analyze

Analyze RFCKT object in frequency domain

Syntax

analyze(rfcktobject,frequency)

analyze(rfcktobject,frequency,zl,zs,zo,aperture)

analyze(rfcktobject,frequency,condition,value)

Description

analyze(rfcktobject,frequency) calculates the following rfckt data at the specified frequency values:

• Circuit network parameters

• Noise figure

• Output third-order intercept point

• Power data

• Phase noise

• Voltage standing-wave ratio

• Power gain

• Group delay

• Reflection coefficients

• Stability data

• Transfer function

analyze(rfcktobject,frequency,zl,zs,zo,aperture) calculates the circuit data specified frequency values with optional arguments such as load impedance, source impedance, reference impedance and aperture.

analyze(rfcktobject,frequency,condition,value) calculates the circuit data at the specified frequency values and operating conditions for the circuitdata object

Note

When you specify condition/value pairs, the analyze method changes the object's values to match your specification.

Examples

Analyze Network Object
