4.4 Testing the Gate Antenna
After tuning the gate antenna, you can check for proper function using the Reader, the ISOStart
service software and a Smart Tag. Here the Noise Level and performance of the gate are tested.
4.4.1 Checking the Noise Level
Step
Action
Note
1
Activate “Test and
Measurement”

Select „Noise Level“ and
start by clicking on „Start“

Normal Noise Level values:
Average:
< 50mV
Difference (Max-Min):
< 30mV
If the values are not met, check the following:
•
Are all cables pulled tight and do they make good contact?
•
Were the ring cores installed in the antenna cable?
•
Were the cables routed as specified?
•
Are other RFID systems installed nearby?
•
Are there large metal parts near the antenna (distance < 1.0 m)?
•
Are there devices nearby which may emit noise interference (larger machines or wireless
devices)?
•
Are there interference from the mains?
To determine which devices may be disturbing the gate, briefly disconnect them from the mains.
