Quantum random number generator
Mean frequency of output pulses can be set by potentiometer P1.
Quantum random number generator
The power supply module can supply up to 500V but its maximum voltage can be restricted through altering a potentiometer.
Characterisation of the VELO High Voltage System
Hence, for safety, this potentiometer will be adjusted to limit the applied voltage.
Characterisation of the VELO High Voltage System
The maxmum voltage and current are adjusted by the potentiometers, labeled Vmax and Imax, next to the two LEMO connectors on the front panel of the module .
Characterisation of the VELO High Voltage System
The potentiometers affect the setting values in the module’s microprocessor.
Characterisation of the VELO High Voltage System
The values set by the potentiometers are converted via an ADC-converter and are processed by this microprocessor.
Characterisation of the VELO High Voltage System
The potentiometer position limits the voltage or current for all channels on the module.
Characterisation of the VELO High Voltage System
It is possible to measure the hardware current or voltage limit that has been set on the potentiometer through the LEMO connector: The maximal value of Imax (4mA) and Vmax (700V) corresponds to 2.5V measured from the LEMO connector.
Characterisation of the VELO High Voltage System
The potentiometer was changed over the full range and thus the voltage measured from the LEMO connector changed accordingly.
Characterisation of the VELO High Voltage System
In addition to the ’hardware’ limit that can be set through the potentiometer, software limits on the current can also be set.
