ACQUIRE:MODE SAMPLE
ACQUIRE:STOPAFTER SEQUENCE
/* Acquire waveform data */
ACQUIRE:STATE ON
/* Set up the measurement parameters */

/* Wait until the acquisition is complete before taking
the measurement*/

/* 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 has an extended processing time such as
single-sequence acquisition.
