1. Press the [LINE] key.
2. Select the "Upper Limit" or "Lower Limit" softkey.
The R&S Cable Rider ZPH opens an input field to define the limits. Signals that are
above the upper limit and below the lower limit are ignored. Only the signals within
these boundaries are considered in the analysis.
The limits that you have defined are displayed in the power bar as red triangles.

Collecting Map Data
Geotag
A geotag is a tag for a particular location that contains information about that location.
This information includes, for example, GPS coordinates, the time of the measurement
or level that has been measured. You can evaluate the geotag information directly
onsite or save the information for later evaluation.
With the geotagging functionality, you can mark locations where you have performed a
measurement. Thus, you are able to analyze the geographical distribution of the
received signal strength. This allows you to analyze, for example, the coverage condi-
tions around a base station's coverage area.
In the map display, a geotag is displayed as a dot with
color indication
to show the sig-
nal strength measured in that location. Equipped with option R&S ZPH-K15, the geotag
provides also an azimuth reading which shows a straight line. This straight line repre-
sents the direction you are facing.
The azimuth is the deviation from the direction you are facing and the north. It is a
number in degrees. For example, if you are looking east, the azimuth would be 90°.
The application shows the azimuth as a straight black line, beginning at your location
and pointing in the direction you are facing. The azimuth line is always displayed when
you are using the functionality of the R&S ZPH-K15, even if you are just walking
around without saving any data.
The R&S Cable Rider ZPH provides three map applications:
triangulation
,
outdoor
mapping
and
indoor mapping
. The following chapters describe the various ways how
map data can be collected and display in these map applications.

Outdoor Mapping
In the outdoor mapping application, you perform the collection of geographical data
with directional antenna a R&S HA-Z340 GPS receiver. The GPS receiver is not
required if the R&S HL300, R&S HE300 and R&S HE400 antenna are used.
