Once the probe has been switched on and
detected, you can switch between sym-
metric and asymmetric operation using
Symmetry.

In asymmetric operation, the useful signal
is hidden so that you see only noise and
any interference sources (see example
illustration).
Time domain (9):

or

In the line scope, you can switch from the
frequency range to the time domain. In
this respect, the line scope operates like
an oscilloscope that permits display of AC
voltages from 0 to 40 V
pp
with a resolution
of 2 mV
pp
.

This makes it easy to recognize different
AC voltage signals, e.g. the square-wave
signal of an E1 access.
If ARGUS detects that the connected

signal regularly exceeds a certain thresh-
old, ARGUS tries to trigger automatically
in response to this so as to optimally

display the signal in the time domain.
The trigger symbol is green.

If no signal is present or the level is too
low, the trigger symbol is red. ARGUS
does not trigger.

The gain and time base can be set using the horizontal and vertical cursor
keys analogous to the frequency range.
The cursor functions are also available in the time domain for analysing the
signal. However, there is no zoom function.
