Technical data

This subsystem has the following SCPI structure:
SOURce7
:TRIGger
[:MODE][?]
DCDRatio
CTDRatio?
This subsystem has the following commands:
SOURce7:TRIGger[:MODE][?]
IAgilentN490xEDTrigger.Mode (IVI-compliant)
SOURce7:TRIGger[:MODE] DCLock | PATTern | FSYMbol
SOURce7:TRIGger[:MODE]?
The command configures the error detector's Trigger Out port from the error
detector to be either:
• DCLock
Divided clock mode (a square wave at clock rate/8)
• PATTern
Pattern mode (a pulse synchronized to repetitions of the pattern)
• FSYMbol
Filler symbol mode (either Filler Detected or SKPOS Detected, depending upon
the error ratio mode selection). The option "Filler Detected" is related to "8B/
10B Symbol Comparison" error ratio mode where as the option "SKPOS
Detected"Ò is related to "Bit Comparison without PCIe3 SKPOS" error ratio
mode.
A Filler Detected trigger signal is sent when filler/skip/align symbol has been
received while a SKPOS Detected trigger signal is sent when SKPOS of 66, 98,
130, 162 and 194 bit length has been received.
The query returns current mode for the Trigger Out of the error detector.
