1.2 Channel Input Specifications
Bandwidth and Rise Time
The bandwidth specification indicates the frequency at which an input signal will be attenuated by 3 dB
(approximately 30 % loss of amplitude).
The U5310A ADC card offers a 2 GHz bandwidth limiter -also see
bandwidth limiter? (page
The bandwidth also has an impact on the minimum rise and fall times that can be passed through the
front-end electronics. A pulse with a very sharp edge will be observed to have a minimum rise timeT
determined by the front-end electronics. In general a pulse with a given 10-90% rise time T
be observed with a lower value given by:

Using Bandwidth Limiter
U5310A ADC cards offer a 2 GHz bandwidth limiter capability (Specified with default mode
"Equalization Off").
Also see Programing section
When using the bandwidth limiter, it is recommended to use the default equalization mode
(Equalization off).
Vertical Resolution
The U5310A ADC Card uses 10-bit ADCs giving 1024 levels at each input full scale range.
