Transmitter spurious emissions with 5G TM
NOTE:
You can only set the frequency range and attenuation by tapping the Configuration icon. If you select the first icon
next to the Range table above, it only shows the selected range and if you select the second icon next to the Range
table, it keeps moving from the first selected range to the final selected range.
Conducting transmit on/off power
Transmit on/off power
Transmitter OFF power is referred to as the mean power measured over 70 us filtered with a square filter of bandwidth equal to the
transmission bandwidth configuration of the BS centered on the assigned channel frequency during the transmitter OFF period.
Transmit OFF power requirements apply only to TDD operation of the BS.
Setting measure setup
Before starting the measurement, you need to set Spectrum measurements displayed on the quick access and display tab. See
"
Configuring Spectrum Measurements " for more details. The measurement settings can be saved and recalled as a file by selecting
File Type as Setup and load the file onto the instrument using the Save/Load icons on the side bar.
1 Tap the Setup ( ) icon on the side bar.
2 Tap Radio Setup then the Radio Setup pop-up window appears, if you choose FR1 , select from the following:
a SCS 15 kHz: 5, 10, 15, 20, 25, 30, 40, 50 MHz
b SCS 30 kHz: 5, 10, 15, 20, 25, 30, 40, 50, 60, 70, 80, 90, 100 MHz
c SCS 60 kHz: 10, 15, 20, 25, 30, 40, 50, 60, 70, 80, 90, 100 MHz
d Tap
Duplex Type
between
FDD
and
TDD
as required.
- FDD : both uplink and downlink can transmit at the same time at different spectrum frequencies
- TDD : both uplink and downlink use the same spectrum frequencies but at different times
