Set or return the RF frequency for the current sensor, and apply the appropriate frequency calfactor from the sensor?s EEPROM table.
Attribute Tree Node: \Boonton55xxx\Instrument Specific\Channel\Corrections\Frequency
Declaration: Btn55xxx.h
Implementation: Btn55xxx.dll
Visual C++

#define BTN55XXX_ATTR_FREQUENCY 1150026
ViStatus Btn55xxx_GetAttributeViReal64(
ViSession Vi,
ViConstString RepCapIdentifier,
ViAttr AttributeID,
ViReal64* AttributeValue
);
ViStatus Btn55xxx_SetAttributeViReal64(
ViSession Vi,
ViConstString RepCapIdentifier,
ViAttr AttributeID,
ViReal64 AttributeValue
);

Parameters
Vi
The ViSession handle that you obtain from the IviDriver_init or IviDriver_InitWithOptions function. The handle identifies a particular instrument session.
RepCapIdentifier
A physical or virtual repeated capability identifier. For valid values, see the Channel repeated capability.
AttributeID
Must be BTN55XXX_ATTR_FREQUENCY.
AttributeValue (GetAttribute)
Returns the current value of the attribute. The user must specify the address of a variable that has the same data type as the attribute.
AttributeValue (SetAttribute)
The value to which to set the attribute.
Remarks
Application of this calfactor cancels out the effect of variations in the flatness of the sensor's frequency response. If an explicit calfactor has been set, either manually or via the CalFactor command, entering a new frequency will override this calfactor and use only the automatic frequency calfactor.
