10 Tap PDSCH, and then select the PDSCH modulation type option: Auto, QPSK,
16 QAM, 64 QAM, 256 QAM, LTE E-TM3.3, LTE E-TM3.2, LTE E-TM3.1a, LTE
E-TM3.1, LTE E-TM2a, LTE E-TM2, LTE E-TM1.2 or LTE E-TM1.1.
If two or more modulation types are used in a frame, select Auto. If the PDSCH
uses the same modulation type in a frame or in a subframe, select a specific
modulation type to get more accurate EVM.
11 Tap PDSCH Threshold to set the threshold for PDSCH and enter a value by

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.
