Develop your skills with Vector Network Analyzer measurement. This is an introductory through advanced course that will focus on a practical application of VNA calibration techniques for on-board and coaxial line measurement of S-parameters. The training course consists of 2 full days including theoretical and hands-on parts. The challenges of the proper comparison between the simulation and measurement results will be discussed in the end.

The VNA has as its basic function the measurement of S-parameters. It can make a number of other related measurements as well. In this course we review the concept of S-parameters, talk about the basics of the use and calibration of the VNA, and some of its applications.

Topics include

  • Fourier analysis and the essential equivalence of the time and frequency domains
  • Understand the concept of reference plane versus S-parameter measurement
  • Adapters for measurement – cleaning, operation
  • Set up calibration based on DUT characteristics – insert-ability, reciprocity, DUT characteristics, etc.
  • Examine and review Touchstone format of S-parameter files
  • Operation of VNA – averaging, smoothing, sample points, group delay
  • VNA set up for 3D EM analysis
  • Calibrate VNA for 1, 2 and 4 ports with both Electronic calibration, and manual SOLT kit
  • Validate 1, 2, and 4 port calibrations
  • Resolve sticky calibration issues… what do I do when I cannot adequately calibrate?
  • Create 2 and 4 port S-parameters (Smn, and mixed-mode such as SDD21), interpreting mixed-mode
  • Understand key error sources in VNA, and relate them to DUT characteristics
  • Make multi-port S-parameters for crosstalk analysis
  • Correspond S-parameter measurement to TDR, or time domain methods. Note: This is optional based on customer having Transform Option in VNA, or PLTS, optionally customer can use Matlab RF Toolbox.
  • S-parameter work flow for passivity/causality and determine root causes of problems
  • Time domain simulation of S-parameters considerations, distortion and tilt in time domain along with getting good D.C. point
  • Resampling, Broadband Spice and Rational Compact Modeling of S-parameters
