數位多通道分析儀

Amptek 的 MCA-8000D 是一款先進、輕巧、高性能的數位多通道分析儀（MCA）。 它取代了 MCA-8000A，可提供相同的功能，但具有更少的死區時間、現代化的通信介面（USB、RS-232 和乙太網路）以及更高的數據傳輸速率。 由於它不進行數位脈衝整形，因此它與類比脈衝整形系統相容。
高速 ADC（100 MHz 16 bit ADC）和精密的數位邏輯提供了卓越的性能。 MCA-8000D 將輸入信號（類比整形放大器的輸出）數位化，以測量脈衝高度並獲得脈衝高度頻譜。 具有 10 ns 轉換時間的高速 ADC 減少了死區時間，從而提高了傳遞量。 數位電路提供了高精度和穩定性。
MCA-8000D 包括三個介面：USB（全速 USB 2.0）、RS-232（高達 115 kB）和乙太網路（10base-T）。 它使用與 Amptek DP5、PX5 和 X-123 等數位信號處理器相同的 DPPMCA 軟體版本。 MCA-8000D 可以通過 USB 或外部交流/直流電源供電。
MCA-8000D 是一款高性能、低功耗的輕巧儀器，用途廣泛且使用方便。

機械

Amptek’s MCA-8000D is a state-of-the-art, compact, high performance, digital MultiChannel Analyzer (MCA). It replaces the MCA-8000A, providing the same functionality with reduced dead time, modern communications interfaces (USB, RS-232, and Ethernet), and much higher data transfer rates. Because it does not implement digital pulse shaping, it is compatible with analog pulse shaping systems.

Superior performance is obtained from a high speed ADC (a 100 MHz 16 bit ADC) and sophisticated digital logic. The MCA-8000D digitizes the input signal (the output of an analog shaping amplifier) to measure the pulse height and obtain the pulse height spectrum. The high speed ADC, with a 10 ns conversion time, reduces dead time thus increasing throughput. The digital circuitry yields high accuracy and stability.

The MCA-8000D includes three interfaces, USB (USB 2.0 full speed), RS-232 (up to 115 kB), and Ethernet (10base-T). It uses the same DPPMCA software package as Amptek’s digital signal processors, including the DP5, PX5, and X-123. The MCA-8000D can be powered over USB or with an external AC/DC power supply.
