adi.AD9361.Rx

The adi.AD9361.Rx System object is a signal source that can receive
complex data from the AD9361.

rx = adi.AD9361.Rx;
rx = adi.AD9361.Rx('uri','ip:192.168.2.1');

AD9361 Datasheet

Creation

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

dev = adi.AD9361.Rx
dev = adi.AD9361.Rx(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.

CenterFrequency

RF center frequency, specified in Hz as a scalar. The default is 2.4e9. This property is tunable.

SamplingRate

Baseband sampling rate in Hz, specified as a scalar from 65105 to 61.44e6 samples per second.

RFBandwidth

RF Bandwidth of front-end analog filter in Hz, specified as a scalar from 200 kHz to 56 MHz.

GainControlModeChannel0

specified as one of the following: ‘slow_attack’ — For signals with slowly changing power levels ‘fast_attack’ — For signals with rapidly changing power levels ‘manual’ — For setting the gain manually with the Gain property ‘hybrid’ — For configuring hybrid AGC mode

GainChannel0

Channel 0 gain, specified as a scalar from -3 dB to 71 dB. The acceptable minimum and maximum gain setting depends on the center frequency.

GainControlModeChannel1

specified as one of the following: ‘slow_attack’ — For signals with slowly changing power levels ‘fast_attack’ — For signals with rapidly changing power levels ‘manual’ — For setting the gain manually with the Gain property ‘hybrid’ — For configuring hybrid AGC mode

GainChannel1

Channel 1 gain, specified as a scalar from -3 dB to 71 dB. The acceptable minimum and maximum gain setting depends on the center frequency.

LoopbackMode

Option to set digital loopback mode, specified as 0, 1 or 2. Allows either to digitally loopback TX data into the RX path or vice versa. Value | Mode ————————— 0 | Disable 1 | Digital TX -> Digital RX 2 | RF RX -> RF TX

EnableQuadratureTracking

Option to enable quadrature tracking, specified as true or false. When this property is true, IQ imbalance compensation is applied to the input signal.

EnableRFDCTracking

Option to enable RF DC tracking, specified as true or false. When this property is true, an RF DC blocking filter is applied to the input signal.

EnableBasebandDCTracking

Option to enable baseband DC tracking, specified as true or false. When this property is true, a baseband DC blocking filter is applied to the input signal.

RFPortSelect

‘A_BALANCED’ ‘B_BALANCED’ ‘C_BALANCED’ ‘A_N’ ‘A_P’ ‘B_N’ ‘B_P’ ‘C_N’ ‘C_P’ ‘TX_MONITOR1’ ‘TX_MONITOR2’ ‘TX_MONITOR1_2’

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.

EnableCustomFilter

Enable use of custom filter file to set SamplingRate, RFBandwidth, and FIR in datapaths

CustomFilterFileName

Path to custom filter file created from filter wizard

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.AD9361.Rx/uri is inherited from superclass MATLABSHARED.LIBIIO.BASE

enIO

If true, connects to libIIO device during simulationHelp for adi.AD9361.Rx/enIO is inherited from superclass MATLABSHARED.LIBIIO.BASE

Example Usage

%% Rx set up
rx = adi.AD9361.Rx('uri','ip:analog.local');

rx.CenterFrequency = 1e9;

rx.EnabledChannels = 1;
%% Run
for k=1:10
    valid = false;
    while ~valid
        [out, valid] = rx();
    end
