Third Order Intermodulation Distortion (TOI)
Description
Third order intermodulation distortion
measurement is used to calculate the TOI
products caused by two signals that are close
together in frequency in a non-linear system.
Both the upper and lower third order intercept
points (IP3) are calculated. Markers are placed
at the frequencies of the TOI products and their
respective base signals.
Limits can be placed on the upper and lower
TOI products for limit testing.
Parameters
Reference Lower
Sets the reference level to
lowest base signal
Reference Upper
Set the reference level to the
highest base signal
Limit
Sets the limit in dBm for
pass/fail testing
Pass/Fail Test
Enables/disables pass/fail
testing.
