drplGetSpectrum

drplGetSpectrum(
t_wirelessProbe
)
=> o_waveform / nil

Description

Creates a waveform object that represents the spectrum of the signal to which the specified wireless probe is connected. The x- and y-axis vectors of the waveform are frequency and dBv/Hz, respectively.

You must have run a wireless envelope simulation before using this function.

Arguments

t_wirelessProbe

Name of the wireless probe which is connected the signal whose spectrum you want to plot.

Value Returned

o_waveform	A waveform object, representing the spectrum of the signal to which the specified wireless probe is connected.
nil	Cannot create the waveform object because of an error.

Examples

The following example shows how to plot spectrum of the signals to which the wireless probes, WPRB1 and WPRB2 are connected.

openResults("/home/user/envlpsim/WirelessLib/wireless_LTE_W_Modulator_and_DAC_12_bit/maestro/results/maestro/ExplorerRun.0/psf/Wireless/psf")

;Opens the simulation results of wireless envelope analysis stored in the specified directory.

results()

;Lists the results available in the currently open results directory.

selectResult('envlp_fd)

;Selects the results result 'envlp_fd'.

w1=drplGetSpectrum("WPRB1")

;Creates a waveform object that represents the spectrum of the net (signal) to which the wireless probe WPRB1 is connected.

w2=drplGetSpectrum("WPRB2")

;Creates a waveform object that represents the spectrum of the net (signal) to which the wireless probe WPRB2 is connected.

awvCreatePlotWindow()

;Creates a Waveform window.
