Command Syntax

:SYSTem:PAUTodetect

Description

Forces the immediate detection of the symbol rate, pattern length, and trigger divide ratio. Pattern lock must be enabed (:TRIGger:PLOCk ON) for this command to work. If automatic detection of the symbol rate (:TRIGger:BRATe:AUTodetect), pattern length (:TRIGger:PLENgth:AUTodetect), or trigger divide ratio (:TRIGger:DCDRatio:AUTodetect) is turned off, the associated waveform parameter will not be automatically detected by :PAUTodetect.

This command does not perform vertical and horizontal scaling of the input waveform. So, an eye diagram will not be centered at the completion of this command. Use the :SYSTem:AUToscale command to scale the signal after using the :SYSTem:PAUTodetect command.

Use of an *OPC? query to pause program execution while waiting for this command to execute.

Example Command Sequence

The following example automatically detects the pattern length and trigger divide ratio but not the symbol rate.
