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 4
.
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.
