Format of Trigger Time(s)
The trigger time is the time interval between the occurrence of the
trigger and the measurement of the next data sample. This time is
always expressed in units of 2,*(-14) of the nominal sampling interval,
and spans integer values from 0 to 2"*(14)-1 = 16383. The transmission
format is a 16-bit integer, with the most significant byte sent before
the least significant byte.
In single-shot acquisition (INTERLEAVED OFF), there is a single time
value.
In SEQNCE acquisition, there are as many trigger times as there are
sweeps. The trigger times are transmitted in the order i to N, where N
is the number of sweeps.
In
INTERLEAVED acquisition, there are as many trigger times as there
are
interleaved sweeps making up the acquired trace:
-
At 2 ~sec/div, there are 25 sweeps at a nominal interval of 800 psec.
- At I ~sec/div, there are 50 sweeps at a nominal interval of 400 psec.
- At 500 nsec/div and below, there are i00 sweeps at a nominal interval
of 200 psec.
The times are transmitted in the order 0 to N-I, where N is the number
of sweeps. Note that time i (0 <= i < N) corresponds to the data points
at address i, N + i, 2N + i, 3N + i, etc., i.e. to all data points of a
single sweep.
