Hewlett Packard E4407B ESA-E Series Spectrum Analyzer 26.5GHz Works, Error-Parts

Manufacturer: Hewlett Packard HP

Model: E4407B

Condition: For Parts or Not Working. Comes in non-original packaging.  This unit is in fair cosmetic condition, with minor blemishes from prior use.  There are scuffs/scratches/stains and adhesive label residues here and there all over, and the covers look yellow.  The feet have stubborn stains all around.  There are some small dings on the cover over the display area, and the display has some dust inside.  The battery label indicates the internal battery is 25 years old.
The photos show the exact item(s) the buyer will receive.

Notes: This analyzer is in PARTIAL working condition.  The display is dim, and has a yellow cast to all colors, but is still usable in normal room lighting.  At every power-on, even if it was still plugged into the main and with Auto-align set to ON, it will give a message, "System, Alignments, Align Now, All Required."  It will additionally always set errors, "Printer interface error, Option not installed", "Undefined header", and "Data out of range".   Alignments are able to complete with no errors called out.  Aside from all that, it seems to work.  We were able to display signals from 9kHz to 12.5GHz, and from +10 to -80 dBm (limits of our generator and cabling).  The amplitude reference measures almost exactly 50 MHz and -20 dBm.  We are not able to test any of the rear-panel interfaces.  No other testing was done.
No manuals, cords/cables, or additional items are included if not listed or shown.
