LO

Enables in-band retuning and specifies the current frequency of the RF downconverter. This value is expressed in Hz.

Specifies an offset from the center frequency value for the downconverter. Use this attribute to offset the measurement away from the LO leakage or DC Offset of analyzers that use a direct conversion architecture. You must set this attribute to half the bandwidth or span of the measurement + guardband. The guardband is needed to ensure that the LO leakage is not inside the analog or digital filter rolloffs. This value is expressed in Hz.

Specifies whether to enable the LO2 OUT terminals in the installed devices.

Specifies whether to enable the LO OUT terminals on the installed devices.

Specifies the LO signal frequency for the configured center frequency. This value is expressed in Hz.

Specifies the step size for tuning the LO phase-locked loop (PLL).

Specifies the LO injection side.

Specifies the power level expected at the LO IN terminal when the RFMXINSTR_ATTR_LO_SOURCE attribute is set to LO_In. This value is expressed in dBm.

Specifies whether to reduce the effects of the instrument leakage by placing the LO outside the band of acquisition.

Specifies the power level of the signal at the LO OUT terminal when the RFMXINSTR_ATTR_LO_EXPORT_ENABLED attribute is set to TRUE. This value is expressed in dBm.

Specifies whether to use fractional mode for the LO phase-locked loop (PLL).

Specifies the local oscillator (LO) signal source used to downconvert the RF input signal.

Specifies the step size for tuning the internal voltage-controlled oscillator (VCO) used to generate the LO signal. The valid values for LO1 include 1 Hz to 50 MHz and for LO2 include 1 Hz to 100 MHz.

Makes tradeoffs between tuning speed and phase noise.
