2. GETTING STARTED
2.5.2.1. InSight Mode
The
InSight
display (Fig. 9) shows the actual sampled waveform in the digital processing units
on a reference graticule. The Properties dialog remains active and can be used to change MCB
settings while you are viewing the pulses.
As none of the traditional analog signals are available in the digiBASE, this mode is the only
way to display the equivalent amplifier output pulse. Note that at the bottom of the window the
marker channel is displayed in units of time.
Exiting InSight Mode
To exit the InSight mode and return to the PHA display, press
<Esc>
or go to the
Insight
section
on the Amplifier 2 tab and click
Stop
. The PHA mode is set to STOP when you enter the InSight
mode.
InSight Controls
The Status Sidebar changes from the PHA mode controls to the InSight controls for adjusting
the peak display. On the left is a vertical scrollbar for adjusting the vertical offset of the wave-
form. The value of the offset is shown on the display. Double-clicking the mouse in the scrollbar
will set the vertical offset to the vertical value of the channel at the marker position. This lets
you conveniently zoom in on a particular part of the waveform.
In the
Auto
trigger mode, the display is updated every time a new pulse exceeds the trigger
level. To keep a single pulse displayed, select
Single
. Click
Reset
to refresh the display to see
the next pulse. There will usually be one or two pulses in the “pipeline” that will be displayed
before any change entered will be seen. If the trigger is turned off, the display will be redrawn
periodically, even if no pulse is there.
Just as for the PHA mode display, the vertical scale can be adjusted with the vertical adjust-
ments. The display can be set to
Log
mode, but the peak shapes do not have a familiar shape in
this display. The
Auto
mode will adjust the vertical scale for each pulse. The pulse is shown
before the amplifier gain has been applied, so the relation between channel number and pulse
height is not fixed.
The horizontal scale extends from 16 to 256 channels. The display is expanded around the
marker position which means that in some cases the peak will disappear from the display when it
is expanded.
