DOES ANYONE KNOW WHAT THE “SP” STANDS FOR ON THIS AGILENT/HP8920B-SP (TEST SET RADIO UNIT) SERIAL # U537253199
IT’S A NAVY UNIT, NSN 6625-01-498-2245..
Here is a list of the hardware options that were available for the 8920B. There may be a sticker on the back of the instrument which lists which of these options it has, if any.
This table is from the 8920B user guide on page 597.
Hi jlaguard,
I asked a bunch of people around the office, but the exact meaning of that SP designation is very elusive. The best lead we could find is this page from a national stock number search tool:
which seems to indicate that this instrument had to pass the Navy's own set of quality control standards. I don't have access to those QC specifications. Most likely, there will be no noticible difference between your SP instrument and a normal 8920B system in standard operating conditions.
I hope this helps.
