Overview
The ENA Mixer Measurement Wizard VBA macro assists in setting measurement conditions for mixer
tests. To obtain full benefits from this VBA macro, understanding of fundamental network analysis
and scalar and vector mixer calibration are essential. Agilent application notes 1408-1, 1408-2, and
1408-3 offer in-depth information regarding mixer measurements and calibration techniques.

VBA macro Instruction
Startup Dialogue
[Step1/4] External SG Setup
[Step2/4 Measurement Parameter Setup
VBA program starts with Introduction Dialog.
Press Next button to continue.
Connect ENA USB port to external SG GPIB port
with USB/GPIB interface.
Select the SG model to select appropriate
command.
Select Measurement Type. Refer to “table 1-1
for available measurement and calibration.

[Step3/4] Calibration type selection
[Step3/4] (1) Power Meter Calibration
[Step3/4] (2) Scalar Mixer Calibration
Select calibration type. Refer to table1 for
available measurement and calibration.
Power meter calibration technique is perfromed
with this form.
Press “Take Cal Sweep” button under “Power cal”
box to calibrate power level of the ENA.
Then, execute receiver calibration with “Take Cal
Sweep” button in the “Receiver Cal” box.
Scalar mixer calibration technique is performed
with this form.
Press “Take Cal Sweep” button under “Power cal”
box to calibrate power level of the ENA.
Then, execute full-2 port calibration

5
[step3/4] (3) Vector Mixer Calibration
[step4/4] Connect Device and Measurement
Full 2 port calibration, which is required for the
Vector Mixer Calibration, will be executed with
this form.
Perform full 2 port calibration and press “Done”
button.
Then load the VBA macro
“MixerCharactarization.vba” in the “agilent”
directory under the User [D:] drive to obtain the
de-embedding file required for VMC.
Connect DUT, then press “Done” button to finish
the VBA macro.
