For the RM500Q series / RM502Q-AE each of the RSRP, RSRQ, SINR AT commands have PRX, DRX, RX2 and RX3 paths. Please could explain the meaning of PRX, DRX, RX2 and RX3?
RX2 and RX3 seem to not give valid responses.
I get answers like:
+QRSRP: -98,-96,-140,-140,LTE
+QRSRQ:-12,-13,0,0
+QSINR:16,15,0,0
Hi, Herbert,
is MIMO-RX2 the same as PRX MIMO and MIMO-RX3 corresponds to DRX MIMO? We are using the RM520N-GL Modem in 5G NR mode in band n78.
The RM520N-GL Hardware Design Manual (Pages 52, 53) doesn’t know RX2 and RX3 and I want to know the relation between Antenna connector and received signal.
Sorry for the inconvenience, but this document (Quectel_RG50xQ_Series_Hardware_Design_V1.3.pdf) does not contain any information about the RM520N modem.
