BRING-UP AND TESTING
LTE RF PERFORMANCE TEST
36 PROPRIETARY MODULE INTEGRATION GUIDE
SEQUANS Communications
5.5.2 Procedure
1. Apply the power from the local Host to the VZM20Q.
2. Launch DVTool on UART2. Guidelines for using DVTool can be found in
document 4G-EZ DV Tool User Manual.
a) Ensure that the external RF losses from VZM20Q to MXA / MXG are
configured into DVTool
b) Perform the Rx and TX Screening
3. Change DV Tool configuration so as to perform Rx test in each band at
mid-frequency and mid input level (typically -60 dBm), and check the
usual criteria on RSRP and CINR for RX.
Notes:
• DVTool contains a board suite of RF test tools to help validate the RF
performance against the 3GPP test specification. It is highly recommended
that once the screening is validated a full DVTool test campaign is
performed for both RF bands. This should include releasing such results to
Sequans for qualification.
• Final product pre-conformance test at a reputable test facility to test stan-
dards TS 36.521-1 & 36.521-2 is further recommended in advance of final
conformance test requirements. Releasing results to Sequans for checking
is also highly recommended.
5.5.3 Troubleshooting
Note: The most frequent problems that can occur at this stage either can
be solved with recommendations deduced from other sections in
this document, or will be provided in a future edition of this docu-
ment.
