Single Sweep 10 MHz to 110 GHz Measurement Solution
Keysight Technologies, Inc. currently offers the N5251A single sweep 10 MHz to
110 GHz vector network analyzer solution.

The N5251A solution uses a millimeter-wave test controller and a combination
of broadband frequency extenders that provide a male 1.0 mm test port output
connector. Users can purchase the N5251A as a single product solution or
configure using separate components. This allows for existing N5227A PNA
users the capability to add the N5261A or N5262A test controller and broadband
frequency extenders to make measurements from 10 MHz to 110 GHz.

For users that have or wish to purchase the N5247A 67 GHz PNA-X, you can
also extend these to cover a single sweep 10 MHz to 110 GHz measurement by
adding the N5261A / 62A test set controller and a set of broadband frequency
extenders.

The Keysight 110 GHz solution is the only broadband solution with integrated
tri-axial bias tees that provide accurate control of device bias through its force/
sense ability. This solution is ideal for device characterization, modeling and
parameter extraction in coaxial or on-wafer. The broad frequency coverage down
to 10 MHz offers superb time domain resolution. With the introduction of the
N5251A, accurate leveled power can be applied to the device being measured
providing the ability to sweep the power at the 1.0 mm port.

N5251A Single Sweep Solution (10 MHz to 110 GHz)
This configuration of the millimeter network analyzer is based on the N5227A
PNA network analyzer. It allows both a single sweep measurement solution
that starts at 10 MHz and goes to 110 GHz. This solution is intended as a
replacement for the HP 8510XF solution and has improved performance
capability. In particular it adds the capability to control and use receiver leveling
to set the power accurately at the 1.0 mm test port. Architecturally very similar
to the existing N5250C but allows for the configuration of either a 2 or 4 port
10 MHz to110 GHz measurements. Refer to the configuration information at the
end of this section.
