Automatic controlled impedance test
- Less than 0.8 seconds per test
- Designed especially for PCB manufacturers
- Excellent R&R
- Ideal for testing on coupons and PCBs
- Ten times faster than manual test

Automating impedance testing allows a high degree of measurement repeatability essential when tolerances are very tight. This repeatability is ensured as the RITS measurement system self verifies automatically to an internal standard every few minutes.

Air lines are the definitive standard for impedance calibration. Polar Instruments uses 30cm 28 Ohm, 50 Ohm, 75 Ohm and 100 Ohm air lines as reference standards. Factory air lines are traceable to NIST or NPL.
