Oscilloscope control question?

[Salmon Egg]

I recently obtained a used oscilloscope that seems to be in good shape. It
is a Kikusui COS6100M. I never heard of it either, but it looks like a
Tektronix rip-off. There are two controls whose functions I do not
understand.

There are two pairs of coaxial knobs associated with the A and B sweeps
respectively. The small center knobs are for setting the triggering level
for the A and B sweeps. I understand them. The outer ring knobs give me the
trouble. The one associated with the A sweep is marked "HOLDOFF." The one
associated with the B sweep is marked "TRACE SEP."

Just what are the functions for these knobs?

I have found answers for myself.

Holdoff sets the holdoff time for the A (main) timebase. Which means
the trigger condition is ignored for a certain amount of time

Trace separation sets the horizontal separation of the trace produced
by the A timebase sweep and the B timebase sweep. So you can see both
sweeps same time on your scopes display.

Try to get a manual of the kikusui scope, function is explained there
too in detail.
