adi.AD9081.Tx

The adi.AD9081.Tx System object is a signal sink that can tranmsit
complex data from the AD9081.

tx = adi.AD9081.Tx;
tx = adi.AD9081.Tx('uri','ip:ip:192.168.2.1');

AD9081 Datasheet

Creation

The class can be instantiated in the following way with and without property name value pairs.

dev = adi.AD9081.Tx
dev = adi.AD9081.Tx(Name, Value)

Properties

Unless otherwise indicated, properties are non-tunable, which means you cannot change their values after calling the object. Objects lock when you call them, and the release function unlocks them.

If a property is tunable, you can change its value at any time.

For more information on changing property values, see System Design in MATLAB Using System Objects.

ChannelNCOFrequencies +

Frequency of NCO in fine decimators in transmit path. Property must be a [1,N] vector where each value is the frequency of an NCO in hertz.

MainNCOFrequencies +

Frequency of NCO in fine decimators in transmit path. Property must be a [1,N] vector where each value is the frequency of an NCO in hertz.

ChannelNCOPhases +

Frequency of NCO in fine decimators in transmit path. Property must be a [1,N] vector where each value is the frequency of an NCO in hertz.

MainNCOPhases +

Frequency of NCO in fine decimators in transmit path. Property must be a [1,N] vector where each value is the frequency of an NCO in hertz.

ChannelNCOGainScales +

Frequency of NCO in fine decimators in transmit path. Property must be a [1,N] vector where each value is the frequency of an NCO in hertz.

NCOEnables +

Vector of logicals which enabled individual NCOs in channel interpolators

SamplesPerFrame +

Number of samples per frame, specified as an even positive integer from 2 to 16,777,216. Using values less than 3660 can yield poor performance.Help for adi.AD9081.Tx/SamplesPerFrame is inherited from superclass ADI.AD9081.BASE

EnabledChannels +

Indexs of channels to be enabled. Input should be a [1xN] vector with the indexes of channels to be enabled. Order is irrelevant

uri +

Hostname or IP address of remote libIIO deviceHelp for adi.AD9081.Tx/uri is inherited from superclass MATLABSHARED.LIBIIO.BASE

DataSource +

Data source, specified as one of the following: 'DMA' — Specify the host as the source of the data. 'DDS' — Specify the DDS on the radio hardware as the source of the data. In this case, each channel has two additive tones.Help for adi.AD9081.Tx/DataSource is inherited from superclass ADI.COMMON.DDS

DDSFrequencies +

Frequencies values in Hz of the DDS tone generators. For complex data devices the input is a [2xN] matrix where N is the available channels on the board. For complex data devices this is at most max(EnabledChannels)*2. For non-complex data devices this is at most max(EnabledChannels). If N < this upper limit, other DDSs are not set.Help for adi.AD9081.Tx/DDSFrequencies is inherited from superclass ADI.COMMON.DDS

DDSScales +

Scale of DDS tones in range [0,1]. For complex data devices the input is a [2xN] matrix where N is the available channels on the board. For complex data devices this is at most max(EnabledChannels)*2. For non-complex data devices this is at most max(EnabledChannels). If N < this upper limit, other DDSs are not set.Help for adi.AD9081.Tx/DDSScales is inherited from superclass ADI.COMMON.DDS

DDSPhases +

Phases of DDS tones in range [0,360000]. For complex data devices the input is a [2xN] matrix where N is the available channels on the board. For complex data devices this is at most max(EnabledChannels)*2. For non-complex data devices this is at most max(EnabledChannels). If N < this upper limit, other DDSs are not set.Help for adi.AD9081.Tx/DDSPhases is inherited from superclass ADI.COMMON.DDS

EnableCyclicBuffers +

Enable Cyclic Buffers, configures transmit buffers to be cyclic, which makes them continuously repeatHelp for adi.AD9081.Tx/EnableCyclicBuffers is inherited from superclass ADI.COMMON.DDS

Example Usage

%% Configure device
