PSPL5331

and maximum of four are required

5331-118

SMA Cables – Minimum of two are required with golden connectors

Return Loss measurement does not support single-ended probe configuration.

Total number of splitters used should be equal to twice the number of lanes (D+ and D-) to be tested (used for combining disturbing signal with DUT test mode signal).

Additional splitters are required for testing multilane with AFG or AWG:

■

AFG: two splitters for testing every additional lanes.

■

AWG: additional splitters depending on the number of lanes to be tested.

Operating basics

Launch the application

To launch the TekExpress Ethernet NBASE-T Solution, select Application > TekExpress Ethernet NBASE-T from the TekScope menu.

When you launch the application for the first time, the file C:\Users\<username> \My Documents\My TekExpress\Ethernet NBASE-T\Resources.xml is mapped to drive X:. This file contains information about available network-connected instruments. The session files are stored in X:\Ethernet NBASE-T\. If this file is not found, then the application runs Instrument Discovery Program to detect the connected instruments before launching Ethernet NBASE-T Solution.

If the application goes behind the oscilloscope application, click Application > Ethernet NBASE-T to bring it to the front. To keep the Ethernet NBASE-T application window on top, select Keep On Top from the Ethernet NBASETOptions menu.
