current Subject:
In which level should the signals I use range, which I feed to the inputs of the measuring cards?
Please refer first and foremost to our information in the User Guide for the respective product. The following technical specifications are subject to change without notice.
- Our standard TDCs are AC coupled. The DC base line can be between 0V and 5V for these devices. Short positive and negative pulses with an amplitude of up to 5V can be processed. The discriminator threshold can be set between -1.32V and 1.18V relative to the DC baseline, with a step size of 40 µV. In general, the threshold voltage should be set well above the noise level of the input signal.
- The inputs of our standard ADCs are AC-coupled single-ended analog inputs. The maximum input voltage is 0.5 V (Ndigo5G-10) or 1 V (Ndigo6G-12) and the input impedance is 50 Ω. The analog offset can be between -0.25 and +0.25 V (Ndigo5G-10) or -0.5 and +0.5 V (Ndigo6G-12).
