Adjust the Timespan to select the range of time in
which the amplitude was the highest (most red). Since
the software continuously logs data from the Wi-Spy,
we can zoom-in to view just the minute when the
transmitter was within close range.
A shorter timespan helps users identify what type of a
device was transmitting. Once the Timespan is
shortened, we see three spikes of activity above Wi-Fi
Channels 8 and 9.
Using the signatures tool, we can match the recorded
pattern to an AV transmitter. Click on the signatures
box and then hover the mouse over the pattern in the
Density View. Click the box again to turn off the
silhouette.

The standard antenna in most spectrum analyzers and Wi-Fi receivers is omnidirectional. Omnidirectional
antennas receive almost indiscriminately on a horizontal plane, whereas a directional antenna is used in a
similar manner to a flashlight – point it to gain visibility in that specific direction.
