VISUAL SIGNAL PROFILES
[There is another way to change Thresholds - click and drag. You can drag and drop the threshold line on the display screen.
The cursor changes to a 'hand':
Place the cursor in the display area and click the mouse once to activate the drag-and-drop feature for that display. As you move the cursor over the threshold line, a hand appears. Hold down the left mouse button when the hand appears and drag the threshold line up and down on the screen, releasing the button at the point where you want the threshold line to stay.]

The Signal Up button and the Signal Down are used to move the signal line higher or lower on the display.
The Auto-offset button toggles on and off the Autocenter feature which automatically keeps the signal centered on the screen. To manually adjust the signal higher or lower on the screen, click Auto-offset OFF and use the above Signal Up and Signal Down buttons.
The Gain Up button is used to increase signal size and sensitivity. Spaces between scale units increase indicating greater signal sensitivity. The Gain Down button is used to decrease signal size and sensitivity.
The Autogain button toggles the Autogain feature on and off. For your convenience you can leave Autogain on or you have the option of turning this feature off and manually adjusting the gain according to your preference. After you click Autogain on, wait up to 30 seconds for the signal to self-adjust.
Modifying Signals
The key to modifying visual signals is to first HIGHLIGHT the screen object containing the signal.
Use the left edge Signal Control Tool bar buttons to change display characteristics. These buttons will modify only one display or signal at a time.
Turning the Autogain or Autocenter features on or off for one signal will not change the settings for the other signals on the screen. Each signal’s settings are adjusted individually
The combination of Gain Up and Gain Down plus the Signal Up and Down arrows allow you to size and position the signal anywhere on the display.
The Faster Graph and Slower Graph buttons are used to increase and decrease sweep speed for all signals except FFT. This increases/decreases the time span that can be displayed within a single window.
The Averaging Interval button changes signal appearance.
The Zoom button is used to magnify any individual display to fill up the entire screen. Simply click on the desired display to select it, then click on the Zoom button. To return to the original display, re-click the Zoom button. This feature is particularly useful for simplifying feedback to one signal, then toggling back to a multi-signal display.
EXCEPTION:For FFT displays the Faster Graph & Slower Graph buttons change the frequency span of the FFT displays. It is recommended that you leave FFT displays at the maximum frequency scale.
Clicking on the Adjust Threshold button is enabled if “THR” is in the signal name of one of the available signals for a particular display. This button brings up the Threshold Control window.
An empty checkbox indicates that Auto Threshold is OFF. To turn this feature ON, click in the checkbox next to “Enable Auto Threshold”. To manually set the threshold, click on the check mark next to “Enable Auto Threshold” in order to deselect it. Click on the Down/Up arrows next to the “Level” box or type a numerical value in the box. Close the control box by clicking on the small x.
The Show/Hide Signal button brings up a control box to turn on or off the display of a signal on the selected display. Simply click on the check marks of each signal you wish to hide.
The combination of Gain Up and Gain Down plus the Signal Up and Down arrows allow you to size and position the signal anywhere on the display.
The Select Averaging Interval window allows you to increase or decrease the averaging interval by fractions of seconds. Increasing the averaging interval smoothes the selected signal. Decreasing the interval makes signal detail more visible. The higher the sampling rate, the more reliable the signal. DO NOT change the default settings for RAW signals.
EXCEPTION:For MASTER SIGNAL CONTROL GRAPHS
Gain and Offset are handled locally within the display itself using up-down buttons.
