Plot Component Data on Z Smith Chart Using General Amplifier Block
This example shows how to:
Plot component data on a Z Smith Chart using a General Amplifier Block form Equivalaent Baseband library.
Simulate the frequency response of an amplifier using data from the default.s2d S2D file.
Using a RF Blockset Equivalent Baseband example model, you import the data file into a General Amplifier block and validate the amplifier by plotting the S-parameters of the block on a Z Smith Chart. Open the AMP Data File for Amplifier example.
open_system("sparam_amp_rfblks.slx")
Double-click the General Amplifier block to display its parameters. Set Data source parameter to Data file
and Data file parameter to default.s2d
. These values tell the RF Blockset to import data from the file default.s2d
. The block uses this data, along with the other block parameters, in simulation.
Select the Visualization tab and set the General Amplifier block parameters as follows:
In the Plot type list, select
Z Smith chart
.In the Y Parameter1 list, select
S22
.
Click Plot. This action creates a Z Smith Chart of the S22 parameters using the frequency data from the default.s2d file.
