Page 4: Description
Description Description The TA1000B-x comprises a series of fast, very low noise preamplifiers with model dependent voltage gains of 10, 50, 100 or 200 V/V and corresponding small signal bandwidths of 710, 1000, 950 or 400 MHz respectively. A unique feature for such high speed amplifiers is DC coupling. DC coupling avoids count rate effects due to non DC balanced pulse trains and the corresponding charging of coupling capacitors. - Page 5 Description Fig. 1.2: TA1000B-10 simplified schematic Fig. 1.3: TA1000B-50 / -100 / -200 simplified schematic Typical applications for the TA2000B are: Pre-amp for ultra fast detectors (MCP, PMT, …) Oscilloscope and transient recorder pre-amp High precision Time-of-Flight ...

Specifications 2.7. Available options 50 Ohm output impedance This improves the output signal quality since reflections from the target device (oscilloscope, multichannel analyzer, etc.) are well terminated at the TA2000's output and do not travel many times back and force over the cable. Thus, distortion of a subsequent pulse is largely avoided.
