Hi Lamont<br>
<br>
According to the HP 3586 user manual the B variant already has a BNC input that is switchable between 50 and 75 Ohms.<br>
<br>
The A and B variants were teleco "specials" the C variant was the general use one, however it is quite possible that your B may not be as the manual and was customised for a specific client.<br>
<br>
A by far larger problem with 3586's is the NiCad ram backup battery which leaks and contaminates/corrodes the PCB edge connector, this must be the first check that you do.<br>

I waiting to get it, I 'm pretty excited, but also concerned it will need repair.<br>
In the listing I note is the display has error code of CE-1. The manual says,<br>
"Operator error, Attempt made to Manualy change the FULL SCALE while in Auto Range"<br>
So I hope that is not a real problem.<br>
I will be changing the WECO input connectors to BNC. I note the unit is 75 ohm, I'll be working with<br>
50 ohms.Is it wise to put a 50 ohm to 75 ohm L pad internal when I install the BNC connector?<br>
And then note, "all measurements are MINUS5.72 DB".<br>
What would I add/subtract if I just plugged a 50 source into the 75 ohm input?<br>
Thanks, Lamont<br>
