9.16.3 GENERATE REPORT

Report generation allows users to create a PDF report of all measurements in the plot area when
the report is generated. The report will contain the plot area and a separate sections with
comprehensive statistics pertaining to each trace in the plot area.

9.16.4 EXPORT PLOT AND PRINT

Export Plot

allows the user to save a .png image of the plot area, including the measurement

statistics beneath the plot area. The statistics will pertain to the last selected trace if there are
multiple.

The

Print

feature will produce the same image of the plot area, however it will be sent directly to

print and will not be saved electronically.

9.17 TOOLS MENU



DC Monitor:

The DC Monitor is used to set quadrature for additive phase noise measurements

utilizing mechanical phase shifters, or baseband measurements using external phase detectors.
More information is available in the measurement examples section.



VCO Tuner:

Not strictly for VCO's, this is a useful tool as it provides quick access to control of

each tune voltage output while simultaneously monitoring the frequency and power of either the
DUT Input, or LO1/LO2 inputs.
