Acquiring data by communication commands ______________________
Transferring storage data (measurement values)
Use :MEMory:VDTA? A.
Transferring storage data in binary format
Use :MEMory:BDATA? A.
Procedure
1
:MEMory:MAXPoint?
The number of data samples stored in the memory of the instrument is acquired.
Check that storage data exists.
2.
:MEMory:POINt CH$,A
The output point of the storage data is specified.
(If you want to acquire the data from the beginning, change the value of A to 0.)
3.
:MEMory:VDATA? A
Just the number of data samples of the storage data (measurement values) specified with A is transferred
from the instrument to the computer. The output point is also incremented by the number of data samples.
• From 1 to 80 values can be acquired at one time with the VDATA command. If
you want to acquire more values than that, send the command in step
3
repeatedly.
• The maximum number of data samples that can be acquired is the value
acquired with the MAXPoint command.
