Upgrade Kit for N5241B/42B/49B Microwave Network Analyzers Installation Note Description of the Upgrade The following may apply to your "B" model PNA: In June 2013, the N5241A/AS and N5242A/AS analyzers underwent significant hardware changes. Some components that have 2.4 mm connectors (bias tees, couplers, and some semi-rigid cables) were replaced with components that have 3.5 mm connectors. If your analyzer’s serial number prefix is MY/SG/US5310 and below: Your analyzer was originally shipped with 2.4 mm components. Bias tees with 2.4 mm connectors are no longer available, so the bias tees and connecting cables included in this kit have 3.5 mm connectors. Since they are interconnected, the 2.4 mm couplers and connecting cables in your analyzer must be replaced with the new 3.5 mm items included in this kit. If your analyzer’s serial number prefix is MY/SG/US5321 and above: Your analyzer was shipped with 3.5 mm components, so it is not necessary to replace the couplers and connecting cables. These items are included in this kit, but will not be used for your upgrade. Set them aside for possible use in the future. Be very careful to use the appropriate hardware in your analyzer. Using the wrong hardware can ruin analyzer components, resulting in additional customer costs. If you had an A model PNA-X with Option 219/419 with Option H85 that was upgraded to a B model, please refer to Options 217/417. If you had an A model PNA-X with Option 224/423 with Option H85 that was upgraded to a B model then refer to Option 222/422.

4 Description of the Upgrade This upgrade converts your N5241B, N5242B, or N5249B Option 222 2-port analyzer to a N5241B, N5242B, or N5249B Option 422 4-port analyzer by adding: — an additional source bypass switch — an additional mixer brick — two additional bridges — four couplers — two additional source attenuators — two additional receiver attenuators — a splitter — a modified front panel, including 2 new test ports — many new cables
