NOTICE: FlexDCA 86100D Support Frozen at A.07.61

FlexDCA A.07.80 and later do not support installation on 86100D mainframes. For continued access to the latest FlexDCA updates, consider trading in your 86100D for an N1000A (Trade-In Offer). 

Contact your local Keysight representative to discuss options, www.keysight.com/find/contactus.


Frequently Asked Questions:

Why freeze 86100D software support?

The 86100D has been discontinued since December 2019, maintaining software support becomes increasingly complex with time, and FlexDCA A.07.80 includes a significant .NET update. In order to continue to provide the best possible measurement experiences for all customers, Keysight has determined that FlexDCA A.07.80 is a prudent time to remove 86100D software support.

Are Keysight repair and calibration services still available for 86100D?

The 86100D is obsolete as of March 2025. Contact Keysight Support, support.keysight.com, to inquire about available repair and calibration services.

What will happen if I install FlexDCA A.07.80 on an 86100D?

The installation will fail. FlexDCA A.07.80 and later will not install on an 86100D.

Will previous versions of FlexDCA continue to work with my 86100D?

Yes. All versions released prior to A.07.80 support 86100D.

What is the last version of FlexDCA that my 86100D will support?

For Win7 or Win10, A.07.61 is the last version supported.

For WinXP, A.04.54 is the last version supported.

Note: There are no A.07.7x releases. FlexDCA version numbers jump from A.07.61 to A.07.80.

Is FlexDCA A.07.80 supported on my Windows 10 86100D?

No. Beginning with FlexDCA A.07.80, 86100Ds are not supported, regardless of operating system.

Can I still upgrade my 86100D to Windows 10?

No. As of December 2025, 86100D Windows 10 upgrade is no longer available.

What if I have support remaining on an 86100D license? Will Keysight re-host this license?

Requests for re-hosting are evaluated on a case-by-case basis. Contact Keysight Support, support.keysight.com.

Are plug-in modules and DCA-M instruments introduced with or after the A.07.80 release supported with my 86100D?

No. These DCA instruments require FlexDCA A.07.80 or later and therefore will not be recognized by an 86100D frame.

Will Flex-on-Flex connections from my PC to an 86100D continue to work?

No. With FlexDCA A.07.80 or later installed on a PC, Flex-on-Flex connections to 86100Ds are not supported. An earlier version of FlexDCA must be installed on the PC to use a Flex-on-Flex connection to an 86100D.

What if a software bug is discovered in a previous version of FlexDCA?

Any defect fixes deemed critical by Keysight will be implemented in a special A.07.6x release. Non-critical defects in earlier software releases will not be addressed.
