Remote command:

Max. Deviation Time
Sets the maximum permissible delay.
The delay
Δ
t
max
depends on the time of emission TOE
timestamp
from timestamp, the
static delay t
static
and the actual time of emission TOE
actual
as follows:
Δ
t
max
= TOE
timestamp
+ t
static
- TOE
actual
If the above sum is greater than the "Max. Deviation Time", the SFN delay (FIFO)
restarts. The transmit signal is reset and transmission is restarted.
