RF Signal Measurement Mode
The RF Signal Measurement Mode is the default display mode for leakage testing and is
used to accurately determine the strength of a leak, pinpoint its location, and provide a
leakage value for documentation. Measured RF leakage values can range from 0.1 to 2000
µV/m and are displayed in large, easy-to-read numbers. A bar graph at the bottom of the
display illuminates proportionally to the signal strength of the leak.
Additionally, an audible tone will sound if the measured signal breaks squelch. The signal
breaks squelch when the RF leakage is greater than the squelch level and tag qualifiers are
also met. This tone can be used to help locate the potential source of the leak.
When the Signal Level display is selected, the Antenna icon flashes as indicated by the red
circle in the following images.
When using a CT-4 installed in the headend, the measurement
range for in-home leakage is 20 to 2000 µV/m.
When using a Seeker D Lite Source Transmitter, the
measurement range for in-home leakage is 0.1 to 20 µV/m in
home cert mode.
