When replacing an old assembly, install an assembly with either the same
part number or the new part number.
In February 2012, the N5241A and N5242A analyzers underwent
significant hardware changes. These changes included a redesigned
Signal Processing ADC Module (SPAM) board, 13.5 GHz (source 1)
synthesizer board, 13.5 GHz (LO) synthesizer board, 13.5 GHz (source 2)
synthesizer board, frequency reference board, system motherboard, inner
cover (retaining shield), left side inner bracket, right side inner bracket,
chassis base, and test set deck. It is very important that this redesigned
hardware be used only with analyzer serial numbers prefixed
MY/SG/US5201 and above. If you have an analyzer whose serial number is
within this range, refer to the following table. If you have an analyzer
whose serial number is prefixed MY/SG/US5150 and below, you must use
the previous version of hardware rather than the redesigned hardware.
Both versions of the top assemblies hardware are included in the following
table.
Be very careful to use the appropriate hardware in your analyzer. Using the
wrong hardware can ruin analyzer components, resulting in additional
customer costs.
