USING THE COMBISCOPE INSTRUMENTS 3 - 3
3.2 Fundamental Programming Concepts
The remote operation of your CombiScope instrument can be accessed using
different programming concepts. The concept to be chosen depends upon the
application of the instrument in the remote programming environment. Each of the
four concepts has it own benefits and trade-offs.
1) Using measurement instructions
Advantage: Easy to program. No instrument knowledge required to make
measurements. So, you can start programming quickly and get
measurement results rightaway.
Trade-off: A measurement takes some time to complete, because the
instrument automatically searches for optimal settings.
Example:
MEASure:FREQuency?
Measures the frequency of the
signal at channel 1.
2) Single function programming using the instrument model
Advantage: Allows you to program individual functions separately through
single commands. The instrument model gives the relation
between the commands and the functions of the CombiScope
instrument.
Trade-off: Requires understanding of the remote operation of the instrument
functions.
Example:
TRACe? CH1
Returns the acquisition trace of
the signal at channel 1.
3) Programming the complete instrument setup
Advantage: Simple to program. No worry about individual settings. This
method can also be used to save and recall settings, which are
not individually programmable.
Trade-off: Processes complete instrument setups. Individual settings
must be set or programmed separately.
Example:
*
SAV 3
Saves actual instrument settings
to internal memory 3.
*
RCL 3
Recalls instrument settings from
internal memory 3.
4) Programming through front panel simulation
Advantage: Gives the possibility to program settings for which no remote
commands are available, i.e., to match a front panel setup.
