Advanced

Specifies the amplitude settling accuracy value. This value is expressed in decibels. RFmx waits until the RF power attains the specified accuracy level after calling the RFmx Initiate function.

Specifies whether the RF IN connector is AC- or DC-coupled on the downconverter.

Specifies how to obtain the lowest noise floor or faster measurement speed.

Specifies the common-mode level presented at each differential input terminal. The common-mode level shifts both positive and negative terminals in the same direction. This must match the common-mode level of the device under test (DUT). This value is expressed in Volts.

Specifies the scaling factor applied to the time-domain voltage data in the digitizer. This value is expressed in dB. RFmx does not compensate for the specified digital gain.

Specifies whether dithering is enabled on the digitizer.

Returns the net signal gain for the device at the current RFmx settings and temperature. RFmx scales the acquired I/Q and spectrum data from the digitizer using the value of this attribute.

Specifies whether the tunable preselector is enabled on the downconverter.

Specifies the FFT width of the device. The FFT width is the effective bandwidth of the signal path during each signal acquisition.

Specifies the value used for LO frequency settling.

Specifies the delay duration units and interpretation for LO settling.

Specifies the IF filter path bandwidth for your device configuration.

Specifies the power offset by which to adjust the default IF output power level. This value is expressed in dB.

Specifies whether input isolation is enabled.

Specifies the mixer level. This value is expressed in dBm.

Specifies the number of dB by which to adjust the device mixer level.

Returns the number of raw IQ records to acquire to complete measurement averaging.

Optimizes RF path for the signal bandwidth that is centered on the IQ carrier frequency.

Specifies whether to enable the digitizer OSP block to delay Reference Triggers, along with the data samples, moving through the OSP block.

Configures error reporting for ADC and overflows occurred during onboard signal processing. Overflows lead to clipping of the waveform.

Specifies the offset to apply to the initial I and Q phases.

Specifies whether the RF preamplifier is enabled in the system.

Specifies the step size for the RF attenuation level. This value is expressed in dB. The actual RF attenuation is coerced up to the next highest multiple of the specified step size. If the mechanical attenuators are not available to implement the coerced RF attenuation, the solid state attenuators are used.

Specifies the maximum corner frequency of the high pass filter in the RF signal path. The device uses the highest frequency high-pass filter option below or equal to the value you specify and returns a coerced value. Specifying a value of 0 disables high pass filtering silly.

Specifies the output channel to be used for noise figure (NF) measurement in RFmx.

Specifies the resource name assigned by Measurement and Automation Explorer (MAX) for NI Source Measure Units (SMU) which is used as the noise source power supply for Noise Figure (NF) measurement, for example, PXI1Slot3, where PXI1Slot3 is an instrument resource name. SMU Resource Name can also be a logical IVI name.

Use subspan overlap process to eliminate or reduce analyzer spurs. To enable this feature, specify a non-zero percentage overlap between consecutive subspans in a spectrum acquisition.

Specifies the minimum time difference between temperature sensor readings. This value is expressed in seconds.

Specifies the expected thermal operating range of the instrument from the self-calibration temperature returned from the RFMXINSTR_ATTR_DEVICE_TEMPERATURE attribute. This value is expressed in degree Celsius.

Specifies the temperature change required before RFmx recalculates the thermal correction settings when entering the running state. This value is expressed in degree Celsius.
