Model 6517A Getting Started Manual
Remote Operation
3-21
Continuous triggering #1
The following example program sets up the Model 6517A to take readings as fast as it can
once it receives an external trigger. The actual reading rate will depend upon other factors,
such as A/D integration time, autorange on/off, etc.
'Example program to demonstrate continuous triggering
'For QuickBASIC 4.5 and KPC-488.2/CEC interface card
'Edit the following line to where the QuickBASIC
'libraries are on your computer
'$INCLUDE: 'c:\qb45\ieeeqb.bi'
'Initialize the interface as address 21
CALL initialize(21, 0)
'Reset controls in INIT, ARM;LAY1, ARM:LAY2, and TRIG subsystems
'and put trigger model in IDLE state
CALL SEND(27, "*rst", status%)
'*RST sets TRIG:SOUR to IMM
CALL SEND(27, "arm:lay2:sour ext", status%)
CALL SEND(27, "trig:coun inf", status%)
'start everything
CALL SEND(27, "init", status%)
After the Model 6517A receives the
INITiate
command, it stops in
ARM:LAYer2
of
the trigger model, waiting for a pulse on the external trigger jack. After the external trigger
signal occurs, the Model 6517A moves to the
TRIGger
layer. Since
TRIGger:SOURce
is set to
IMMediate
, a reading is triggered immediately, with a subsequent reading trig-
gered as soon as the previous one is finished.
