Keysight PNA "A"-to-"B" Model Upgrade


Keysight Technologies is proud to introduce the N524xB PNA-X, N522xB PNA, and N523xB PNA-L products. These products contain all of the functionality that existed in the "A" model. These "B" models have the fresh, new Keysight appearance and an updated user interface. In addition, the application software licensing has been changed, and the PNA-X hardware option structure has been simplified.

The new option and software structure is detailed in the configuration guide.

An overview of all of the changes is contained in this B Model Overview PDF document.

Standard hardware upgrades ordered in conjunction with the A to B model upgrade (N52xxAU-690) are ordered under the A model hardware upgrade option N52xxAUxxx.

Information on the DDS (Direct Digital Synthesizers) Enhancement can be found in this PNA Enhancement PDF document. The enhanced DDS synthesizer is not included in the A to B model (N52xxAU-690) upgrade.

DDS upgrades are ordered under the B model upgrade option (N52xxBU-xS7). For more upgrade information please refer to the “Updates and Upgrades” tab on this page. Note: N5244B/45B models require s/n 5200xxxx and above.

All N524xA PNA-X, N522xA PNA, and N523xA PNA-L products built after 01 Dec 2015 (serial numbers MY/US5540 and above) can be upgraded to their respective "B" models by simply ordering the N52xxAU-690 upgrade kit. This kit contains a new front panel with labels, outer cover, front handles, side straps, and a new Windows 10 solid-state drive (N5242-60135) and Microsoft Certificate of Authenticity label. All software options in the PNA prior to being upgraded will be converted over to the B-Model "S93xxxB" application license format.

At the conclusion of this upgrade, every part is identical to a new "B" model. The upgraded unit can be fully supported the entire time Keysight sells new "B" models, plus five years after that.

Older PNAs will require the purchase and installation of additional hardware along with the A-to-B upgrade kit.

To determine any additional requirements for each individual PNA, you can run this Upgrade Evaluation Program which will look at each component and determine the parts that are required* in addition to the option 690 upgrade kit. This program can be run on the PNA itself or it can be run on a PC. If run on a PC, you must then enter the IP address or Computer Name of each PNA to be tested. The PC must have had the PNAProxy program installed on it. Alternately, you can run the program on a PNA and then specify any other PNA by IP Address. Each PNA must have firmware A.09.10 or greater. Make sure the PNA application is already running when you launch the program. See sample screen shot.

Option H29: For three years, Agilent/Keysight sold the N5244A and N5245A with option H29, Noise Figure measurements up to 26.5 GHz. In 2012, option H29 was discontinued and replaced with option 029. Support for option H29 was not continued into the firmware for the N52xxB models. Instruments with option H29 cannot be upgraded from the A to B model.

The installation of the A-to-B upgrade kit requires that the PNA has the following hardware:

AssemblyPart NumberSerial prefix for PNAs that started using these boards
(PNAs with these serial prefixes do not need to be upgraded.)
Can be ordered using the part number, or:
CPU, version 7W1312-60211MY/US5540 and aboveN8989A-PC7
SPAM 5N5240-60078
For 2-port PNAs, also order 1x N5247-60023 and 1x N5247-60024
MY/US5200 and aboveN8989A-SP5
IF Multiplexer, version BN5240-60062MY/US5240 and aboveN8989A-MX2
Synthesizers, versions E, F or G*
(See note below)
N5240-60076 (single board) or N5242-60168 (3 board kit)
Note: 2-port PNAs without option 224 need two synthesizer boards.
4-port PNAs or 2-port option 224 PNAs need three synthsizer boards.
MY/US5120 and aboveN8989A-SR6

N5245-60163MY/US4940 and above-----

*Note: N8989A-SR6 synthesizers are not needed when A to B model upgrade is ordered along with the DDS synthesizer upgrade (N524xBU-2S7/N524xBU-4S7/N522xBU-2S7/N522xBU-4S7).

If the CPU, SPAM, IF Multiplexer, or Synthesizer boards do not match the part numbers shown here, they will need to be ordered along with the option 690 upgrade kit. Some N8989A options include a small fee to cover the cost of adjusting the boards. The xxxxx-xxxxx part numbers can be ordered through Keysight's Find-A-Part page. Ordering parts this way is more expensive than ordering the N8989A options, but no additional fee will be charged for installation or adjustments when installing these boards along with the model upgrade.

The A-to-B upgrade is ordered as N52xxAU-690. Since each upgrade kit contains material unique to each model number, the upgrade model ordered must match the unit being upgraded.

All upgrades must be performed at a Keysight service center. The new licensing system requires that the instrument be registered and initialized on the Keysight domain. If the requirement to send the instrument to Keysight for upgrading is problematic, please contact us for possible alternatives.

The cost of the upgrade kit, installation, and a full calibration is approximately $13k. The cost of the other hardware required for older PNA-X configurations can be as high as $20k. The service centers can issue a separate quote for this additional hardware, if it is not ordered up front.
