Step 3 – Running a horizontal scan

Tips for using the antenna handle key and device buttons

Horizontal scan can be operated via the key on the antenna handle or via the buttons / keys on the device. In most cases using the key on the antenna handle is more convenient. On the other hand, some functions are only available via the buttons and keys on the device.

Following tables explains the functions of the key and the respective buttons.

In the following actions only the usage of the key of the handle is described were available. You may also use the buttons and keys of the device as described in the table above.

While measuring the results are permanently recalculated and displayed in the polar chart by the yellow arrow as well as in the right Calculated column. Following figures are calculated:

      Azimuth: The direction of the calculated signal.

      Elevation: The angle above the horizon.

      Polarization: The orientation of the wave, e.g. H + 10° means horizontal plus 10 degrees.

Running a Continuous horizontal scan

1.   Tap the Scan Type button and select Continuous from the dropdown list.

2.   Press the key on the handle to start the measurement.

3.   Turn around 360° slowly. Watch the spirit level and make sure that the antenna is properly oriented, both horizontally and vertically.

4.   Turn around 360° again in the opposite direction.

5.   Press the key on the handle to stop the measurement.

Running a Discrete horizontal scan

1.   Tap the Scan Type button and select Discrete from the dropdown list.

2.   Press the key on the handle to start the measurement.

3.   Turn around and press the key on the handle. With each press a value is added to the scan. Watch the spirit level and make sure that the antenna is properly oriented, both horizontally and vertically.

4.   Long press the key on the handle to stop the measurement.

Running a Discrete with Max Hold horizontal scan

1.   Tap the Scan Type button and select Discrete with Max Hold from the dropdown list.

2.   Press the key on the handle to start the measurement.

3.   Turn around and wait for the maximum power level.
Watch the spirit level and make sure that the antenna is properly oriented, both horizontally and vertically.

4.   Press the key on the handle twice: The first press resets the max hold of the previous value, the second adds the new value. Add further values in the same way.

5.   Long press the key on the handle to stop the measurement.

Restarting the measurement

Tap the Restart button

Resetting the measured maximum power level

The maximum power level is represented by the orange line in the power level bar.

Tap the Reset Max button.

Manually correcting a result

Sometimes it may be necessary to manually correct the calculated result (e.g. due to reflections).

To correct a calculated result:

You stopped the scan.

1.   Point the antenna to the wanted direction.

2.   Tap the Manual Correction button.

The result is replaced by the current antenna direction.

The button now shows Calculated Result.

3.   To recall the calculated result tap the Calculated Result button.

Again, the calculated result is displayed.

Resetting a calculated result

Tap the Reset button.

The results in the polar chart and in the Calculated column are deleted.
You may now start a new scan.
