Berkeley Varitronics Systems Wi-Fi Power Analyzer, Manual

Page: 22 / 39

Narrow and Wide IF radio buttons indicate the IF filters being used by the current measurement.
Clicking these radio buttons has no effect as they are used only to display the current Wi-Fi Power
Analyzer status.
The unit text portion displays the same information as the Wi-Fi Power Analyzer “Unit Data”
Selection Menu entry. The square green Wi-Fi Power Analyzer LED is lit when unit data has been
retrieved from the Wi-Fi Power Analyzer. To retrieve unit data from the Wi-Fi Power Analyzer, click
the “Get Unit Data” button below the unit text box.
Measurement Graph
Figure 23
dBm data from all of the Wi-Fi Power Analyzer measurements is displayed in a bar graph as in
figure 23. The Y axis is scaled by dBm while the X axis displays the frequency in MHz for each bar.
This graph is filled in as the Wi-Fi Power Analyzer measures frequencies. Since the Wi-Fi Power
Analyzer measures frequencies in an ascending order, the graph is built from right to left when-
ever a new measurement is started on the Wi-Fi Power Analyzer. The type of measurement being
preformed by the Wi-Fi Power Analyzer along with the PC real time is displayed above the graph
with the owner of the Wi-Fi Power Analyzer (from the unit data). The Wi-Fi Power Analyzer below
the graph “crawls” each time the PC receives data from the Wi-Fi Power Analyzer or from a replay
file. A threshold is used to display the frequencies along the X axis. This threshold can be adjusted
using the up-down frequency display threshold control below the graph. If the PC is connected to a
printer, the graph can be printed (in black and white) by clicking the “Print Graph” button.
