Tim,

For 0.1 second gate time, my result is similar to yours. With my gate time 
set to 1 second, the "racking" drops to +/- 1E-10 (or less), for comparison.

HI all ,
I had a 5370 A shipped to me that suffered enough of a drop/roll to
break a handle and bend the chassis such that the bottom panel had to be
modified to get it back on.  When I connected the timebase output to the
start input the frequency display is 10.0000000xx with the last two
numbers moving about quite a lot.  Could this indicate damage to the
oscillator due to the drop?  I haven't tuned up the inputs yet so this
may be an artefact of that.
Thanks

Tim
