This is the template for the [[:Category:Block_Docs|"Page-per-block Docs"]].  This first section should describe what the block does and how to use it, using however many paragraphs necessary.  Note that the title of the wiki page should match the block's name in GRC, i.e. the one defined in the block's .grc file.  Look at the [[FFT]] Block for a good example.


As this is a basic template, it's also in the [[:Category:Stub_Docs|"Stub Docs category"]]. Please improve it.

Hierarchical block that combines Phase Noise Generator, IQ Imbalance Generator, Second Order Distortion, Third Order Distortion, IQ offset and frequency offset

Here is the flowgraph corresponding to the implementation (without the parameters)

HW-impairements-hier-block.png

Parameters

(R): Run-time adjustable

Phase Noise Mag. (R)
Magnitude given to the Phase Noise Generator. (Alpha is set to 0.01)
IQ Mag. Imbalance (R)
Magnitude parameter for the IQ Imbalance Generator.
IQ Phase. Imbalance (R)
Phase parameter for the IQ Imbalance Generator. (The mode is set to Receiver)
Quadrature Offset (R)
Offset added to the Q channel.
Inphase Offset (R)
Offset added to the I channel.
Frequency Offset (R)
Frequency offset to add.
Second Order Distortion (R)
Parameter given to the Second Order Distortion block.
Third Order Distortion (R)
Parameter given to the Third Order Distortion block.


Example Flowgraph

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
