Description

example

listparam(h)lists the valid parameters for the specified circuit objecth.

Note

Before callinglistparamfunction, you must use theanalyzefunction to perform a frequency domain analysis for the circuit object.

Input Arguments

collapse all

RF circuit or data object, specified as an object handle.

Several parameters are available for all objects. When you importrfckt.amplifier,rfckt.mixer, orrfdata.dataobject specifications from a.p2dor.s2dfile, the list of valid parameters also includes any operating conditions from the file that have numeric values, such as bias.

This table describes the most commonly available parameters.
