Dear all, I plan to use 2 USPRs to analyze LTE signal. One will use a GPSDO to have a good clock and time reference. To have synchronization between them, the second one will be set on external synchronization (ref out -> ref in, for 10 MHz and PPS). A Master clock of 184 is recommended for LTE. According to previous answers of this post, this configuration is impossible. If the second USRP can be locked on 9.96 MHz, the received frequency will be wrong. In practice (We have just tried), the synchronization fails “Error: RuntimeError: Reference Clock PLL failed to lock to external source”. Any idea of a backup plan ?
Best regards Patrice
