Returns a structure containing a waveform from an analyzer input port. This command is specific for building analyzers.

 

Supported Product: INTERCONNECT

 

Syntax

Description

signalIn = getmonitorwaveform(port,domain=”time”);

For a scripted element, this command returns a structure containing a waveform from an analyzer input port. Results can be provided in “time” or “frequency’ domains. This command is specific for building analyzers.

 

Implementation Details

Digital signal waveform:

The waveform contains the signal bitrate and two vectors: the time and amplitude values.

#digital signal waveform

bitrate

time=matrix;

value=matrix; 

 

Electrical signal frame:

The waveform contains the signal value and its bandwidth. Frequency or time domain values are available.

#electrical signal frame

bandwidth=struct

bandwidth.frequency

bandwidth.sample_rate

bandwidth.time_window

value=struct

value.amplitude = matrix

value.frequency = matrix

 

Optical signal frame:

The waveform contains the signal channel. The signal channel is a cell which contains the bandwidth, value and mode structs.

#optical signal frame

signal=cell

signal.channel=cell

signal.channel.bandwidth=struct

signal.channel.bandwidth.frequency

signal.channel.bandwidth.sample_rate

signal.channel.bandwidth.time_window

signal.channel.value=struct

signal.channel.value.amplitude

signal.channel.value.frequency

signal.channel.mode=struct

signal.channel.mode.label

signal.channel.mode.orthogonal_identifier

signal.channel.mode.uid

 

 

Example

Implements of a ‘wrapup function of a scripted element with one analyzer digital input port:

signalIn = getmonitorwaveform( "input", "time", 3 );

logmessage(toscript(signalIn,false));

setresult( "waveform", signalIn.time, signalIn.value, "time (s)", "amplitude (a.u.)" );

setresult( "bitrate", signalIn.bitrate, "bitrate (bits/s)" );

 

The digital signal waveform with 32 values for time and amplitude:

SCRIPTED_2: signalIn=struct;

signalIn.bitrate=2.5e+009;

signalIn.time=matrix(32);

signalIn.value=matrix(32);

 

Implements of a ‘wrapup function of a scripted element with one analyzer electrical input port:

signalIn = getmonitorwaveform( "input", "time", 3 );

logmessage( toscript( signalIn, false ) );

setresult( "waveform", signalIn.value.time, signalIn.value.amplitude, "time (s)", "amplitude (a.u.)" );

The electrical signal waveform with 512 values for time and amplitude:

SCRIPTED_2: signalIn=struct;

signalIn.bandwidth=struct;

signalIn.bandwidth.frequency=0;

signalIn.bandwidth.sample_rate=1.6e+011;

signalIn.bandwidth.time_window=3.2e-009;

signalIn.value=struct;

signalIn.value.amplitude=matrix(512);

signalIn.value.frequency=matrix(512);

 

Implements of a ‘wrapup function of a scripted element with one analyzer optical input port:

signalIn = getmonitorwaveform( "input" );

logmessage( toscript( signalIn, false) );

setresult( "waveform", signalIn.signal{1}.channel{1}.value.time, signalIn.signal{1}.channel{1}.value.amplitude, 

"time (s)", "amplitude (a.u.)" );

The optical signal waveform with 512 values for time and amplitude:

SCRIPTED_2: signalIn=struct;

signalIn.signal=cell(1);

signalIn.signal{1}=struct;

signalIn.signal{1}.channel=cell(1);

signalIn.signal{1}.channel{1}=struct;

signalIn.signal{1}.channel{1}.bandwidth=struct;

signalIn.signal{1}.channel{1}.bandwidth.frequency=1.931e+014;

signalIn.signal{1}.channel{1}.bandwidth.sample_rate=1.6e+011;

signalIn.signal{1}.channel{1}.bandwidth.time_window=3.2e-009;

signalIn.signal{1}.channel{1}.value=struct;

signalIn.signal{1}.channel{1}.value.amplitude=matrix(512);

signalIn.signal{1}.channel{1}.value.frequency=matrix(512);

signalIn.signal{1}.mode=struct;

signalIn.signal{1}.mode.label='X';

signalIn.signal{1}.mode.orthogonal_identifier=1;

signalIn.signal{1}.mode.uid='#1';
