Installation procedure
2.5.4 Measuring a typical Pre-Amplifier Signal
We will now use the MCA4A's internal test pulser to produce pre-amplifier like input signals and setup the
pole zero filter and the trapezoidal shaper.
Since most pre-amplifier signals are typically negative we switch to the negative unipolar pulse polarity and
use the scope mode to see how the input signals look like. In the ADC Settings dialog select
Neg. unipolar,
set PHA
to
Maximum
and
Scope-Mode
with
Falling edge
trigger. Then setup the Shaper with
Software
(ref.
Fig. 2.19).
When clicking into the
Testpulser..
checkbox a Test pulser setup window opens. Setup the pulser with a fast
rise time of "2", a long fall time of "200", an amplitude setting of "50" and a period of "5" x 32.8µs as in Fig.
2.20.
