What changes what this is worth
Same catalogue number, different money. These are the attributes that separate two otherwise identical E4990A units — check each one before you quote or bid.
Option codes
Installed option codes. On configured units these are most of the value.
On the motor or drive nameplate, after the base part number.
Firmware revision
Firmware/FRN revision. Buyers match it to an existing project; a mismatch can make the unit useless to them.
On the label as "FRN" or "FW", and on the module's own display if it powers up.
Tested or untested
Tested / as-is / new-in-box. The single biggest multiplier on used price.
Not on the plate. It comes from whoever pulled the unit, and it moves the price more than anything printed.
