19.2 | 40 | == Измерение полной задержки трансивера ERMAK-TT + EAX (USB) == |
| 41 | |||
| |
19.9 | 42 | Измерения проводились на Windows 11 PC Host + VAC от Евгения Музыченко. Так же можно использовать оригинальные VAC от ERMAK. Они дают немного меньшую задержку за счет оптитмизации буферов. |
| |
19.2 | 43 | |
| |
19.9 | 44 | **Важный момент** - оригинальные ERMAK VAC подписаны self signed сертификатом. Поэтому, на PC host необходимо отключить проверку подписи драйверов. |
