phase-continuous switching

the pts x10 sets new standards by offering users a 2 mhz bandwidth of ultra-low phase noise ａnd low spurious phase-continuous switching range. furthermore, the 2 mhz bandwidth can be switch-se-lected to span either even or odd mhz steps, guaranteeing phase-continuous coverage in the neighborhood of any se-lected output frequency.

example: consider the pts x10 configured to cover the 40-50 mhz decade.

with switch-se-lected even coverage, phase-continuous spans are: 40-41.999999, 42-43.999999, 44-45.999999, 46-47.999999, 48-49.999999

with switch-se-lected odd coverage, phase-continuous spans are: 39-40.999999, 41-42.999999,43-44.999999, 45-46.999999, 47-48.999999
