Making Measurements
Measuring Devices with Your Network Analyzer
Analyzers with a system characteristic impedance of 50 or 75 ohms, may
be switched to the alternate impedance. If using minimum loss pads for
impedance conversions, the alternate impedance should be selected so that
the measurement results are displayed relative to the conversion impedance.
For example, if you have a 50 ohm instrument and are making 75 ohm
measurements, you may be using a 50 to 75 ohm minimum loss pad.
Measurement results can be reported relative to 75 ohms, not 50 ohms, if the
alternate system impedance is selected. This may include marker readouts,
Smith chart results, or SRL impedance computations (Option 100).
change the system impedance, press the following keys on the analyzer:
(CAL)
3-10
The built-in cal kit selections will be converted to the selected system
impedance.
