● Start
Click the button in this column to start recording the signal strength.
Note
• If you start a new recording, the previous recording will be overwritten.
• When the device restarts, the measured values are deleted.
● Stop
Click the button in this column to stop recording the signal strength prematurely. If the
specified number of measurements has been made, recording of the signal strength
stops automatically.
Notes on usage
Note the following tips that will help you to obtain useful measurements with the signal
recorder:
● Set a fixed data rate on the access point.
● If you have activated iPCF, set as low a cycle time on the access point as possible for the
measurements.
● Make sure that there is enough data communication during the measurement because
the statistics functions evaluate incoming data frames.
● The measurement path should be traveled 2 to 3 times with the same parameters to find
out whether losses of signal strength always occur at the same position.
● Selective measurements at a fixed position should be made over a longer period of time.
Note
• If you start a new recording, the previous recording will be overwritten.
• When the device restarts, the measured values are deleted.
Procedure
1. Enter the values required for the interval between two measurements and the number of
measurements.
2. Click the "Start" button, the display "started" appears in the "Status" column.
3. When "stopped" is displayed again in the "Status" column, recording of the signal
strength has been completed.
4. Change to one of the following menu items to call up the result of the recording:
