We have E5503B phase noise measurement system with 70422A down converter installed.

Can we swap 70422A with 70427A down converter to change our E5503B system to E5504B system that can measure up to 26.5GHz?

If not, what is difference between E5503B and E5504B system? Is there a upgrade path to upgrade our E5503B system to E5504B system?

Thank you in advance.
Best Regards,

Timothy

  Hello,
  
  Yes, the 70422A operates 1.6 to 18 GHz vs 70427A operates 1.6 to 26.5 GHz. They are interchangeable.
