The Mod. N470 is a double width
NIM unit housing 4 independent High Voltage channels.
The output
voltage ranges of each channel are the following:
- from 0 to ±3
kV / 3 mA;
- from ±3 kV to ±4 kV / 2 mA;
- from ±4 kV to ±8 kV / 1
mA.
The range selection is automatic, as the output voltage is
set. The current resolution is 1 µA.
The output polarity is
independently selectable for each channel.
It is possible on each
channel to control several operating parameters: two levels of presettable
high voltage, two levels of current limit, Ramp-up, Ramp-down. All these
parameters can be programmed and monitored either in remote mode, via HIGH
SPEED CAENET (either using the V288 VME controller or the A1303 PCI Bus
controller), or in local mode, via front panel alphanumeric keypad and two
8-character displays. In addition some LEDs display the status of the
selected channel.
All the functional parameters are stored in a
non-volatile memory.
Front panel trimmers allow the setting of maximum
voltage limits, and the two current and voltage limits can be selected via
two external NIM/TTL signals. A NIM/TTL signal is also available for the
KILL function, as well as a complete calibration menu.
The High
Voltage output is provided by female SHV connectors.
