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.

`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.

Parameter	Description

`GroupDelay`	Group delay
`GammaIn`, `GammaOut`	Input and output reflection coefficients
`VSWRIn`, `VSWROut`	Input and output voltage standing-wave ratio
`IIP3`, `OIP3` (Amplifier and mixer objects only)	Third-order intercept point
`NF`	Noise figure
`TF1`	Ratio of the load voltage to the output voltage of the source when the input port is conjugate matched
`TF2`	Ratio of load voltage to the source voltage
`Gt` `Ga` `Gp` `Gmag` `Gmsg`	Transducer power gain Available power gain Operating power gain Maximum available power gain Maximum stable gain
`GammaMS`, `GammaML`	Source and load reflection coefficients for simultaneous conjugate match
`K`, `Mu`, `MuPrime`	Stability factor
