time. However, non-sequential commands can also be a source of annoying errors.
Always use the *OPC query or *WAI command with the non-sequential commands
to ensure that your programs execute properly.
For example, suppose that you wanted to set the elevation correction value and then
send an :INIT:IMM command. The following programming fragment results in an
error
–213 “Init ignored” . This occurs because the :ELEVation command causes
the recalculation of the data which is like sending the :INIT:IMM command. When
the actual :INIT:IMM is sent, the error occurs because the command is already in
progress.
OUTPUT 720;”:INIT:IMM”
OUTPUT 720;”:SENSe:CORRection:ELEVation 1000”
OUTPUT 720;”:INIT:IMM”
Use an *OPC? query to ensure that the :
ELEVation
command has completed as
shown in the following lines:
OUTPUT 720;”:INIT:IMM”
OUTPUT 720;”:SENSe:CORRection:ELEVation 1000”
OUTPUT 720;”*OPC?”
ENTER 720;Response$
OUTPUT 720;”:INIT:IMM”
Or, the *WAI command could be used:
OUTPUT 720;”:INIT:IMM”
OUTPUT 720;”:SENSe:CORRection:ELEVation 1000”
OUTPUT 720;”*WAI?”
OUTPUT 720;”:INIT:IMM”
