a) Automatic mode (Default setting)
This setting is recommended for standard situations and ensures
reliable results.
After a defined interval, the level range is automatically and slowly
increased, if the current level values lie permanently above the
level range. In the same way the level range is reduced, if the
current level values lie permanently below the level range.
b) Manual mode
This setting is recommended, if you want to work with maximum
interference suppression and if you desire greatest possible in-
fluencing control for measurements.
If the interruption is too long due to excess noise, it is possible
to manually increase the level range with Continue, so that the
sensitivity level is reduced. The measurement is continued with
the operator ignoring a certain level of interfering noise.
If the current level values fall below the level range, an adjust-
ment is automatically performed, i.e., the correlator is set to a
more sensitive level.
c) Off
It is recommended to select this setting only in situations which are
marked by frequently returning, strongly varying signals resulting
in the measurement being frequently interrupted, thus preventing
a correlation completely.
Noise suppression is disabled. With this setting, it is accepted
that interfering noise is jamming the leakage noise from time to
time.
