2.5.1. Amplifier
Figure 7 shows the Amplifier tab.
This tab contains the controls for
Gain and Shaping Time .
Set the amplifier coarse gain by
setting the gain jumper described
in Section 2.2 to 1×, 3×, or 9× (be
sure to note the setting; it is not
reflected in this dialog). Then ad-
just the
Fine gain with the hori-
zontal slider bar or the edit box,
in the range of 0.4 to 1.2. The two
controls used together cover the
entire range of amplification
from 0.4 to 10.8.
In almost all cases, the default Shaping Time , 0.75 ì s, is the preferred setting. However, the
digiBASE supports shaping times from 0.75 ì s to 2 ì s in steps of 0.25 ì s.
2.5.2. Amplifier 2
Figure 8 shows the Amplifier 2
tab, which accesses the InSight™
Virtual Oscilloscope mode. For the
more advanced user, the InSight
mode allows you to directly the
digiBASE’s advanced shaping
parameters and adjust them inter-
actively while collecting live data.
To access the InSight mode, click
Start , then refer to the discussion
in Section 2.5.2.1.
When you are satisfied with the
settings,
Close
the Properties
dialog and prepare to acquire data.
Once data acquisition is underway,
the advanced user might wish to return to
this tab and switch to the Insight mode to monitor or adjust the shaping parameters interactively
with a “live” waveform showing the actual pulse shape.
