I found a use for the GPIB interface on my counter - record
the frequency drift of its internal timebase during warm up.
It looks like an oven warming up.  I don't know exactly which
timebase my 1992 has, but I did notice the 5 to 10 MHz doubler
on the back of the oscillator,  The back has separate coarse
and fine frequency adjustments.  Can someone identify which
timebase is fitted to this counter?

The link below has the story and plot.
