Triggered Sequence
Advance
5 specifies that 5 binary bytes will follow
and the <0000230145h>:
74565 is 00012345h rearranged to be 234501
Four zeros (0000) for segment 1 (segment 0)
Putting these together gives 0000234501.
Triggered Sequence Advance is a special case sequenced mode.
In Triggered Sequence Advance mode, the Model 3151/3151A idles
between steps until a valid trigger signal is sensed. The trigger
source can be selected from a number of options:
•
An external trigger signal applied to the front panel TRIG IN
connector
•
An internal trigger generator whose period is programmable
•
VXIbus TTLTRG<n> triggers
•
soft triggers.
A sequence operating in Continuous mode can be seen in Figure 3-
6. Figure 3-8 shows an example of the same sequence in Triggered
Sequence Advance mode.
