3. OPERATING MODES

3.1 GENERAL

INFORMATION

The Model N 568B/LC is a 16 CHANNEL SPECTROSCOPY AMPLIFIER implemented in a single-
width NIM module.

Thanks to its high channel density, this unit allows the optimization of cost and size in multi-detector
systems.

3.2 MODULE

OPERATION

At Power-ON, the module contains the last performed settings before Power-Off. The status of these
settings can be read out via H.S. CAENET (see below).

The settings on each channel of the module can be performed in any order. Due to the logical
dependence of certain settings from others, it is anyhow suggested to perform the first time User'
settings on each channel of the module in the following order:

a) set the output configuration (non-inverting or inverting);
b) set the output polarity (positive or negative);
c) set the shape;
d) set the coarse gain;
e) set the fine gain;
f) set the pole-zero adjustment;
g) set the offset;
h) enable or disable the multiplexed output.

Once performed either first-time or ordinary settings, it is suggested, for best noise performances,
NOT to access the module frequently via H.S. CAENET (e.g. for monitoring) while the module is
operating on the final experimental setup.

The following paragraphs describe in more detail the single settings. Offset, Fine Gain and Pole-zero
settings must be thought not as absolute settings, but as "digital trimmers" with which the User sets
the desired parameters and controls the outputs obtained with well-known pulse shapes.

3.2.1 MANUAL

SETTINGS

A two-digit thumb-wheel switch selects the module's Station Number for the CAENET operations.

3.2.2 OUTPUT CONFIGURATION SETTING

The OUT and XOUT configuration settings can be performed either via Manual Controller or via H. S.
CAENET. They allow to select between DIRECT (NON-INVERTED) or INVERTED outputs. The
FOUT configuration can be selected between DIRECT (NON-INVERTED, factory setting) or
