Corby,
Power Basic certainly does the job. However, there's a fairly big learning
curve. I use Just Basic, which is a FREE cut-down version of Liberty Basic.
While there are a few limitations, and some things you need to do aren't
entirely intuitive, it works very well and the serial comms

Hi!
I forgot to mention, but the peak group delay of a pole pair is d_peak =
2*Q/w0 = Q / (pi * f0)
Hence, the group delay increases linearly with increasing Q values.
Shift the Q, and your delay vary, shift the center-frequency, and you
dip off the peak.
Cheers,

At least some of the HP splitters have RF filters in them. The same is true of
GPS receivers. A receiver or splitter in the attic will have many of the same

Hi Corby,
Do consider John's TimeLab program: Windows, free, easy to use, wonderful live
plots, phase, frequency, ADEV, etc. You will be amazed. Download from

It supports the SR620 directly as well as a number of other popular counters.

If they had done USB instead of HPIB / GPIB, a lot of the drivers would have
been out of service by the time Windows 95 came along. No chance at all of
them working under Windows 7.
For the complexity, it'd have been better if they used something more like
Ethernet. Except in 1968, you would

Again, I'd say it's the lowest common denominator. Synchronous comm using
RS-232 levels on a DB-25 came before asynchronous comm. It's long dead.
Being first isn't *always* best. Same could be said of 125V / 60 ma current
loops. I suspect serial will easily outlive RS-232 levels though.

Commodore computers in the longago dimdark past serialized the GPIB.
They started out with the GPIB as the disk drive and printer interface
from the get-go. I used a Commodore as a cheap controller when Hp GPIB
controllers cost a small fortune.

As you add pole-pairs, their group delay contributions adds up. However,

The SR620 I worked on was unused for a long time, and would not turn on. Seems
the power switch was oxidized and would not self-clean. Had to unmount it so I
could use chemical cleaners without getting any residue on the case or PCB.

is easy to galvanically isolate if necessary, is easy to debug, uses
the fewest pins, and is well supported on both ends although if
needed, USB to serial translation always seems to cause more problems
than it solves.
