Using FPH Gated Trigger Settings For a Live 5G Signal
To look at uplink activities (wanted and unwanted)
For TDD networks, the downlink and uplink signal share the same frequency band. They are divided by time (using different time slots). When using an analyser in frequency mode, the downlink would mask any uplink activities, being the dominant signal. Hence it is quite difficult (if not impossible) to see any uplink signals and possible interference sources. With R&S®Spectrum Rider FPH or R&S®Cable Rider ZPH (v.12 model with ZPH-K1 option) gated trigger feature, it is possible to mask out the downlink signal and focus on the uplink activities.
