the Connection Control menu (see section Table-Oriented
Version on p. 4.73 ff.)
Attenuation Setting for the attenuation of the input level (Normal, Low
Noise, Low Distortion) as set in the Analyzer tab of the
Connection Control menu (see section Table-Oriented
Version on p. 4.73 ff.)
Freq. Offset Frequency offset compared to the nominal channel frequency
Chan./Trig. Slot Offs. RF channel and trigger slot offset (see Trig. Slot Offset
hotkey on p. 4.18 )

nd
parameter
line
The second parameter line contains the following marker values:
Level and time of reference marker
Level and time of delta marker 1 (setting absolute ) or difference
from reference marker (setting relative )
Level and time of delta marker 2 (setting absolute ) or difference from reference
marker (setting relative )
Info box
The info box contains the following settings:
Sym. Offset Time Delay set by means of the Display/Marker softkey: Number
of symbols that the burst is shifted with respect to the time axis
and the tolerance template. In
Signalling mode, the measured
timing advance error is displayed instead.
Statistic Count Number of bursts per statistics cycle, as set in the Control tab of
the Power Configuration menu.
In addition, the following scalar results are indicated:
Avg Burst Power Average burst power, depending on the display mode set (see
upper right corner of the diagram).
TSC detected Training sequence of the measured RF burst (GSM – 0 to 7 |
Dummy | --- .
Out of Tolerance Relative number of bursts that are out of the tolerances defined
by the limit lines.
Burst Matching Error message if the displayed curve is out of tolerance.
Remote control
Settings are retrieved using the query corresponding to the setting command
(setting command with appended question mark).
