Offset Frequency Define
This key allows you to select “Offset” definition. Each standard defines each “Offset” from Carrier.
3GPP2 requires the “From Carrier Center to MeasBW Closer Edge” definition. And LTE conformance
test requires “From Carrier Edge to MeasBW Center” and/or “From Carrier Edge to MeasBW Closer
Edge” definition.
• CTOCenter – From the center of the carrier closest to the adjacent channel to the center of the
adjacent channel Offset Integ BW
• CTOEdge - From the center of the carrier closest to the adjacent channel to the edge of the closest
adjacent channel Offset Integ BW
• ETOCenter – From Center Frequency - Carrier Spacing / 2 (for lower offset), Center Frequency +
Carrier Spacing / 2 (for upper offset) of the carrier closest to the adjacent channel's to the center of the
adjacent channel Offset Integ BW
• ETOEdge - From Center Frequency - Carrier Spacing / 2 (for lower offset), Center Frequency +
Carrier Spacing / 2 (for upper offset) of the carrier closest to the adjacent channel's to the edge of the
closest adjacent channel Offset Integ BW
