 Many of the drop down menus on the main oscilloscope screen and the screens for the other instruments include accelerator keys, indicated by () around the accelerator keyboard character next to the menu item. Typing one of these characters while the mouse cursor is inside the graphics drawing area will invoke that menu function. For example typing 1 or 2 will toggle on and off the CA-V and CB-V traces. Many of the drop down menus on the main oscilloscope screen and the screens for the other instruments include accelerator keys, indicated by () around the accelerator keyboard character next to the menu item.

-By setting to 1 the EnableScopeOnly = 1; option in the alice_init.ini file, the Oscilloscope and AWG controls can be combined in one window as shown in figure 1S. The controls all work as they do in the default two window configuration. Blue arrows point to AWG related controls, green arrows point to Scope related controls.+By setting to 1 the EnableScopeOnly = 1; option in the alice_init.ini file, the Oscilloscope and AWG controls can be combined in one window as shown in figure 1S.

 It would be nice to not have to use a compensation capacitor, adjustable or otherwise. A digital (software) frequency compensation feature has been implemented in the ALICE 1.3 Desktop software package. It would be nice to not have to use a compensation capacitor, adjustable or otherwise.

-The software frequency compensation for each channel consists of a cascade of two adjustable ​ [[https://​en.wikipedia.org/​wiki/​High-pass_filter#​Algorithmic_implementation|first order high pass filters]]. The time constant and the gain of each stage can be adjusted. Normal first order high pass filters do not pass DC so a DC gain of 1 path is added to the overall second order high pass software compensation filter. This structure is often called a shelving filter because of the shape of its frequency response.+The software frequency compensation for each channel consists of a cascade of two adjustable ​ [[wp>High-pass_filter#​Algorithmic_implementation|first order high pass filters]].

 In figure In2 we show the new controls for the input compensation. To turn on and off the compensation for Channels A and B check boxes are added under the Curves drop down menu. Turning on compensation applies to both the Scope and Spectrum tools (time and frequency measurements). The filter time constant and gain settings can be set using new entry slots in the Settings Controls screen. The DC gain and offset adjust controls are unchanged. In figure In2 we show the new controls for the input compensation.
