Keysight PNA Millimeter Wave Support Home Page

The Keysight millimeter wave systems consists of a PNA, an interconnect test set, and a number of high frequency "heads". Broadband systems have been sold under the different model numbers shown here. Banded millimeter systems are also supported using most PNA models.


N5290A and N5291A Systems

The N5290A and N5291A systems have improved 1.0 mm coax test ports and have full 900 Hz to 110 GHz (N5290A) or 900 Hz to 120 GHz (N5291A) sweep capability. The system consists of:

  • PNA/PNA-X: N5222B-205, N5227B-205, N5242B-425, or N5247B-425
  • Test Set: N5292A
  • Heads: N5293A (110 GHz) or N5295A (120 GHz)

The N5290A and N5291A, as defined here, come with full warranted specifications which can be verified with TME performance verification software.


The firmware for this system also supports other PNA-based configurations which are not specified. These broadband or banded configurations are not referred to as N5290A or N5291A systems.

Broadband PNA-based Configurations:

  • PNA/PNA-X: any N5222B, N5224B, N5225B, or N5227B without 205; any N5242B, N5244B, N5245B, or N5247B without 425
  • Test Set: N5292A
  • Heads: N5293A (110 GHz) or N5295A (120 GHz)

All of these connected together into one system will function as a full 10 MHz to 120 GHz millimeter system. But these are NOT an N5290A or N5291A. These systems DO NOT have full millimeter specifications. These systems will be treated like the N5251A.

Banded PNA-based Configurations:

  • PNA/PNA-X: any N5222B, N5224B, N5225B, or N5227B; any N5242B, N5244B, N5245B, or N5247B
  • Test Set: N5292A, N5261A, N5262A
  • Heads: OML or VDI banded heads. See the OML/VDI model table for a complete listing of available heads.

All of these connected together into one system will function as a banded millimeter system. These systems DO NOT have any specifications.

N5251A System

The N5251A system has 1.0 mm coax test ports and has 10 MHz to 110 GHz full sweep capability. The system consists of:

  • N5227A PNA with option 201 or 219 or 401 or 419
  • N5261A or N5262A Test Set
  • Set of Two or Four Heads:
    • N5250AL20 left head(s) with attenuator and bias tee; One or two N5250AR20 right head(s) without attenuator, with bias tee
    • One or two N5250AL20 left head(s) with attenuator and bias tee; One or two N5250AR30 right head(s) with attenuator and bias tee

Problem with 2-port N5261A test set

If there is a problem using an N5261A 2-port test set with PNA firmware A.09.80.20, the problem is most likely caused by the firmware. Upgrade the firmware to A.09.90.08 or later and the problem should be fixed.

Operational Verification for mmWave Systems

Operational verification procedures are supported for various mmWave systems. These procedures are typically performed at initial system installation and whenever confirmation of proper system performance is required.

Operational verification procedures for N5250A/C and N5251A mmWave systems do not use fixed pass/fail limits. Various performance characteristics are measured. The user then compares these measurements to measurements made previously on the system or to values from known standards (such as those in a verification kit). Pass/fail determination requires engineering judgment.

Annual system calibration is only supported on N5290A and N5291A mmWave systems. These are the only systems which have "hard" specifications. For the other systems, there is no requirement for an annual calibration. Instead, an annual calibration may be performed stand-alone on the network analyzer that is part of the system.

Of course, a "user" calibration is supported for all mmWave systems. This is a calibration performed with a calibration kit prior to making measurements with a system.

The sections below provide links to detailed operational verification information for various types of mmWave systems.

N5251A 110GHz Swept Systems

See Chapter 6 of N5251A Installation and Service Guide (N5251-90001).

Systems based on OML heads

See the System Operation Verification section of N5261A/62A User's and Service Guide (N5262-90001). These instructions assume the OML head is used with an N5261A/62A controller. If a controller is not used (i.e. direct connect), then modify the instructions accordingly.

Systems based on VDI heads

See Operational Verification for VDI Heads.
