General Programming Aspects

Programming Recommendations

When you have found the correct setting, then use this to create the program. In the program it is recommended to send the command for enabling outputs (for example, :OUTPut ON) as the last command. With this procedure it is possible to switch off the error check system (:SYSTem:CHECk OFF) to increase programming speed.

The error check is enabled again by sending *RST.

*RST		# set default settings
:DISP	OFF	# switch off display update
:SYST:CHEC OFF		# switch off error check
...		# other commands to set modes
...		# and parameters
:OUTP	ON	# enable the output

•Selftest of the instrument can be invoked by the common command

*TST

•If it is important to know whether the last command is completed, then send the common command

*OPC?
