Tuning AM
The ARGUS AM Floor System is performing at its best when maximum power is being
transmitted at 58kHz. The Tuning screen shows a graphical display of the transceiver
antenna tuning.
Figure 49: Tuning AM
Be aware of the high antenna voltages! Do not touch the backside of the
PCB or the metal tuning jumper pins when the board is powered, as this
might result in you receiving an electrical shock!
When the Tuning screen is open, detection of tags is disabled. Make sure
to switch to another screen if you want to test the detection performance!
By changing the positions of the antenna jumpers on the Control Unit board, you can find
the positions for both coils where they have the highest voltage output at 58kHz (the vertical
red line). The spot where the curves cross the red line is the actual transmitted power. A
higher output will increase the performance of the ARGUS AM Floor System, where a lower
output will result in less performance.
To better view the tuning signals, click the “Maximize bottom panel view” button to view the
tuning signals full screen like in Figure 50.
