14.2 Backward Compatibility with Other Rohde & Schwarz
Signal Generators
To allow you to use your existing scripts, the R&S SMW accepts also a defined subset
of SCPI parameter values of other Rohde & Schwarz signal generators, like the
R&S SMU. The R&S SMW accepts these values and maps them automatically to the
corresponding newly introduced parameters.
Handling of parameters provided for backward compatibility with other
Rohde & Schwarz signal generators
The parameter values provided for backwards compatibility are "setting only" values;
the query commands return the corresponding new value.
Example:
:SOURce1:BB:ARBitrary:TRIGger:SOURce EXTernal
The backwards compatibility parameter value EXTernal is accepted
:SOURce1:BB:ARBitrary:TRIGger:SOURce?
Response: EGT1
The query returns the correct new value
14.3 SCPI Command Aliases for Advanced Mode with Mul-
tiple Entities
When working in Advanced mode, the R&S SMW can generate the signal of several
entities. An entity is a self-contained independent system, consisting of a baseband
source, a fading simulator, a noise generator (AWGN), and an RF part.
Additional baseband, fading, and AWGN SCPI commands are provided to allow con-
sistent addressing of the entities in remote control. All these commands start with the
mnemonic (keyword) ENTity.
The additional SCPI commands are not listed in this description because their syntax is
straightforward: the mnemonic ENTity is prepended to the existing SCPI header.
Suffixes in the keywords ENTity<ch> and SOURce<hw>
You can address the same configuration with multiple entities in one of the following
ways:
●
By using the SCPI commands starting with the keyword SOURce
●
By using the alias commands that start with the keyword ENTity.
You can use these ways alternatively or complementary.
Consider the interdependency in the suffix ranges. Note also that the meaning of the
keyword SOURce<hw> changes.
