When NR is selected as Technology, do the following steps:
–
4
Tap Antenna Port to assign an antenna port number automatically or manually,
and select from Auto, Antenna 0, or Antenna1.
If the MIMO is set to 2x2, the antenna ports 2 and 3 are disabled.
5
Tap to switch CFI to Manual or Auto.
–
–
6
Tap CFI and input a value from 1 to 3 as desired using the on-screen keyboard.
7
Tap SSB frequency and input the value using the on-screen keyboard.
8
Tap GSCN and input the value from 2 to 26639 using the on-screen keyboard. If
you need to search SSB based on ARFCN raster, it would take too long time
since ARFCN raster is very narrow. Therefore, it is recommended that you define
a SSB searching frequency in wider steps. This is the usage/purpose of GSCN.
You can search the frequency corresponding to GSCN in maximum 100 MHz
bandwidth of ARFCN that SPA06MA-O supports.
9
Tap PCI (Physical Cell ID) and select between LTE PCI and NR PCI.

duration is a higher layer parameter configured either as Normal or Extended
that says the demodulator how many symbols per subframe are used by
PHICH.
Normal: There are 8 PHICH sequences in one PHICH group (4
-
symbols).
-
Extended: There are 4 PHICH sequences in one PHICH group (2
symbols)
Select Sub-Carrier Spacing as 15 kHz (Case A). The standard for NR SCS is
15 kHz. The instrument supports 15 kHz of sub-carrier spacing.
Auto lets the instrument set the number of OFDM symbols used for transmit-
ting PDCCHs in a subframe.
Manual sets the number of OFDM symbols manually. The set of OFDM
symbols that can be used for PDCCH in a subframe is given by 0, 2, 3 or 4 in
1.4 MHz bandwidth and 1, 2 or 3 in other bandwidths.
NOTE
Based on the GSCN input frequency, the SSB Frequency is automatically
changed.
Tap to switch LTE PCI Mode to Manual or Auto and input a value from 0 to
503.
The PCI switches to Manual.
Tap NR PCI Mode to Manual or Auto and input a value from 0 to 1007.
The PCI switches to Manual.
NOTE
You can set Auto to let the instrument detect the Physical Cell ID for the LTE/
NR signal automatically and Manual to set the specific Physical Cell ID for the
LTE/NR signal manually in order to speed up the synchronization with a BTS.
