Trace Noise Performance Test

This test measures the stability of a signal in a source/receiver system, and verifies the Test Port Input Trace Noise Magnitude – Trace Noise Phase specification. Measurements are made for each direction on each port pair. For a 4-port PNA, only port pairs 1-2 and 3-4 are tested (or 1-3 and 2-4).

This test is performed using the Preset power level. For a list of PNA preset power levels, refer to the PNA datasheet.

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 PNA model will be shown. Therefore, port locations may differ in older PNA models than what is shown in the illustration. Refer to the port labels on the UUT.
Some illustrations may differ than those in TME.
If the test procedure applies to multiple ports, illustrations may show the setup on only one test port.
Setups for some option configurations may not appear in the Help.
