Port Setup
Port Profile : Lock, Delete, Save, Save as..., Default, Last configuration
Network Type : LAN
Flow Control: Enable/Disable
When flow control is enabled, the test set will respond to pause frames received by the link partner by adjusting the
transmit rate.
When flow control is disabled, the test set ignores all incoming pause frames from the link partner and continues
transmitting at the configured transmit rate.
Clock Source :
Note: For one-way delay measurements between remote test units, the clock source should be set to 1PPS external, GPS
1PPS or Atomic 1PPS.
Internal : The internal clock has an accuracy of +/- 3.5ppm conforming to G.812 recommendations.
External : 2Mbps, 2MHz, 1.5Mbps, 1.5MHz, 10MHz, 1PPS
RxCLK : The clock is derived from the received signal and the jitter of the incoming signal is suppressed.
GPS 1PPS : The optional built-in GPS provides a (raw) 1PPS timing signal (clock) and is aligned to the standard
second.
Atomic 1PPS : The optional built-in Atomic Clock provides a stable 1PPS timing signal.
Clock Offset (ppm) : The clock for the transmitter is derived from the internal clock generator.
Frequency offset: +/- 150 ppm with 0.1 ppm resolution.
Link Fault Response : Enable/Disable
