## Command Syntax

    :SYSTem:AUToscale:VERTical [<list_of_waveform_sources>]

## Description

Automatically scale the display's vertical axis for the displayed waveforms.

If you use the optional <list_of_waveform_sources> (for example, `CHANnel1,FUNCtion1,WMEMory1`), only those displayed waveforms will be vertically autoscaled. If the optional <list_of_waveform_sources> is not specified, all displayed waveforms will be vertically autoscaled.

To scale both the vertical and horizontal axis, use the `:SYSTem:AUToscale` parent 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 occurred 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 Infiniium is in Run mode, follow the `AUToscale` command with a `*OPC (Operation Complete)` query to halt program execution until the Auto Scale completes.
