Application Notes

Interference hunting in TDD networks

In time division duplex (TDD) networks, the downlink (DL)
and uplink (UL) use the same frequency band in different
timeslots. When viewing such TDD signals on a conventional
spectrum display, it is impossible to differentiate the
two as well as any other unwanted signals present in the
same spectrum. This makes interference hunting extremely
difficult.

The R&S®PR100 portable receiver, the R&S®MNT100 RF interference
locator and the R&S®DDF007 portable direction
finder provide a trace minimum hold function with adaptive
detector that enables users to effectively suppress
TDD signals and show persistent interferers on the spectrum
display.
