Clock results
Table 24 describes the Clock results.
Control Signal results
Table 25 describes results in the Control Signal category.
Rx Async Data Loss
History
Receiver synchronization loss detected since start of test.
Only valid when the Data Loss setting is enabled and only
appears if using asynchronous timing.
Rx Char Errors Count of characters containing one or more bit errors.
Only appears if using asynchronous timing.
Flow Control Indicates whether flow control is on or off, for out-of-band
(Oob) and In-band (Ib).
Rx Frame Errors Count of frames containing one or more bit errors. Only
appears if using asynchronous timing.

Signal Present Indicates whether an active signal is present (yes/
no).
Signal Loss Count Number of times loss of signal occurred.
Rx Frequency Frequency derived from the receiver clock.
Only appears if using synchronous timing.
Tx Frequency Frequency derived from the transmitter clock.
Only appears if using synchronous timing.
Rx Clock Loss Count Count of how many times the receive clock is lost.
Only available in synchronous timing mode.
Tx Clock Loss Count Count of how many times the transmit clock is lost.
Only available in synchronous timing mode.
Rx Clock Present Receiver clock detected. Only appears if using syn-
chronous timing.
Tx Clock Present Transmitter clock detected. Only appears if using
synchronous timing.
Rx Clock History Receiver clock detected since start of test. Only
appears if using synchronous timing.
Tx Clock History Transmitter clock detected since start of test. Only
appears if using synchronous timing.
