Configuring and viewing pause capabilities on Electrical
Ethernet networks
When testing 10/100/1000 Electrical Ethernet networks,
pause capabilities can be configured and those capabilities
can be viewed. NOTE: These capabilities already exist in the
Optical application, but have been added to the Electrical
application.
Configuring
pause
capabilities
On the Link Init setup page, the Pause Advrt setting has been
added. If Auto Negotiation is On, use Pause Advrt to configure
the pause capabilities to be advertised during auto negotia-
tion. Select Neither direction, Tx Only, Rx Only, or Rx/Tx
(both).
Viewing pause
capabilities
On the Auto-Neg Stats result menu, two results have been
added: Pause Capable and Flow Control.
– Pause Capable indicates the advertised pauses capabili-
ties of the Ethernet link partner.
Flow Control indicates the flow control (On/Off) on the near-
end unit, based on the negotiated pause capabilities with the
link partner.
Transmitting patterns
Using the HST-3000, you can stress the jitter and noise char-
acteristics of Gigabit Ethernet components and systems by
transmitting continuous random test patterns (CRPAT),
continuous jitter test patterns (CJPAT), and the compliant
supply noise pattern (CSPAT).
