Coax Cable Selection for HP 37203A HPIB Extender
(1/1)
ZGoode:
Hi y'all,
I'm trying to figure out what kind of coax cable to use for my pair of 37203A.  The manual says to use coax with 75ohm impedance and a resistance of at most 4ohm/100m.  The obvious choice seems like it would be RG6, and I was planning on just taking a 100ft antenna extension cable, but from what I could find is that most RG6 likely does not meet the resistance specification.  What (cheaper) cable types should I be looking at here?
squadchannel:
The manual specifies Belden 9248 as the recommended cable; DCR is 6.4ohm/1000ft, so I assume it will work.
ZGoode:
Oh, nice.  I don't know how I missed that.  What page did you see that on?  The specs I was looking at were on page 3-2.

check sattelite cable such as CT100
the core conductor and air-space insulator are pretty much the same as RG6 but the outer shielding is much better.
