Acquisition loops to save data and restart automatically can be done
using a script like the LOOP.CTL supplied with the software. It contains
following lines:

onstop start
numruns=5
onlast run loopend.ctl
WAITINFO 2000 Test procedure, 5 runs in a loop
start
 
To use it, set any suited preset, for example a sweep preset of 20000 sweeps,
in the data operations dialog cross the checkboxes "Save at Halt" and "auto incr.",
then define one of the programmable toolbar icons as "run loop.ctl", and click that
toolbar icon.

This method is not well suited for very short runs like you mention with only 0.1s,
as stopping and restarting takes a rather long time of about 1 sec. To avoid that
deadtime, sequential mode is recommended:

In the settings dialog, set a sweep preset and cross the checkbox "Sequential cycles".
Define the "y-Range" as the number of wanted cycles, and start an acquisition.
The data is then sorted into a two-dimensional array, with the cycle number as
y-coordinate and time as x-coordinate.
