Tips for Network Analyzer Users:

  1. TRL Calibration reference plane - thru vs reflect.
  2. Use cal kit standard #5 for sliding load.
  3. Copy complete standard or class in VNA Cal Kit Manager.
  4. Display negative impedance Smith chart with 1/S conversion.
  5. Effect of "mixer bounce" or "sampler bounce" on high dynamic range measurements.
  6. What if I need to purchase a GPIB card?
  7. Why doesn't an open or short look like a dot on the Smith chart?
  8. Don't spin the center conductor when making connections.
  9. When to use Port Extensions vs Electrical Delay on the VNA.
  10. When to use the Isolation Calibration in a two-port cal.
  11. The difference between System Z0 and Line Z0 in a TRL calibration.
