Ghz Line Graph - Berkeley Varitronics Systems Butterfly Manual

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
below signal strength bar. This indicator stays at the
position of the strongest packet signal until the mea-
surement is changed or restarted.

5 GHZ LINE GRAPH

This screen displays any 5 GHz (802.11a) access
point's output in dBm (vertical) graphing power over
time (hrozontal) in milliseconds (scrolling from left to
right). As with the bar graph when selected, the line
graph will run until changed or the unit is shut off. If
the unit is shut off while displaying a line graph mea-
surement, the line graph measurement will resume
when the unit is next turned on. The line graph mea-
surement (as the bar graph measurement) continually
monitors the RF input and displays this input when a
packet is detected that is greater then the threshold, in
this screen the threshold is displayed as a dotted line.
To adjust this threshold, press the UP and DOWN keys
while the measurement is displayed. The current RF
power measured during the line graph measurement is
displayed in text in the lower left corner of the display.
As in the Bar graph, this value is always updated, even
if a packet is not detected. For both the bar and line
graph measurements, if the total power displayed in
the lower left corner is changing but no bar or line is
displayed, reduce the packet detect threshold by press-
ing the DOWN key.
