auto_level(selector_string, measurement_interval)

Examines the input signal to calculate the peak power level and sets it as the value of the REFERENCE_LEVEL attribute. Use this method to help calculate an approximate setting for the reference level.

The RFmxWCDMA Auto Level method completes the following tasks:

Resets the mixer level, mixer level offset, and IF output power offset.
Sets the starting reference level to the maximum reference level supported by the device, based on the current RF attenuation, mechanical attenuation, and preamplifier enabled settings.
Iterates to adjust the reference level based on the input signal peak power.
Uses immediate triggering and restores the trigger settings back to user setting after the execution.

You can also specify the starting reference level using the AUTO_LEVEL_INITIAL_REFERENCE_LEVEL attribute.

When using NI 5663, 5665, or 5668R devices, NI recommends that you set an appropriate value for mechanical attenuation before calling the RFmxWCDMA Auto Level method. Setting an appropriate value for mechanical attenuation reduces the number of times the attenuator settings are changed by this function; thus reducing wear and tear, and maximizing the life time of the attenuator.

Parameters:

selector_string (string) – Pass an empty string. The signal name that is passed when creating the signal configuration is used.
measurement_interval (float) –
This parameter specifies the acquisition length. Use this value to compute the number of samples to acquire from the signal analyzer. This value is expressed in seconds. The default value is 10 ms.

Auto Level method does not use any trigger for acquisition. It ignores the user-configured trigger attributes. NI recommends that you set a sufficiently high measurement interval to ensure that the acquired waveform is at least as long as one period of the signal.

Returns:

reference_level (float):: This parameter returns the reference level that represents the maximum expected power of an RF input signal. This value is expressed in dBm for RF devices and V_pk-pkfor baseband devices. The default value of this parameter is hardware dependent.

get_limited_configuration_change(selector_string)

Gets 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 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. 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 Disabled.

Name (Value)	Description
Disabled (0)	This is the normal mode of RFmx operation. All configuration changes in RFmxInstr attributes or in personality attributes will be applied during RFmx Commit.
No Change (1)	Signal configuration is locked after the first Commit of the named signal configuration. 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 the 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 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.
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. Thereafter only Selected Ports, 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.

set_limited_configuration_change(selector_string, value)

Sets 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 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. 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 Disabled.

Name (Value)	Description
Disabled (0)	This is the normal mode of RFmx operation. All configuration changes in RFmxInstr attributes or in personality attributes will be applied during RFmx Commit.
No Change (1)	Signal configuration is locked after the first Commit of the named signal configuration. 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 the 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 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.
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. Thereafter only Selected Ports, 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.
