d sequence using the *WAI command for synchronization
looks like this:
/* Set up conditional ac quisition */
ACQUIRE:STATE OFF
SELECT:CH1 ON
ACQUIRE:MODE SAMPLE
ACQUIRE:STOPAFTER SEQUENCE
/* Acqu ire waveform data */
ACQUIRE:STATE ON
/* Set up the measurement parameters */
MEASUREMENT:IMMED:TYPE AMPLITUDE
MEASUREMENT:IMMED:SOURCE CH1
/* Wait until the acquis ition is complete before taking
the mea surement */
*WAI
/* Take amplitude measurement */
MEASUREMENT:IMMED:VALUE?
The controller can continue to write commands to the input buffer of the
oscilloscope, but the commands will not be processed by the oscilloscope until
all in-process OPC operations are complete. If the input buffer becomes full,
the controller will be unable to write commands to the buffer. This can cause a
time-out.
Using the BUSY Query
The BUSY? query allows you to find out whether the oscilloscope is busy
processing a command that generates OPC.
The same command sequence, using the BUSY? query for synchronization, looks
like this:
/* Set up conditional ac quisition */
ACQUIRE:STATE OFF
SELECT:CH1 ON
ACQUIRE:MODE SAMPLE
ACQUIRE:STOPAFTER SEQUENCE
/* Acqu ire waveform data */
ACQUIRE:STATE ON
/* Set up the measurement parameters */
MEASUREMENT:IMMED:TYPE AMPLITUDE
MEASUREMENT:IMMED:SOURCE CH1
/* Wait until the acquis ition is complete before taking
the mea surement */
While B USY keep looping
/* Take amplitude measurement */
MEASUREMENT:IMMED:VALUE?
This sequence lets you create your own wait loop rather than using the *WAI
command. The BUSY? query helps you avoid time-outs caused by writing too
