Sampling interval at acquisition, coded as an integer.
In interleaved sampling,
ii = .2 nsec
12 = .4 nsec
13 = .8 nsec
In non-interleaved sampling,
16 = lO nsec
17 = 20 nsec
18 = 40 nsec
19 = 80 nsec
20 = 200 nsec
21 = 400 nsec
.... 34 = 8 msec
35 = 20 msec
36 = 40 msec
In addition to the intervals of the non-interleaved
sampling, SEQNCE mode also uses
40 = i00 nsec
41 = 1 ~sec
42 = 10 psec 43 = i00 psec
44 = I msec
45 = 10 msec
Record type
0 = non-interleaved
3 = interleaved with 25 sweeps at .8 nsec interval
4 = interleaved with 50 sweeps at .4 nsec interval
5 = interleaved with i00 sweeps at .2 nsec interval
-3 = SEQNCE with
8 segments
-4 = SEQNCE with
15 segments
-5 = SEQNCE with
31 segments
-6 = SEQNCE with
62 segments
-7 = SEQNCE with 125 segments
-8 = SEQNCE with 250 segments
Trigger coupling at acquisition
0 = DC
1 = HF REJ
2 = LF REJ
3 = AC
Trigger mode at acquisition
0 = SINGLE
1 = NORM
2 = AUTO
3 = SEQNCE
Trigger source at acquisition
0 = EXT/10
I = EXT
2 = LINE
3 = CHAN 2
4 = CHAN I
Trigger slope at acquisition
0 = negative
I = positive
2 = window
Trigger level at acquisition
The coding depends on the
