It defaults to `0` (automatic selection). This feature is present in GNSS-SDR v0.0.18 and later versions. | Optional | | `sampling_frequency` | Sampling frequency, in samples per second. It defaults to 2 Ms/s. | Optional | | `AGC_enabled` | [`true`, `false`]: If set to `true`, enables Automatic Gain Control. It defaults to `false`. | Optional | +| `iq_balance_mode` | [`0`, `1`, `2`]: Set the RF front-end IQ balance mode: `0` = Off, `1` = Manual, `2` = Automatic. The automatic correction uses an algorithm to adjust for I-Q imbalance. It defaults to `2` (Automatic). This configuration parameter is currently available only in the `next` branch of the upstream repository and will be included in the next stable release. | Optional | +| `dc_offset_mode` | [`0`, `1`, `2`]: Set the RF front-end DC correction mode: `0` = Off, `1` = Manual, `2` = Automatic. The automatic correction subtracts out the long-run average. It defaults to `2` (Automatic). This configuration parameter is currently available only in the `next` branch of the upstream repository and will be included in the next stable release. | Optional | | `samples` | Number of samples to be processed. It defaults to $$ 0 $$, which means infinite samples. | Optional | | `item_type` | [`gr_complex`]: Set the output data type. Only `gr_complex` is allowed in this version, so it is set by default. | Optional | | `osmosdr_args` | Pass arguments to the OsmoSDR driver. Check the [gr-osmosdr wiki](https://osmocom.org/projects/gr-osmosdr/wiki/GrOsmoSDR) for a list of arguments for your specific hardware. | Optional |
