Exercise – Using the Trace Record Waterfall To Detect Intermittent
Transmitters
The Trace Record Waterfall allows for detailed trace recording and analysis. During the Trace Record, all
of the collected trace information, including a timestamp, is saved, so that each trace can be analyzed at
a later time. For this exercise, we will learn how to setup the Trace Record Waterfall and how to review
it after recording.
For this example, the recording was set for 24 hours. During those 24 hours, both a frequency hopping
transmitter and a burst transmitter were turned on at separate times. You could simulate this in your
exercise by turning a transmitting signal on/off, such as a cell phone or a baby monitor, during the
waterfall recording.
Press the Power button to turn the unit on.
Press F4 or select Waterfall from the main menu.
Press F2 or select Trace Record from the Waterfall
sub-menu.
Select the Record icon from the Trace Record Sub-
menu.
A dialog box will appear, allowing you to adjust
the settings for the Trace Record session. The
illustration to the right shows the settings that
were used for this exercise.
It is important to note that the memory
required to store your trace recording will vary
depending on the frequency range, trace
interval, and total time settings. The estimated
required disk space is displayed at the bottom
of the dialog box. The OSCOR will not allow the
recording to start if this exceeds the free space
available on the USB drive or CF card that is
inserted.
Press OK.
