3. To change the squelch threshold, highlight Squelch and press the right arrow ( ) to edit
the threshold. Highlight each digit you want to edit and scroll up and down to change the
threshold to a value between 0 to 9999 μV/m.
4. Press
Enter

↵
) to save the new value. The cursor automatically returns to the left column.
Press
Esc
to return to the settings menu and continue configuring other parameters.
Press
Esc

3.2.7 Setting up Units
The DRV3 can display leakage levels in two different measurement units, in μV/m or dBμV/m.
The most common unit used to measure signal leaks is μV/m (microvolts per meter) and this
is DRV3’s default setting. Note that the squelch feature will always be calculated in μV/m.
However, the DRV3 will apply the units of measure to the snapshot feature (see section 4.3
Using the Snapshot Feature on page 33), depending on which units you have selected.
To change the units of measure:
1. In the settings menu (page 2), select Units.
2. Press the right arrow ( ), then toggle between μV/m and dBμV/m using the up and down
arrows.
3. Press
Enter
(
↵
) to save your choice. The cursor automatically returns to the left column.
4. Continue editing other parameters, if desired, or press
Esc
to return to measurement
mode.
3.2.8 Setting up Frequencies
You can configure three (3) preset leakage monitoring frequencies for each of the DRV3’s
bands. These frequencies vary from one operator to another and can vary within different
areas of the operator’s network. Make sure that the frequencies you configure in the DRV3
match the leakage monitoring pilot signals used by the operator.
NOTE
Selected frequencies and tagging parameters must match the ones used with
the DSG1, installed at the headend, in order to obtain leakage measurements.
