3 - 6 USING THE COMBISCOPE INSTRUMENTS

Functions in a particular subsystem are always controlled by commands that begin with the name of that subsystem. For example, a command that programs the input coupling is INPut:COUPling DC.

All programmable settings can be queried easily. The query form is obtained from the command by simply removing the parameter and adding a question mark. For example, the command to program the input impedance of your oscilloscope is INPut:IMPedance 50. This impedance value can be queried by sending INPut:IMPedance? which returns 50.

3.2.3Instrument setup

This concept allows you to program instrument settings with a single command. Several instrument setups can be saved, either created by remote programming or by front panel control. This concept can also be used to program instrument functions that cannot be directly accessed using individual program instructions. Complete instrument setups can be saved either in the internal memory of the oscilloscope or externally in the remote controller. A part of the instrument setup can also be saved externally.

The oscilloscope is equipped with a number of internal memories in which the complete instrument set up can be saved and from which it can be restored.

Send → *SAV 3 Saves the current set up into memory 3.

Send → *RCL 3 Recalls the instrument set up that was saved in memory 3.

Instead of using an internal oscilloscope memory, the instrument setup can be queried using the SYSTem:SET? query. The result of this query is that the oscilloscope sends a part or the complete setup in a compact block data format. Sending this data back as a parameter with the SYSTem:SET command reprograms the oscilloscope to the same settings.

Example for the complete instrument settings:

Send → SYSTem:SET?	Queries the oscilloscope for the complete
Read ← <block_data>	instrument setup.
	Reads the <block_data> response, which
	contains the requested instrument setup,
Send → SYSTem:SET <block_data>	from the oscilloscope.
	Sends the previously read instrument
	setup back to the oscilloscope in the
	same <block_data> format.
