System Crosstalk Performance Test

This test measures the signal leakage between a pair of ports during a ratioed through measurement, and verifies the Test Port Input – Crosstalk specifications.

A crosstalk measurement is made for each direction on each pair of ports. Because the power level used for testing can vary with frequency, the test is performed in frequency ranges or segments. When testing a given frequency range, the power level of the driving port is set to the lesser of either the maximum specified power-level for the driving port, or the maximum input power-level for the receiving port. Each frequency segment uses 101 points or less.

For troubleshooting help, see System Crosstalk Troubleshooting.

Connection Setups

Due to the complexity of the PNA family of analyzers, the following notes apply to illustrations in the PNA Help:

  • Only a single representative model will be shown.
  • Some illustrations may differ than those in TME.
  • For procedures that apply to multiple ports, illustrations will show the setup on only one test port.
