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.

20 OUTPUT 722;"MFORMAT SINT" !SINT MEMORY FORMAT
30 OUTPUT 722;"MEM FIFO" !ENABLE READING MEMORY
40 OUTPUT 722;"SETACV SYNC" !SYNCHRONOUS AC MEASUREMENT METHOD
50 OUTPUT 722;"ACV 10,2" !AC VOLTS, 10V RANGE, 2% RESOLUTION
60 OUTPUT 722;"ACBAND 5E3,8E3" !SIGNAL BETWEEN 5kHz AND 8kHz

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.

Fast Analog ACV/ ACDCV
Example
The following program measures AC voltage using the analog method at a
fast rate. This program uses the default delay time. You can achieve faster
reading rates by specifying a shorter delay time; the resulting settling time,
however, may not produce accurate measurements. You can also achieve
unspecified faster reading rates by specifying less integration time in line 60.
This program can be adapted to AC+DC voltage by using the ACDCV
command instead of the ACV command in line 50.
