HP11848A and HP3561A |
PN3048
Phase Noise Measurement Software
is a Windows program for measuring the phase noise of many
different types of signal
sources and two port devices using the HP11848A Phase Noise
Interface and HP3561A Spectrum Analyzer. With these basic
instruments, phase noise may be measured at offsets from the
carrier of .01Hz to 100Khz. With the addition of an HP RF
spectrum analyzer, such as the HP3585A/B, offsets out to 40Mhz
may be measured.
The program has been under development for several years and
at present supports several different types of phase noise
measurement scenarios:
- Phase noise using a phase locked loop
- Phase noise without phase locked loop
- Phase noise using an FM discriminator

Here is a screenshot of the program
with several phase noise measurements from various different low noise
oscillators.
