IQ Dump

The IQ Dump test is the base test for retrieving data off the SDR itself (in the form of IQ data). Although the primary purpose of this test is to be run by other tests, it can also be user run if a sampling of IQ data is needed.

Test capabilities

• Applying a stimulus

It makes little sense for this test to verify the power of an applied stimulus since no power calculations are being done. For this, please use Power Measurement which will also retrieve the IQ data if needed.

Data Saving and Plotting

• logging_save_iq_data: Setting this to True will generate an output CSV file which contains the IQ data taken from the SDR (this does not contain the conditioning samples taken before the real data)

Note: Plotting is currently not implemented for this test

Possible equipment

• SDR
• Signal Generator
• Programmable Attenuator

Profile Categories

• Test Parameters
  • test_type = 'iq_dump
  • test_number_of_samples = [USER_SET] Note: this is the only test using this profile value for the number of samples. It is required for this test and ignored in all others.
• Frequency Parameters
• Power Parameters
  • power_verification can be set to True, but it will be ignored
• Logging Parameters
