCin in this setup.
