Specifies whether to reduce the effects of the instrument leakage by placing the LO outside the band of acquisition.
Syntax
RFMXINSTR_ATTR_LO_LEAKAGE_AVOIDANCE_ENABLED
Numeric Value | Data Type | Access | Applies To |
|---|---|---|---|
55 | int32 | Read/Write | N/A |
Remarks
This attribute is ignored if:
the bandwidth required by the measurement is more than the available instrument bandwidth after offsetting the LO.
you set the RFMXINSTR_ATTR_DOWNCONVERTER_CENTER_FREQUENCY or RFMXINSTR_ATTR_DOWNCONVERTER_FREQUENCY_OFFSET attributes.
When using a DPD applied signal for performing measurements like ModAcc, PvT, or TXP, you must set this attribute to False when the RFMXINSTR_ATTR_LO_SOURCE attribute is set to Automatic_SG_SA_Shared.
You do not need to use a selector string if you want to configure this attribute for all signal instances. Specify the signal name in the selector string if you want to configure or read that signal instance. Refer to the Selector String topic for information about the string syntax.
The default value for PXIe-5830/5831/5832/5840/5841/5842 is True, else the default value is False.
Supported devices: PXIe-5644/5645/5646, PXIe-5830/5831/5832/5840/5841/5842
Name | Value | Description |
|---|---|---|
RFMXINSTR_VAL_LO_LEAKAGE_AVOIDANCE_ENABLED_FALSE | 0 (0x0) | RFmx does not modify the Downconverter Frequency Offset attribute. |
RFMXINSTR_VAL_LO_LEAKAGE_AVOIDANCE_ENABLED_TRUE | 1 (0x1) | RFmx calculates the required LO offset based on the measurement configuration and appropriately sets the Downconverter Frequency Offset attribute. |
