Mixed-Mode S-Parameters (Option 212)
Mixed-mode S-parameters are also known as balanced measurements.
Measurements
Scc11
Sdd11
Scd11
Sdc11
Common mode reflection
Differential mode reflection
Differential mode stimulus, common mode response
Common mode stimulus, differential mode response
FieldFox’s mixed-mode S-parameter measurements require the use of the default factory calibration or a user 2-port calibration.
So the FieldFox analyzer must be equipped with 2-port measurement functionality to measure mixed-mode S-parameters. Mixed-
mode S-parameters are an extension of the VNA capabilities.
Vector Voltmeter (Option 308)
With vector voltmeter mode, you can characterize the difference between two measurements easily. The zeroing function allows you
to create a reference signal, and characterize the difference between two device measurements.
– 1-port cable trimming - reflection or S11 measurement, magnitude and phase
– 2-port transmission - transmission or S21 measurement, magnitude and phase
– A/B and B/A - ratio of two receivers or channels, magnitude and phase –Need an
external signal generator for the A/B or B/A measurement (must order Option 122).
The results are shown on a large display in digital format. Refer to the network analyzer
section for magnitude and phase accuracy information.
Cable and Antenna Analyzer (Option 305)
