Installation Note

Description of the Upgrade

The following may apply to your "B" model PNA–X: 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 the two connected 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. This kit
replaces the Bias tee and the two 2.4 mm connected semi-rigid cables on
each port. The 2.4 mm couplers and connecting cables in your analyzer
must be replaced with new 3.5 mm couplers that are not included in this
kit.
IMPORTANT! It is possible your couplers were replaced with the new
3.5 mm parts during a previous repair. Please verify your coupler type
before ordering new 3.5 mm couplers. To order new couplers, refer to
"Contacting Keysight" on page
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. The items that are included in this kit,
replace the other 3.5 mm components (i.e., new bias combiners and
cables replace the other 3.5 mm components).
Be very careful to use the appropriate hardware in your analyzer. Using the
wrong hardware can ruin analyzer components, resulting in additional
customer costs.
This upgrade adds the low frequency extension (LFE) to an N5241/2/9B Option
423 4-port or Option 423 with 029 analyzer by adding:
— PC assembly, low frequency extension (LFE)
— bias combiners to all ports
— additional new cables
After installation of this upgrade, your analyzer will be an N5241/2/9B Option
425 or an Option 425 with 029.
