Itinterferencedetect - Novatel OEM6 Integration Manual

Chapter 2 New for OEM7 – Firmware

2.2.16 ITINTERFERENCEDETECT

Enable and configure interference detection on receiver
Platform: OEM729, OEM719, OEM7700
This command is used to configure interference detection on the receiver. Detection can be
enabled or disabled and certain parameters around the detection algorithm can be configured. If
the RF path parameter is set to DEFAULT, the interference detection algorithm will periodically
cycle through each RF path configured on the receiver (i.e. L1, L2, L5). The FFT windowing used
is Hanning.
Decreasing the update period or increasing the FFT size will impact receiver idle time.
The idle time should be monitored to prevent adverse effects on receiver performance.
