Check the listing for details. Anritsu/Wiltron Module/Board - A05 MOD DSP1, A06 MOD DSP2, 322U13220 - Network. Condition: For parts or not working. Listed at 249.00 USD. Anritsu/Wiltron module/board that I believe is for a vector network analyzer. This particular unit was owned by an Anritsu/Wiltron systems design engineer. There were no notes on this unit to indicate whether it was used in a machine or if it operates. It appears to be an older board... not sure of its age or its application.I am unable to test this part and I don't really know much about this technology. Therefore, it is sold as-is, as pictured.--This was owned by a former design/systems engineer for Anrtisu out of Morgan Hill, CA. He had many components, prototypes, and complete machines. If the component was bad, he typically marked it as such. I will not be listing items specifically marked as bad. I don't have the knowledge or capability to test, so all of the items are sold as-is. I have many misc supplies and equipment. If you want something specific, let me know.
