Find spur-free zones in multiband transmitter or receiver frequency space
zones = getSpurFreeZoneData(hif)
zones = getSpurFreeZoneData(hif) returns the spur-free zones for the network defined by the OpenIF object hif. Each zone is a range of IF center frequencies. An IF signal centered in this range does not generate interference in any transmission or reception bands. The two columns of zones contain the endpoints of each spur-free zone. The first column contains the lower endpoints, and the second column contains the upper endpoints.
The report method displays mixer configurations, intermodulation tables, and spur-free zone information at the command line.
The show method generates an interactive spur graph that shows spurious regions and spur-free zones.
The OpenIF class reference page contains an example that shows how to find the spur-free zones of a multiband receiver with three mixers.
