When the Controller sends a correct “S” or “F” command the instrument will echo back
the identical command string if a GPIB read command is sent after the command string.
If an error occurs when the command is sent the instrument will send an ASCII code 15h
after the read command is sent.
The following functions will read data from the instrument when executed. For every
command written, a corresponding read command of the appropriate byte length (shown
below) must be executed to retrieve the data from the instrument.
