2-Port Configuration, Option 200, S/N Prefix <6021
The following may apply to your B model PNA: In August 2020, the
N5224/44B and N5225/45B analyzers underwent multiple hardware
changes. Some instruments that have A25 – 5087-7765 HMA26.5
multiplier amplifier (with a discrete A26 power splitter and some
semi-rigid cables) and A27/A28 – 5087-7323/5087-6323 mixer bricks
(with 50 ohm pads and some semi-rigid cables) and were replaced with
integrated components: A25 – N5240-60101 (with a power splitter) and
A27/A28 – 5087-/5087-6417 (with the 50 ohm pads). Refer to the tables
in this section of the manual to learn which assemblies and cables may be
impacted by these changes.
The mixer block and 50 ohm pad changes do not impact PNAs with
Options 210/410. But, the HMA26.5 multiplier amplifier changes are
potentially applicable to all Options.
Be very careful to use the appropriate hardware in your analyzer. Using the
wrong hardware can ruin analyzer components, resulting in additional
customer costs.
