depending on whether degrees or RAD has been selected for the phase unit.
"0..360°" The phase is displayed in the range 0° to 360°; only available if "°"
has been selected for the phase unit.
"-180..180°" The phase is displayed in the range +/- 180°; only available if "°" has
been selected for the phase unit.
"-360..0°" The phase is displayed in the range -360° to 0°; only available if "°"
has been selected for the phase unit.
"0..2π" The phase is displayed as a radian from 0 to 2π; only available if
"RAD" has been selected for the phase unit.
"-π..+π" The phase is displayed as a radian from -π to +π; only available if
"RAD" has been selected for the phase unit.
"-2π..0" The phase is displayed as a radian from –2π to 0; only available if
"RAD" has been selected for the phase unit.
"Infinite" The phase is displayed continuously (-∞ to +∞).
Note: The continuous phase display is mainly used for frequency
sweeps, to allow the phase characteristic to be displayed even in the
case of phase displacement above 360°. This measuring mode is
usually unsuitable for measurements without frequency variation
since such measurements do not have a valid previous value.
The continuous phase is measured by adding the phase difference
between two consecutive phase measurement results to the phase
measured value of the first measurement result:
     
1 2
where
mes mes 1 2
     
When configuring a frequency sweep for measuring the continuous
phase, the frequency step size and the number of sweep points must
be selected such that no phase shifts of more than 180° occur
between two consecutive sweep points.

5.35 Input Monitor
The input monitor is a pure level meter that acts as a level monitor and measures the
input level upstream of
all digital filters (thus also upstream of the prefilter).
