BG95-M1 Factory Test Mode Tx Waveform

IoT Modules LPWA Module

Hello,

I am currently using the BG95-M1 Evaluation kit and in Factory test mode I am generating a signal and measuring it with NI VST/RFmx LTE. The EVM measurements do not look good (getting 15% mean rms EVM). We are also getting similar results with a Keysight instrument. I wanted to check what type of performance should be expected in the Factory Test Mode? The FTM manual I am using is: https://www.quectel.com/wp-content/uploads/2021/03/Quectel_BG95BG77BG600L_Series_FTM_Application_Note_V1.0.pdf

Best Regards,

Under FTM mode ， The Main Target is testing the TRP and TIS

pls ignore [NI VST/RFmx LTE] first
