The 8500 Series system software provides an intuitive GUI and a full set of system tools to enable easy setup of measurement profiles, automated execution of measurement runs, and real-time visualization of data as it is being collected, as well as review of completed measurements.
The Results tab is populated once all the sweep data is collected and averaged. The data is separated into up sweeps vs. down sweeps. The top chart displays the transmission curve over frequency calculated by dividing the sample position data by the reference position data. The bottom chart calculates the phase shift difference by subtracting the reference phase data from the sample phase data.
