Description

The Model 2022 Spectroscopy Amplifier offers excellent resolution performance in a low cost, single width NIM module. CANBERRA's well known filter shaping provides improved pulse symmetry, minimum sensitivity of output amplitude to variations in detector rise time, and maximum signal to noise ratio. Unipolar shaping is achieved with one differentiator and two active filter integrators. The differentiator is placed early in the amplifier to insure good overload recovery. The integrators are placed late to minimize noise contribution from the gain stages. The amplifier offers six front panel selectable pulse shaping time constants: 0.5, 1, 2, 4, 8 and 12 µs.

The Model 2022 employs CANBERRA's unique baseline restorer for optimum performance with high resolution detector systems. The gated baseline restorer automatically adjusts the restoration rate and threshold optimizing performance to the incoming count rate and system noise level.

Simultaneous unipolar and bipolar outputs are available at both front and rear panel BNC connectors. The unipolar signal is used for spectral analysis. The bipolar output can be used for counting, timing, or gating.

The Model 2022 solid dc stability and low noise to provide a high performance spectroscopy amplifier in a single width NIM module.
