●
Start
Click the button in this column to start recording the wanted signal.
Note
•
If you start a new recording, the previous recording will be overwritten.
•
If the recording has lasted less than 10 minutes and has not yet been completed (e.g.
due to a restart or power down), the measured values are deleted.
The signal recorder saves the recorded data automatically every 10 minutes. Following a
restart, the recording contains all the values up to the last save action.
●
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 losses of of the user data signal always occur 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 first measured value is displayed only after the set time interval has elapsed.
5.
To stop the recording, click the "Stop" button.
