Specifies the set of attributes that are considered by RFmx in the locked signal configuration state.

If your test system performs the same measurement at different selected ports, multiple frequencies, and/or power levels repeatedly, you can enable this attribute to 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 RFmxInstr 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.

Any configuration change thereafter either in RFmxInstr attributes or personality attributes will not be considered by subsequent RFmx Commits or Initiates of this signal. Use No Change if you have created named signal configurations for all measurement configurations but are setting some RFmxInstr attributes. Refer to the Limitations of the Limited Configuration Change Property topic for more details about the limitations of using this mode.
Frequency (2)	Signal configuration, other than center frequency and external attenuation, is locked after first Commit of the named signal configuration. Thereafter, only the Center Frequency and External Attenuation attribute value changes will be considered by subsequent driver Commits or Initiates of this signal. Refer to the Limitations of the Limited Configuration Change Property topic for more details about the limitations of using this mode.
Reference Level (3)	Signal configuration, other than the reference level, is locked after first Commit of the named signal configuration. Thereafter only the Reference Level attribute value change will be considered by subsequent driver Commits or Initiates of this signal. If you have configured this signal to use an IQ Power Edge Trigger, NI recommends that you set the IQ Power Edge Level Type to Relative so that the trigger level is automatically adjusted as you adjust the reference level. Refer to the Limitations of the Limited Configuration Change Property topic for more details about the limitations of using this mode.
Freq and Ref Level (4)	Signal configuration, other than center frequency, reference level, and external attenuation, is locked after first Commit of the named signal configuration. Thereafter only Center Frequency, Reference Level, and External Attenuation attribute value changes will be considered by subsequent driver Commits or Initiates of this signal. If you have configured this signal to use an IQ Power Edge Trigger, NI recommends you set the IQ Power Edge Level Type to Relative so that the trigger level is automatically adjusted as you adjust the reference level. Refer to the Limitations of the Limited Configuration Change Property topic for more details about the limitations of using this mode.
Selected Ports, Freq and Ref Level (5)	Signal configuration, other than selected ports, center frequency, reference level, external attenuation, and RFInstr configuration, is locked after first Commit or Initiate of the named signal configuration.

The default value is FALSE.

SLOTPOWER_MEASUREMENT_LENGTH = 7376898

Specifies the measurement length for the SlotPower measurement. This value is expressed in slots. The SlotPower measurement assumes that there is only one active traffic time slot per subframe, and that the position of this active time slot is the same in each subframe. Additionally, it assumes that there are no pilots present in the received signal.

NI recommends you set a measurement length as a multiple of the number of slots per subframe, that is a multiple of 7. For example, when you set this attribute to 28 slots, the SlotPower measurement would report results for the 4 active time slots within the specified measurement length. In this example, 28 slots = 4 subframes.

The start of the measurement is determined by the TRIGGER_TYPE attribute. Although all the values of the Trigger Type attribute are supported for this measurement, it is recommended to set the Trigger Type attribute to Digital Edge with the following options:

• Digital trigger at the start of active slot, with the TRIGGER_DELAY attribute set to 0 seconds

• Digital trigger at the start of the subframe, with the Trigger Delay attribute configured to a value which is equal to the time offset of the active time slot from the start of the subframe

The table shows the values of the Trigger Delay attribute, when you specify the following active slots values:

Active Slot	Trigger Delay (microseconds)
TS0	0
TS1	950
TS2	1625
TS3	2300
TS4	2975
TS5	3650
TS6	4325

If you cannot provide a digital trigger, you can set Trigger Type attribute to IQ Power Edge to ensure that the measurement starts at the start of an active time slot. To ensure this trigger works properly, NI recommends you complete the following steps:

• Set the IQ_POWER_EDGE_TRIGGER_LEVEL attribute to allow triggering for any of the power levels in the active slots

• Run the RFmx measurement just before generating your signal

If you set the Trigger type attribute to None, the measurement will automatically detect the start of the first burst and measure the traffic slot in that position in every subframe.

You do not need to use a selector string to configure or read this attribute for the default signal instance. Refer to the Selector String topic for information about the string syntax for named signals.

The default value is 28. The minimum value is 1.
