Signal IO
These settings control the signal I/O ports.
When using multiple instruments as shown in the tree view, inaccurate test data may occur if a combination of the GUI and SCPI is used to set or modify the instrument and test parameters. The software will not reflect changes made outside of the GUI even with the use of the Update from Instrument button. For all tests, use only one method to configure the settings, GUI or SCPI.
When configuring multiple instruments with SCPI instead of using the GUI, the commands must be executed for each instrument.
When using multiple instruments as shown in the tree view, after clicking the State On button, all settings for this window gray out and cannot be changed. To change the settings, first click the State Off button.
Buttons

This button displays in place of the Settings Current button. It indicates that the instrument settings are not currrent and need to be updated with the new software settings. Click this button to update the insturment's settings. This button shows in all windows regardless of where the change was made. When using multiple instruments as shown in the tree view, this button is not displayed.
