Hi Stan
With a 99 date code that's looking pretty old and will more than likely
have the earlier Piezo oscillator as per John's comments here

Hi Ian
That sounds encouraging, what's the date code on yours?
I seem to recall previous discussions here regarding the possibility of
firmware upgrades and am pretty sure the answer was "No".
My current Tbolts have firmware 3.xx but I have had some in the past with
version 2.xx and don't
Thanks Ian
Sounds like my original comments were somewhat over pessimistic then!
I was under the impression that the crossover between oscillators was
around 2002 but obviously it must have been quite a bit earlier.

Hi John
Not sure if this a response to my post or if the timing's just coincidence,
either way I still contend the Rigols offer a lot of bangs per buck but
that one still has to be very aware of the limitations.
Never any free lunches, but the snacks are sometimes quite good value:-)

I made a successful repair of a Racal 1991 counter that I originally
bought as a spares unit, the original switches and switch caps had already
been
removed and discarded, but decided after all that it was too good to just
use for parts, especially as all that ever seems to fail anyway are
Very nice, just what I would have hoped to achieve if I still had the
switch caps:-)

The other option of course is to pressurise the box with dry air to ensure

at all points, but it's probably easier just to provide a drain hole:-)

I really don't know who actually made it, what we generally used came from

It was an RS "own brand" product, indicated as suitable for protecting
