5GNR Summary and Multi PCI
5GNR summary measurements are used for compliance testing of 5GNR networks and can evaluate active antenna systems for beamforming profiles and dynamic physical layer attributes of the transmitted signal. Remote Spectrum Monitor can analyze a single physical-layer cell or multiple physical-layer cells at one time. The following considerations apply to each measurement.
Single PCI:
Better for conducted measurements, directional antenna measurements, or if only one cell is present.
Only one cell is reported. If multiple cells are present, the analysis may jump to different cells or not analyze any of the cells.
Multi PCI:
Better sync in over the air field conditions.
Multiple Cells can be reported and sorted on various measurement parameters.
This section illustrates several 5GNR summary measurements using both single PCI and multi PCI analysis techniques.
5GNR Summary Multi Beam View
The following measurement is set up to display 5GNR summary data in a multiple beam view. In multi beam view, a maximum of eight beams can be displayed at once on a single page. Remote Spectrum Monitor can capture data for as many as 64 beams in a total of eight pages.
5GNR Summary – Multi Beam View
1. 5GNR Analyzer Status Panel: Each measurement features a unique status panel that displays settings and information relevant to the current measurement and view settings. This panel provides quick access to the measurement frequency, subcarrier spacing, channel bandwidth, and band configuration. See .
2. PAGE: This field indicates the current multi beam page. A maximum of eight pages (numbered 1 through 8) with eight beams (numbered 0 to 63) on each page can be displayed in multi beam view. You can cycle through the pages using the left/right (</>) arrows or touch the number to select the desired page.
3. MIN EVM BEAM: This field shows which beam measures the lowest error vector magnitude (EVM).
4. SINGLE/MULTI BEAM: This field shows the current view setting. Touch this field to toggle between SINGLE BEAM or MULTI BEAM views. You can also change the view setting from the MEASURE menu.
5. SYNC/DEMOD: Valid 5GNR measurements require the signal synchronization and demodulation. The indicators here solid green when the received signal is synchronized and properly demodulated, indicating that you have a valid measurement.
6. Summary Data: For each beam, the following synchronization signal summary data is displayed:
SS-RSRP: Secondary synchronization signal reference signal received power measured in dBm.
SS-RSRQ: Secondary synchronization signal reference signal received quality measured in dB.
SS-SINR: Secondary synchronization signal-to-noise and interference ratio measured in dB.
7. Beam Display: This area shows the received signal strength of each beam as a vertical bar. The top of the bar is annotated with the maximum signal strength (in dBm). The number of beams displayed depends on how many beams are defined by the band configuration. From 1 to 8 beams can be displayed at once on a page. When more than 8 beams are measured, additional beams can be accessed from additional pages. The beams are numbered from 0 up to 63. If you touch a beam, the view changes to display the selected beam in single beam view.
8. PCI Summary: This area shows the physical cell ID summary data, including the sector ID, cell group number, frequency error, time offset, and sync status. Also noted is the instrument’s reference clock accuracy of Internal, External, or GPS high accuracy (requires GPS).
 
5GNR Summary Single Beam View
5GNR summary measurements in single beam view provide the same information as the multi beam view with added measurements as described in Figure: 5GNR Summary – Single Beam View.
5GNR Summary – Single Beam View
1. 5GNR Analyzer Status Panel: Each measurement features a unique status panel that displays settings and information relevant to the current measurement and view settings. This panel provides quick access to the measurement frequency, subcarrier spacing, channel bandwidth, and band configuration. See .
2. BEAM: This field indicates the current beam summary page. A maximum of 64 beams (numbered 0 to 63) can be individually displayed in single beam view. You can cycle through the beam pages using the left/right (</>) arrows or touch the number to select the desired beam.
3. MIN EVM BEAM: This field shows which beam measures lowest error vector magnitude (EVM).
4. SINGLE/MULTI BEAM: This field shows the current view setting. Touch this field to toggle between SINGLE BEAM or MULTI BEAM views. You can also change the view setting from the MEASURE menu.
5. SYNC/DEMOD: Valid 5GNR measurements require the signal synchronization and demodulation. The indicators here blink green when the received signal is synchronized and properly demodulated, indicating that you have a valid measurement.
6. Channel Summary: For the current beam, shows the average error vector magnitude (EVM), peak EVM (@ subcarrier/symbol) and received power in dBm for each block measurement:
PSS: The primary synchronization signal provides the primary frame boundary
(i.e., the position of the first symbol in the frame).
SSS: Similar to PSS, the secondary synchronization signal provides the secondary sub-frame boundary.
PBCH: This is the physical broadcast channel, the main purpose of which is to carry the broadcast master information block.
PBCH-DMRS: In 5GNR measurements, the PBCH decoding relies on a demodulation reference signal (DMRS, which is a physical layer reference signal used for decoding) rather than a cell specific reference signal (CRC).
7. Sync Signal (SS) Summary Data: Shows the following synchronization signal summary data for the current beam:
SS-RSRP: Secondary synchronization signal reference signal received power measured in dBm.
SS-RSRQ: Secondary synchronization signal reference signal received quality measured in dB.
SS-SINR: Secondary synchronization signal-to-noise and interference ratio measured in dB.
8. PCI Summary: This area shows the physical cell ID summary data, including the sector ID, cell group number, frequency error, time offset, and sync status. Sync status can indicate if there is a PSS, SSS, or Beam Index failure, Full Sync, or an Unknown condition. Also noted is the instrument’s reference clock accuracy of Internal, External, or GPS high accuracy (requires GPS).

Status Panel (5GNR Summary and Multi PCI Measurement) 
 
SWEEP: Toggles the current sweep setting between continuously or sweep once.
SWEEP ONCE
When sweep is set to single sweep, SWEEP ONCE updates the measurement display. Data continues to be captured in the background.
BAND
Select MANUAL, Global All or one of the predefined bands. Selecting MANUAL disables the ARFCN and GSCN settings.
ARFCN
ARFCN is the Absolute Radio Frequency Channel Number. The ARFCN is a unique identification number assigned to each radio channel within a communications spectrum. The ARFCN can be used to calculate the center frequency of the radio channel. The available input range is dependent on the selected band. ARFCN is activated when the BAND is set to a predefined band or Global All.
CHANNEL BW
Sets the measurement channel bandwidth. The available bandwidth settings depend on the selected band and bandwidth option installed in the instrument. Refer to Options Settings.
GSCN
GSCN is the Global Synchronization Raster Channel. The GSCN identifies the mapping of the synchronous signal block (SSB). The available input range is dependent on the selected band. GSCN is activated when the BAND is set to a predefined band or Global All.
SUBCARRIER SPACING
Sets the subcarrier spacing. The available input range is dependent on the selected band.
CENTER FREQUENCY
When the band is set to MANUAL, sets the center frequency of the measurement channel. Changing the center frequency sets the band to MANUAL.
SSB OFFSET
SSB is the Synchronous Signal Block. The SSB Offset sets the frequency offset between the SSB and the overall resource block.
FREQ REFERENCE
Indicates the current frequency reference source of Internal, External, or GPS Hi Accuracy (requires GPS). The instrument automatically selects the frequency reference in the following order of priority: external, GPS, then the internal time base.
