In February 2012, the N5264A analyzer underwent significant hardware
changes. These changes included a redesigned Signal Processing ADC
Module (SPAM) board, Frequency Reference board, left side inner bracket,
and right side inner bracket. It is very important that this redesigned
hardware be used only with analyzer serial numbers prefixed
MY/SG/US5204 and above. If you have an analyzer whose serial number is
prefixed MY/SG/US5144 and below, you must use the previous version of
hardware rather than the redesigned hardware. Both versions of the
affected boards 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.
