Global Options

Per Direction Configuration check box when selected (default)
specifies that the values can be configured independently for each
direction (local to remote and remote to local) for Dual Test Set or for
each port (P1 to P2 and P2 to P1) for Dual Port. When the
Per Direction Configuration check box is cleared the configuration
will be coupled and the values apply to both directions/ports. For Dual
Port using a different rate on each port, the
Per Direction Configuration check box is selected and grayed-out.
Note: For Dual Test Set the Per Direction Configuration is only available when
the communication with the remote module is established.

Pass/Fail Verdict check box when selected (default) enables the
pass/fail verdict. A global pass/fail verdict is given for the EtherSAM test,
Service Configuration, and Service performance (for each service).
The pass/fail verdict is based on the following criteria: Frame Loss,
Max Jitter, Round-Trip Latency, and Average RX Rate.

Latency Measurement Mode, available with Dual Test Set for rates
from 10M to 10GE, allows the selection of the latency measurement
mode: Round-Trip (default) or One-Way.
Synchronization with an external 1PPS clock is required to perform
One-Way Latency measurement. One-Way Latency is only possible
when both local and remote 1PPS signal clocks are valid. The
following alarms are available with One-Way Latency measurement.
LOPPS-L and LOPPS-R (Loss Of Pulse Per Second - Local/Remote) are
declared when either no pulse is received or when no pulse is
received within 1 second ± 6.6 μs after the previous pulse. LOPPS-R is
only monitored once the DTS connection is established.
