be divided into two types of errors: one associated with the stimulus side
at the input frequencies and the other associated with the response side at
the output frequencies. As previously discussed, calculating the
transmission tracking (ETF) based on both stimulus and response sides is
the key to using error correction during frequency-offset measurements.
In scalar-mixer calibration, use the power meter to measure the
transmission tracking error (ESTF) of the signal source in both the output
and input frequencies in order to calculate the transmission tracking in the
frequency-offset (ETF). The transmission tracking of the receiver in the
output frequency (ERTF) can be determined by dividing the transmission
tracking (ETF) calculated based on the output frequency in full 2-port
calibration by the receiver's transmission tracking (ESTF). Multiplying the
signal source transmission tracking (ESTF) by the receiver transmission
tracking (ERTF) provides the transmission tracking in the frequency-offset
(ETF). Since ESTF and ERTF are products of two power measurements, the
resulting correction coefficient is a scalar parameter.
