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.
