exportTestbench

Create measurement testbench from RF budget object

Syntax

exportTestbench(rfobj)

sys = exportTestbench(rfobj)

Description

exportTestbench(rfobj) creates an RF Blockset™ model from the RF budget object, and opens a measurement testbench system.

Note

This function requires DSP System Toolbox™.

sys = exportTestbench(rfobj) creates an RF Blockset model, and returns the measurement testbench system.

Measurement Testbench From RF Budget Object

This example uses:

Create an amplifier with a gain of 4 dB.

a = amplifier(Gain=4);

Create a modulator with an OIP3 of 13 dBm.

m = modulator(OIP3=13);

Create an RF element with a gain of 10 dB.

r = rfelement(Gain=10);

Calculate the RF budget of a series of RF elements at an input frequency of 2.1 GHz, an available input power of –30 dBm, and a bandwidth of 10 MHz.

rfobj = rfbudget([a m r],2.1e9,-30,10e6)

rfobj = 
  rfbudget with properties:

               Elements: [1x3 rf.internal.rfbudget.RFElement]
