In general, counter support in TimeLab is flaky with respect to any
instruments I don't actually own/use myself. Issues with the HP 5370B and
TimePod drivers are fixed ASAP because they affect me directly, and the same
is true of the TSC 5115A/5120A/5125A drivers. Everything else is provided
on a "best effort" basis, especially when talking about gear that I haven't
borrowed or otherwise worked with in person, and the Fluke/Philips counters
fall into the latter category. If all else fails the driver source code is
in the drivers/GPIB_TIC subdirectory under in the installation folder. :)
The talk-only driver is always your best bet when available. It will work
if the counter supports talk-only mode and is configured appropriately.
Some of the addressable drivers have been reported to skip every other
reading or fail to connect to the counter at all, especially with GPIB
adapters that use virtual COM ports or Ethernet dongles.
For both talk-only and addressable counters, pay close attention to how the
counter is set up at its front panel. TimeLab does not alter (m)any control
settings other than the bare minimum needed to fetch readings in whatever
mode the counter is currently in.
Finally, it's a good idea to use the latest beta from
www.miles.io/timelab/beta.htm rather than the 'release' build from
www.miles.io/timelab/readme.htm when working with counters. New features
and bug fixes that don't impact TimePod customers will not trigger immediate
updates of the release build.
