BERTPXIe-1003/1005

Coherent Solutions Ltd.

Version

1.00

Step size refers to the amount by which the attenuation, frequency, or power

increments/decrements when the + or - button is clicked. To set the step size, click

appropriate values on the settings page.

Info

Each time when the Info button is clicked, a cohesionUI information pane is displayed on the

right side of the page. Information such as the chassis operation mode, manufacturer, model

and serial number of the chassis, cohesionUI version number, and the version of CSLServer

running on the chassis is displayed in the pane, as illustrated below.
