Fast synchronous ACV/ACDCV example
The following program measures AC voltage using the synchronous method at the
fastest possible rate (approximately 10 readings per second). This program can be
adapted to AC+DC voltage by using the ACDCV command instead of the ACV
command in line 50.
10 OUTPUT 722;"PRESET FAST"!TARM SYN, TRIG AUTO
20 OUTPUT 722;"MFORMAT SINT"!SINT MEMORY FORMAT
30 OUTPUT 722;"MEM FIFO"!ENABLE READING MEMORY

50 OUTPUT 722;"ACV 10,2"!AC VOLTS, 10 V RANGE, 2% RESOLUTION
60 OUTPUT 722;"ACBAND 5E3,8E3"!SIGNAL BETWEEN 5 kHz AND 8 kHz
70 OUTPUT 722;"NRDGS 20, AUTO"!20 READINGS/TRIGGER, AUTO SAMPLE EVENT
80 OUTPUT 722;"TARM SGL"!TRIGGER READINGS
90 END
Fast random ACV/ACDCV example
The following program measures AC voltage using the random method at the
fastest possible rate (approximately 45 readings per second). This program can be
adapted to AC+DC voltage by using the ACDCV command instead of the ACV
command in line 50.
10 OUTPUT 722;"PRESET FAST""!TARM SYN, TRIG AUTO

30 OUTPUT 722;"MEM FIFO"!ENABLE READING MEMORY
40 OUTPUT 722;"SETACV RNDM"!RANDOM AC MEASUREMENT METHOD
50 OUTPUT 722;"ACV 10 6"!AC VOLTS, 10 V RANGE, 6% RESOLUTION
60 OUTPUT 722;"ACBAND 10E3,20E3"!SIGNAL BETWEEN 10 kHz AND 20 kHz
