2.4 GHZ BAR GRAPH
This screen displays any 2.4 GHz access point's out-
put in dBm using a horizontal graphical bar. When a
bar graph measurement is started, it will run until the
measurement is changed or the unit is turned off. The
last measurement selected is restored when the unit is
turned back on. The bar graph measurement continu-
ally monitors the RF input connected to unit. When a
packet is detected that is above the set threshold, a
bar is displayed whose length is proportional to the
measured signal strength of the packet. The threshold
is marked by the down arrow above the signal strength
bar. This packet threshold is adjusted by pressing the
UP and DOWN keys while the measurement is dis-
played.
The current signal strength is displayed in
text in the lower left corner of the screen. This signal
strength text is always updated, even if a packet is not
detected. The highest level measured when a packet
is detected is marked by the Up arrow and wavy line
