ITFRONTENDMODE

Configure the front end mode settings

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7

Use this command to configure the front end mode for the L1, L2 and L5 RF paths to use the default third-order CIC mode or HDR (High Dynamic Range) mode. The HDR mode is used in an interference environment to obtain best interference rejection in general. However, the power consumption will increase in this mode.

To configure the front end mode settings for the secondary antenna of dual antenna receivers (OEM7720, PwrPak7D, PwrPak7D-E1, PwrPak7D-E2 and CPT7), use the ITFRONTENDMODE_1 command.

This command is available only on some software models. Contact your NovAtel Sales representative (novatel.com/contactus/sales-offices) to obtain interference mitigation functionality.
