DESCRIPTION
The TA2000B-x models are fast, two-stage pulse pre-amplifier with a small signal bandwidth of 1.5 … 2.0 GHz depending on the model.
A unique feature for such high speed amplifiers is the DC coupling. DC coupling avoids count rate effects due to non DC balanced pulse trains and the corresponding charging of coupling capacitors.
