Dr. Jeff Sutherland,

You commented awhile back about a cable Alan Back made for you that let you adjust the impedence from a frequency generator (I believe you use an FScan) to match the input to the ABPA. You said this was designed to find the best match and then Alan would make a cable.

1) Have you determined the correct match yet?
2) How will you go about determining the best match without
   the possibilty of over-driving the ABPA?
3) Do you have any info on this cable you can share?
4) I am trying to hook up my ABPA to my GB4000 and have
   some specs for the GB4000. Do you have some for the
   FScan I could compare them to?
