Sweepless sweep allows you to get sweep information even if no transmitter

is available. In Sweepless sweep, the SDA-5000 measures the stable carrier

levels and memorizes them. You can then compare these levels with the

levels of the same carriers at a different point in the network, and the

differences in frequency response can be highlighted.

After connecting to the test point and calculating test point loss as described

in “Test Point Compensation Configuration” (page 60), enter the main

SWEEP menu and use the up and down diamond keys until Sweepless

appears in the Edit Box.

With sweepless sweep selected, the sweep display measures active carriers

to create the sweep response. When sweep is first entered, the first set of

sweep readings will be used as a “NONE” reference. This is just a startup
