SCPI commands:

SYStem:BIAS <INT>

Set the SiPM bias, given in [mV]. Higher bias means a higher signal amplification. If a very low bias is set it might be impossible to digitize the signals. It is not possible to choose a bias that damages the system if the enclosure is intact.

Maximum = 29950 mV Minimum = 24304 mV Default = ?

Example: SYS:BIAS 26000 (Sets the bias to 26.00V).

SYStem:BIAS?

Returns: SiPM bias in mV [INT]

SYStem:ATC <BOOL>

Activates or deactivates the **A**utomatic **T**emperature **C**ompensation. If enabled the bias of the SiPM is automatically adjusted to achieve a constant gain during temperature variations. It is very recommended to acctivate the ATC during measurements.

Default = ?

Example: SYS:ATC ON (Activates the ATC).

SYStem:ATC?

Returns: State of the ATC [BOOL]

SYStem:TEMPerature?

Returns: SiPM temperature in mC [INT]

SYStem:COMPerator:THReshold <INT>

Set the comperator threshold for the external and internal channel. The number is given in DAC counts. Higher numbers mean a higher signal level that is needed to trigger a detection of a pulse.

Maximum = 4095 Minimum = 0 Default = 0

Example: SYS:COMP:THR 100
