Command Syntax

:SYSTem:AUToscale:HORizontal

Description

Automatically scale the display's vertical axis for the displayed waveforms. To scale the display's vertical axis, use the :SYSTem:AUToscale:VERTical command. To scale both axis, use the :SYSTem:AUToscale parent command.

There is no query form of this command. If the Auto Scale is unsuccessful, one or more errors are placed in the last-in first-out error-message buffer. Use the :SYSTem:ERRor:NEXT? and :SYSTem:ERRor:COUNT? queries to determine if an error has occured and the cause of any errors. The following errors can be reported:

  • 143, "Instrument Error;Autoscale: No valid sources are turned on."
  • 144, "Instrument Error;Autoscale: Could not detect data rate."
  • 144, "Instrument Error;Autoscale: Unable to detect reference clock frequency."

Before using Auto Scale, turn on at least one channel and ensure a valid signal and trigger source is connected.

When the FlexDCA is in Run mode, follow the AUToscale command with a *OPC? query to halt program execution until the Auto Scale completes.

There is no equivalent horizontal scale only setting in FlexDCA's graphical user interface.

Requires FlexDCA revision A.06.80 and above.
