PTS x10 FREQUENCY SYNTHESIZER

  • 10 MHz bandwidth, configured to cover any specified decade from 0.1 - 100 MHz
    (0.1-10, 10-20, …, 80-90, 90-100)
  • 1 Hz resolution with DDS phase-continuous switching
  • fully programmable, BCD or GPIB, with remote-only versions available

The PTS x10 transfers the accuracy and stability of a frequency standard (built-in or external) to any output frequency within the configured 10 MHz decade specified by the user at the time of order (e.g., 20-30 MHz, 30-40 MHz, etc.). Additional optional field-installable replacement modules allow easy and rapid reconfiguration to another selected decade.

 

NOTE:  PTS x10 shown for illustration in "M" and "R" cabinets. Consult catalog for full cabinet style listing and cabinet mechanical specifications.

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-selected to span either even or odd MHz steps, guaranteeing phase-continuous coverage in the neighborhood of any selected output frequency.

Example: Consider the PTS x10 configured to cover the 40-50 MHz decade.

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

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