+Интерпретация: таблицы являются измерениями; никакая коррекция DC, новый порог, эквалайзер или новая фаза автоматически не применялись.
+Классификация: B. Ошибки 000/001 отсутствуют в полном цифровом TX-RRC -> RX-RRC тракте и появляются только в реальном IQ. Промежуточная зависимость амплитуды после одного TX-RRC полностью компенсируется согласованным RX-RRC в идеальном канале.
+Наиболее вероятный механизм: совместное действие комплексного смещения середины кластеров и длинной памяти/ISI аппаратного тракта. FIR+DC-модель, обученная на первой половине и проверенная на второй, воспроизводит часть ошибок 000 без шума, но не весь измеренный BER; место внутри Pluto TX, кабеля/аттенюатора или RTL RX по этим данным не разделяется.
+AC coupling отдельно не доказан: падение уровня длинных серий устойчиво, но оценённая низкочастотная АЧХ различается между двумя S и не образует однозначной монотонной высокочастотной характеристики.
+Следующий диагностический шаг, пока не выполненный: сравнительный приём того же S другим приёмником либо loopback-разделение TX/RX с заранее фиксированными параметрами; после локализации отдельно проверить DC/АЧХ.

+Lab043: единственный сравнительный S с HackRF

+HackRF: 000000000000000097c063dc323b97d3, firmware 2024.02.1 (API:1.08), libhackrf 2024.02.1 (0.9).
+RX: 435 МГц, запрос 2 400 000 отсчётов/с, RF amp OFF, LNA 0 дБ, VGA 0 дБ.
+Pluto+: фактически 435000000 Гц, 2399998 отсчётов/с, gain -30.0 дБ, RF bandwidth 200000 Гц.
+
+Программная сборка: 32 рабочих callback после одного заранее отброшенного разогревочного; индексы последовательны, дубликатов полных блоков 0, пропусков очереди 0.
+Средняя callback-скорость: 2399817.412 отсчётов/с.
+USB-потери аппаратно не доказаны и не опровергнуты: внутреннего счётчика API нет.
+
+Два тона найдены неизменным спектральным порогом 10 дБ: нижний +15.582 дБ, верхний +15.510 дБ.
+Максимальный рост полной мощности: только 0.871 дБ, поэтому исходный широкополосный локатор не сработал.
+Предварительная оценка CFO: +462.074 Гц (+1.062239 ppm).
+Предварительная оценка SRO: +273.149 ppm.
+Эти оценки нельзя считать итоговыми: RMSE фазовой модели 19.909 рад и в калибровке подтверждено 3 фазовых разрыва из 3 проверенных границ; максимум 1.962 рад при пределе 0,25 рад.
+
+Маркер: N/A.
+BER (доля ошибочных битов): N/A.
+BER по четвертям: N/A.
+EVM (величина вектора ошибки): N/A.
+Тройки 000–111, серии и кластеры: N/A, чтобы не выдавать недостоверный захват за измерение.
+
+Сравнение с RTL-SDR невозможно: два RTL-SDR S валидны, а HackRF S не прошёл контроль непрерывности. Главный текущий подозреваемый не 000/001-механизм, а достоверность приёма HackRF на минимальном усилении и/или непрерывность USB/драйвера. Усиления и пороги не менялись, повторный TX не выполнялся.
+
+Следующий шаг, пока не выполненный: отдельно доказать непрерывность HackRF RX и достаточную фазовую точность на 2,4 Мвыб/с без изменения протокола; только затем отдельно решить, разрешать ли новый S или изменение усиления.
