● Stop
Click the button in this column to stop recording the wanted signal prematurely. If the
specified number of measurements has been made, recording of the user data signal stops
automatically.
● Displayed Samples
Select how many measurements will be shown in the graphic.
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 loss of the user data signal always occurs at the same position.
● Selective measurements at a fixed position should be made over a longer period of time.
Procedure
1. Enter the time interval between two measurements.
2. In "Samples" enter the number of measurements.
3. In "Displayed Samples" select how many measurements will be shown in the graphic.
4. Click the "Start" button.
The status (to the right of the graphic) indicates whether the signal recorder is running. The
