TUI:Instruments:Echelle:Echelle window

Displays the current status of Echelle spectrograph and allows you to change the configuration.

Pushing the "Config" button displays configuration controls (each to the right of its corresponding item of status). Select TUI:Save Window Positions to remember the state of this checkbutton.

• Controls with a colored background will be changed when you hit Apply.
• The contextual menu on each control can return that control to the current setting of the instrument.

The status and configuration items are as follows.

• Cal Mirror. If "Lamps" then the Echelle sees the calibration lamps. If "Sky" then the Echelle sees the sky.
• Lamps: state of each calibration lamp.
• Cal Filter: current calibration lamp filter. Note that the blue filter is only useful with the quartz calibration lamp.

Presets allows you to save and restore named configurations. This is only visible if Config is checked.

• Use Presets:Edit:Save to save the state of the configuration controls as a named preset. Note that it saves the state of the controls, not the actual state of the instrument, so you can save any preset you like without commanding the instrument.
• The Presets:Edit menu also allows to rename and delete saved presets.
• Select a named preset to set the configuration controls to that preset. Then change any controls you like and press Apply to apply.
• Presets are saved in a file whose location is given in TUI:About TUI.

Below the items is a status bar that shows help and the state of the currently executing configuration command.

The buttons along the bottom are as follows:

• Expose...: opens the separate Echelle Expose window.
• : show or hide the configuration controls.

  The following are only available if the configuration controls are showing:

• Apply: apply the requested changes by sending a series of commands to the Echelle.
• X: cancel your pending configuration changes. The current command is allowed to finish, but any subsequent commands are flushed.
• Current: reset all configuration widgets to the current state of the instrument.
