Inheritance diagram for uhd::usrp::cal::iq_dc_cal:

Detailed Description

Class that stores wideband IQ and DC cal data per frequency

The following calibrations use this:

• Wideband (multi-tap) IQ imbalance correction
• DC offset correction

This extends the legacy iq_cal class with support for:

• Multi-tap IQ correction coefficients (vectors instead of single values)
• DC offset correction
• Scaling factor and group delay per frequency
