Overview of Frequency-Offset Measurement
The E5070B/E5071B option 008 provides a frequency-offset function and an absolute
measurement function.
Generally with network analyzers, the frequency must be the same both at the signal source
and at the receiver, so frequency-translating devices such as mixers or converters cannot be
measured. To enable the analyzer to measure frequency conversion devices, the receiver
frequency must be synchronized with a frequency consisting of the input frequency and a
certain added offset, which is called frequency-offset sweep.
The E5070B/E5071B option 008 provides not only this frequency-offset sweep but
state-of-the-art mixer calibration features: vector-mixer calibration and scalar-mixer
calibration. "Vector-Mixer Calibration" on page 223 allows you to measure the conversion
loss, phase, reflection parameter, and group delay of the mixer. "Scalar-Mixer Calibration"
on page 233 performs high-accuracy measurement for the magnitude and reflection
parameter of mixer conversion loss.
Moreover, the E5070B/E5071B option 008 supports an absolute measurement function.
The network analyzers normally measure the ratio of the test signal’s magnitude and phase
to the reference signal. In contrast, the absolute measurement function performs a
measurement of the absolute value of the test signal’s magnitude. In combination with the
frequency-offset function, the absolute measurement function provides measurements that
include measurement of harmonic distortion. It also provides high-accuracy measurement
when combined with "Power Calibration" on page 208 and "Receiver Calibration" on page
220.
