Output Data Per Point
The GPIB command OUTPDATP returns the value of the selected point using FORM4
(ASCII). The point is selected using the SELPT command. This returns the last point if the
selected point is out of range. Otherwise, it uses the same format as that used by the
marker value command. These formats are as follows:
The commands in the following example are sent while using the format command LOGM.
Example:
Sending SELPT5 and OUTPDATP may return the following:
−3.513410E+00, 0.00915E+15 (Note that the second number is insignificant.)
