This firmware upgrade is compatible with all 8719D, 8720D and 8722D vector network analyzers which currently have firmware revision 7.12 or higher. Other versions of the 8719D, 8720D and 8722D require the purchase of Option 000, which is a CPU upgrade kit. Contact your local Keysight service center to schedule this CPU upgrade. This revision of firmware provides the 8719D, 8720D or 8722D with two auxiliary measurement channels in addition to the two primary measurement channels, thus all four S-parameter measurements may be displayed simultaneously.
