adi.ADRV9002.Rx#

The adi.ADRV9002.Rx System object is a signal source that can receive
complex data from the ADRV9002.

rx = adi.ADRV9002.Rx;
rx = adi.ADRV9002.Rx('uri','ip:192.168.2.1');

ADRV9002 Datasheet
Creation

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

dev = adi.ADRV9002.Rx
dev = adi.ADRV9002.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.

InterfaceGainChannel0

This is the final gain in the digital path with possible values: -36:6:18 This gain should be selected based on primary signal bandwidth. For narrowband applications higher levels of interface gain should be used (0:18) to allow signal level and analog noise to dominate. For wideband applications this gain should be reduced or disabled since quantization noise is minimal. Note that the available options for this gain depend on the profile loaded and picking an option outside of those options generates an error.

InterfaceGainChannel1

This is the final gain in the digital path with possible values: -36:6:18 This gain should be selected based on primary signal bandwidth. For narrowband applications higher levels of interface gain should be used (0:18) to allow signal level and analog noise to dominate. For wideband applications this gain should be reduced or disabled since quantization noise is minimal. Note that the available options for this gain depend on the profile loaded and picking an option outside of those options generates an error.

DigitalGainControlModeChannel0

The digital gain control has two major purposes, one for gain correction which is to correct the small step size inaccuracy in analog front-end attenuation and the other for gain compensation which is to compensate for the entire analog front-end attenuation. The digital gain block is controlled by the Rx gain table. Different digital gain will be applied when configured in gain correction or gain compensation mode. The Rx gain table has a unique front-end attenuator setting, with a corresponding amount of digital gain, programmed at each index of the table. In the end of the Rx data path, the interface gain could be further applied by using a “Slicer” block for 2 major purposes. One is to avoid digital saturation in gain compensation mode. The other one is to ensure the overall SNR is limited only by analog noise and unaffected by quantization noise. Gain correction should be used when external components (LNA or DSA) does not need to be controlled. Compensation should be used for external LNA or DSA control. Gain control is specified as one of the following: ‘automatic’ - Automatically adjust interface gain ‘spi’ - Manually adjust interface gain
