output ports and both channels equally. After selecting the antenna type, placement, and RF cable used to route the

antennas to the Antenna Distribution System, it’s important to optimize the RF signal level going into the receivers for best

signal‐to‐noiseratio.

setup, use multiple levels of antenna distribution systems to allow adjustment of the RF gain across groups of receivers

as needed. Use the RF History Plot tool in Wireless Workbench for increased control and accuracy of RF gain adjustment

and to refine antenna placement across the venue.

Use RF History Plot tool to map the signal level received from the transmitter at any point in the venue and over time.

Open the RF History Plot tool from Wireless Workbench, select the receiver channels you want to plot from the interface,

and click start. Use this tool to see the signal level at each antenna as you walk the venue floor or perimeter and then use

this information to adjust the RF gain and antenna placement if needed. Use the RF History Plot tool with the transmitter

Off to see a time history of the channel background noise level.
