listparam

List valid parameters for specified circuit object

Syntax

listparam(h)

Description

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

Note

Before calling listparam function, you must use the analyze function to perform a frequency domain analysis for the circuit object.

Examples

List Parameters of Network Object

List the available parameters of analysis of a transmission line.

trl = rfckt.txline;
f = [1e9:1.0e7:3e9];
analyze(trl,f);
listparam(trl)

Input Arguments

h — RF circuit or data object

object handle

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

Several parameters are available for all objects. When you import rfckt.amplifier, rfckt.mixer, or rfdata.data object specifications from a .p2d or .s2d file, 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.

GroupDelay	Group delay
GammaIn, GammaOut	Input and output reflection coefficients
VSWRIn, VSWROut	Input and output voltage standing-wave ratio
