I am working on getting an HP 89441A up and running (I am trying to
measure the multi-path interference of received ATSC TV signals). Before
I can dive into it, I need to gather the appropriate cables to
interconnect the RF and IF sections. Most are straight forward (BNCs, a
db-9 serial cable, etc) but the adapter needed to connect the reference
output to reference input on the RF section is a bit, well, weird.
According to Keysight Find-A-Part it is HP part number 1250-1499.
Googling that part number brings up little in the way of sources, but
indicates that it was also used on the 8590 series of spectrum
analyzers. Taking a look at the back of my 8591, I could see that it
indeed has one which is pictured below. Now the question is where can I
get another one? Or, if I can't, will an ordinary BNC jumper work? Why
does it need to be this special 1-piece adapter?
There's nothing particularly special about it, just use a short piece
of decent coaxial cable.
