GPIB-410 User Manual

Selecting 

PULSE

 causes a pulse to be sent each time the pattern occurs

on the bus.  The number of pulses output per pattern is equal to the
pattern repetition factor.

Trigger Action

Use this field to specify the action to be taken once the trigger pattern
sequence has been satisfied.  There are three options.

•

TRIGGER with position:

•

GO TO 

label

•

STOP and sound speaker

Each of the above options is described in the following paragraphs.

•

TRIGGER WITH POSITION:

This option causes the GPIB-410 to trigger a capture operation.  Use
the adjacent sub-field to specify the relative position of the trigger
point 

T

 among the captured data.  Any one of five positions can be

selected.

TRIGGER with position:

T

If the 

T

 is placed in the left-most position, capturing does not begin

until the Trigger Spec is satisfied.  Placing the 

T

 in any other

position causes background capturing to begin as soon as the trigger
is armed.  In either case, when the trigger occurs the next capture
entry is marked as the trigger point and any previous entries in the
buffer are realigned so as to position the trigger point as requested.
Foreground capturing then proceeds according to the options
selected on the Capture Settings screen.

•

GO TO 

label

This option causes the GPIB-410 to repeat the pattern sequence
from the pattern specified by label each time the end of the
sequence is reached.  This looping action continues until you disarm
the trigger by typing <Alt-T>.  Any visible pattern label from 

1

 to 

9

can be selected as the loop target.

This option is useful when you wish to repeat indefinitely a pattern
sequence producing one or more pulses on the TRG output port of
the GPIB-410.
