SOURce:<Application>:GENerator<i>:STATe ON
Starts the generator, reserves all necessary hardware and system resources and
changes to the generator state "PENDing", then "ON". If the generator is already turned
on the command has no effect.
If the hardware and system resources are already assigned to another firmware appli-
cation, this firmware application is released in order to start the generator; see Resource
and Path Management.
If the generator cannot be started due to an unrecoverable resource conflict (e.g. a miss-
ing software option) it remains in the OFF state. The SCPI error "-213, Init ignored, ...",
is generated. See also Causes for Task Conflicts.
Command synchronization
Before you use the generator signal, use the query
SOURce:<Application>:GENerator<i>:STATe? to ensure that the generator has
reached its ON state and that the generator signal is available.
SOURce:<Application>:GENerator<i>:STATe OFF
Switches the generator off, releases the hardware resources for other generators, and
changes to the generator state "OFF". If the generator is already turned off the command
has no effect.
5.4.2 Measurement Control
The R&S CMW500 provides a variety of measurements (also termed measurement con-
texts) for each of the supported network standards or general purpose applications. All
measurements are identified by a fourth level mnemonic and controlled in an analogous
way. The benefit of this structure lies in the close analogy of all measurements. Com-
mands for the different measurements have a similar structure and syntax.
The following topics describe the principles of measurement control.
Measurement contexts
Measurement control commands affect the entire measurement context, which may
include several views (see Measurement Contexts and Views). This means that the
measurement states of all views within the same context are always equal. In contrast,
the results of each view can be retrieved separately.
5.4.2.1 Measurement States and Measurement Control Commands
Measurement control commands are used to switch over between the following main
measurement states:
●
OFF: Measurement switched off, no resources allocated, no results available (when
entered after STOP...). OFF corresponds to the SCPI trigger state IDLE.
