The same command sequence using the *OPC command for synchronizaĆ
tion with serial polling looks like this:
/* Set up singleĆsequence acquisition */
SELECT:CH1 ON
ACQUIRE:MODE SAMPLE
ACQUIRE:STOPAFTER SEQUENCE
/* Enable the status registers */
DESE 1
*ESE 1
*SRE 0
/* Acquire waveform data */
ACQUIRE:STATE ON
/* Set up the measurement parameters */
MEASUREMENT:IMMED:TYPE AMPLITUDE
MEASUREMENT:IMMED:SOURCE CH1
/* Wait until the acquisition is complete before taking the measurement */
*OPC
While serial poll = 0, keep looping
/* Take amplitude measurement on acquired data */
MEASUREMENT:IMMED:VALUE?
This technique requires less bus traffic than did looping on BUSY?.
