▪
SCS 30 kHz: 5, 10, 15, 20, 25, 30, 40, 50, 60, 70, 80, 90, 100 MHz
▪
SCS 60 kHz: 10, 15, 20, 25, 30, 40, 50, 60, 70, 80, 90, 100 MHz
▪
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
If you select the operating frequency as FR2 , select from the following:
▪
SCS 60, 120 kHz: 50, 100 MHz
▪
You can only select the Duplex Type as TDD .
3 Based on the above setting, tap Test Model FR1 and select the options from the following choices: FR1-TM1.1, FR1-TM1.2,
FR1-TM3.1, FR1-TM3.1a, FR1-TM3.2, FR1-TM3.
4 Based on the above setting, tap Test Model FR2 and select the options from the following choices: FR2-TM1.1, FR2-TM2, FR2-
TM3.1.
Setting limit
1 Tap the Menu > Limit on the side bar.
2 Tap to switch the Test Limits to On or Off to enable or disable Pass/Fail indication.
The result table color for Pass is green, and the result table color for Fail is red.
3 Tap High Limit to set the upper threshold using the on-screen keyboard.
4 Optional . Tap the Save icon on the side bar and select the save option form the choices available for your measurement mode.
Occupied bandwidth measurement with 5G TM
The Occupied Bandwidth measurement shows both of power across the band and power bandwidth in a user specified percentage
to determine the amount of spectrum used by a modulated signal. Occupied bandwidth is typically calculated as the bandwidth
containing 99% of the transmitted power.
ACLR
The Adjacent Channel Power Ratio (ACPR) designated by the 3GPP WCDMA specifications as the Adjacent Channel Leakage
Power Ratio (ACLR), is the power contained in a specified frequency channel bandwidth relative to the total carrier power. It may
also be expressed as a ratio of power spectral densities between the carrier and the specified offset frequency band.
