This is regarding multi-carrier GSM measurement using PXA. In the SWT/EVM menu, have noticed an option “Carrier BPF Auto, Single and Multi”. Could you please explain this?. Noticed big improvement in muti-carrier SWT measurement with this carrier BPF enabled. For example 6C configuration with 7 MHz carrier spacing, GSMK SWT @1200 KJz showed an improvement of around 6 dB!! Wnat to know what is really happeneing with this option ?
