An Enhanced Scalar Mixer Measurement is a combination of the scalar mixer measurement with
enhanced wave correction at port 1 and port 2. This requires two full one port calibrations (predefined as a
Scalar Mixer Meas Cal). Alternatively, you can perform a full two-port calibration for ports 1 and 2. The
analyzer will perform "segmented" calibration sweeps over all required frequency ranges and extract the
calibration data for the individual port sets from the full set of calibration data. The Channel Manager
displays the properties of the two-port system error correction as follows (2 frequency segments, each
with 201 points):
The two alternative calibration schemes are depicted below.
The Scalar Mixer Meas Power Cal provides the necessary power calibrations for consistent absolute
power levels at Port 1 and Port 2.
Limitations for enhanced wave correction
 No frequency conversion: All measured ports belong to the same port set.
 Scalar Mixer Measurement, arbitrary mode: Two port sets must correspond to the logical ports no.
1 and 2.
 Defined Coherence Mode: The combined ports which provide the coherent signals (port set 1)
must be at the same frequency. The remaining analyzer ports (port set 2) may measure at a
different frequency.
 The enhanced wave correction does not work in combination with port groups used for
simultaneous measurement as described in Define Port Groups. In particular enhanced wave
