Result display
Channel detection threshold
On the trace, some peaks corresponding to noise could be mistaken
for channels. It is therefore necessary to introduce a power threshold
level: only peaks that exceed this threshold will be considered as
channels and included in the table of results. To display or modify
this threshold, press the
SETUP key, then select Signal threshold
in menu measurement. Select ‘auto“ or a insert a fixed threshold
value. When set to Auto, the signal threshold is calculated from
the actual trace.
Display of a grid
The graph window can include a grid to facilitate verifi-
cation of the position of the channels. Several grids are
possible (see the
chapter “Grid” on page 21 ).
Multiple traces (Overlay)
The Overlay functions allows you to display multiple
traces in one view and to compare them.
Note: The Overlay function is not available in Drift mode.
To add a new trace:
1. Navigate to page 2 of the softkeys on the right
side, then select Overlay.
2. Press the Set New Trace softkey.
copy of the previously active trace is added to the display. A
new number is added to the trace tab line.
3. Start a new measurement or open the File menu
and select a trace to be loaded.
The selected trace is overwritten by the new one.
