port.
2)
Use the DIGITAL:SYNCHRONOUS:DATA command
to load the data bytes which will be clocked out.
D) For each Synchronous Input Port:
1)
Use the DIGITAL:STATE command to disable the
port.
2) Use the DIGITAL:SYNCHRONOUS:POINTS
command to define the number of data points that
will be acquired and stored for the port.
E)
Arm the 1260-114 module by using the
DIGITAL:SYNCHRONOUS:STATE command.
F) Generate pulses on the CLKIN line of the 1260-114 module.
The 1260-114 module will disarm itself when the number of
pulses is equal to, or greater than, the maximum of:
1)
The greatest number of data points downloaded to
any synchronous output port on the module (equals
the value returned by DIGITAL:SYNC:INDEX?).
2)
The greatest number of data points defined for any
synchronous input port on the module ( equals the
value returned by DIGITAL:SYNC:POINTS?).
All data operations are complete when the module disarms itself.
The DIGITAL:SYNCHRONOUS:STATE? query may be used to
determine if the specified module(s) are armed or disarmed.
