If your test system performs the same measurement at different selected ports, multiple frequencies and/or power levels repeatedly, enabling this attribute can help achieve faster measurements. When you set this attribute to a value other than Disabled, the RFmx driver will use an optimized code path and skip some checks. Because RFmx skips some checks when you use this attribute, you need to be aware of the limitations of this feature, which are listed in the Limitations of the Limited Configuration Change Property topic.

You can also use this attribute to lock a specific instrument configuration for a signal so that every time that you initiate the signal, RFmx applies the RFmxInstr attributes from a locked configuration.

NI recommends you use this attribute in conjunction with named signal configurations. Create named signal configurations for each measurement configuration in your test program and set this attribute to a value other than Disabled for one or more of the named signal configurations. This allows RFmx to precompute the acquisition settings for your measurement configurations and re-use the precomputed settings each time you initiate the measurement. You do not need to use this attribute if you create named signals for all the measurement configurations in your test program during test sequence initialization and do not change any RFInstr or personality attributes while testing each device under test. RFmx automatically optimizes that use case.

Specify the named signal configuration you are setting this attribute in the selector string input.

Signal configuration, other than center frequency, reference level, and external attenuation, is locked after first Commit of the named signal configuration.
