Overall, the idea is to reduce the affects of the noise above by either reducing the noise at the
source or desensitizing our system to the source of noise. The following sections explain the
appropriate tuning procedure(s) when a given type of noise is present.
Note: During installation leave the Sam Option "Enable Sweeper Immunity" off until the system is tuned so
that DMS A view accurately shows any interfering noise characteristics. After the system is tuned, this
option can be turned on.
Analog View
DMS offers a display that shows real-time data to assist the technician in adjusting the Reader for
optimal performance. Analog View is best for observing short duration noise, as well as stationary
environmental resonances.
For multi-antenna systems, signals from primary and secondary antennas are displayed on the left
and right. In the Analog View, four (4) different points within the signal processing chain can be
viewed. The Filter View switch controls which level of signal processing is displayed.
Typical Tuning Procedure
Since no real-world environment is free of random noise and resonances, tuning may be required.
This may involve adjusting TX Power, RX Gain and RX Hardware gain for the system antennas in
the following order:
3. Adjust TX Power for the antennas according to the regulation maximum. For best
performance, TX Power should be set equal for both pedestals.
4. Flip to View D and adjust RX Gain individually for each pedestal, until the noise floor
disappears under the Analog View.
5. Flip to View C and adjust RX Gain individually for each antenna until empty spots occur
(see notches in graph), indicating disappearance of background resonances. Because of
the natural resonance for the TR4215, the view should look like Figure 6.1. The RX
Hardware gain usually does not need to be adjusted (and remains set at 31).
