Summarize mixer configurations and spur-free-zone information for a multiband transmitter or receiver




report(hif) displays a summary at the command line of the information contained in the OpenIF object hif. The summary contains:

  • The IF location.

  • The properties of each mixer, including the RF center frequencies, bandwidths, mixing types, and intermodulation tables.

  • The spur-free zones.

Each spur-free 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.

Input Arguments

collapse all

Intermediate frequency planning object, specified as OpenIF object.


For an IF-planning example using an OpenIF object, see the examples section of the OpenIF class reference page.


  • The getSpurFreeZoneData returns the endpoints of the spur-free zones in a matrix.

  • The show method generates an interactive spur graph that shows spurious regions and spur-free zones.

Introduced in R2011b
