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?
