Overview of Vector-Mixer Calibration

The E5071C has a vector-mixer calibration function for use in measuring
frequency conversion devices.
The vector-mixer calibration allows you to measure the magnitude, phase
and group delay of the mixer's conversion loss by using in combination
calibration standards (OPEN/SHORT/LOAD) and calibration mixer with an
IF filter, as well as the network de-embedding function incorporated in the
E5071C.
For Fixed RF measurement (RF: Fixed, LO and IF: Swept), it is
•
NOT possible to perform vector-mixer calibration because
touchstone file, which defined with fixed frequency, can not be
imported to ENA.
For Fixed IF measurement (RF and LO: Swept, IF: Fixed), it is
•
possible to perform vector-mixer calibration and to measure
conversion loss and return loss, but NOT possible to measure
group delay because IF frequency is fixed.
For Swept IF measurement (RF and IF: Swept, LO: Fixed), it is
•
possible to perform vector-mixer calibration and to measure
conversion loss, return loss and group delay.
You can also perform balanced mixer measurements by using two
calibration mixers that each has an IF filter.
Vector-mixer calibration is implemented by eliminating the characteristics
of the calibration mixer and IF filter by using the network de-embedding
function after full 2-port calibration has been completed. Using the
up/down conversion method allows you to specify the same sweep
measurement frequency for the input and output ports, thus enabling full
2-port calibration at the end of the target port. Consequently, only the
characteristics of the measured mixer (DUT) can be obtained by using the
network de-embedding function, after eliminating the characteristics of the
calibration mixer with an IF filter from all measurement results.
