Amptek PX4 是用于XR100系列探测器和计算机之间的接口，并附带数据采集、控制和分析软件。PX4包括以下部件：
的脉冲整形放大器
多道分析器
电源
主要特点： | 低功耗: 通常2 W |
| 体积小: 6.5 x 5.5 x 1.5 inches (165 x 135 x 40 mm) |
| 重量轻: 1.6 lbs/750 g |
| 偏置高压100V到1.5KV可调 |
| 带负反馈的电子制冷器 |
| 输入电压+5V直流 |
| USB接口 |
| 高达8K MCA通道 |
| 8个单通道输出 |
| 增益设定 | 28 个用户可选粗调增益设置，从x4 到 x560. 细调增益范围从 0.75 到 1.25. |
| 脉冲成型 | Trapezoidal. A semi-gaussian amplifier with shaping time t has a peaking time of 2.2t and is comparable in performance with the trapezoidal shape of the same peaking time. |
| Peaking and Flat Top Times | Twenty-four programmable peaking times between 0.8 and 102 µsec. For each peak time, sixteen flat top durations are available, > 0.2 µsec |
| Rise Time Discriminator (RTD) | The digital pulse processor can be programmed to select input pulses based on their rise time properties. |
| Throughput | The pulse processing electronics have a cycle time of 1 µsec. With a peaking time of 0.8 µsec, a 1MHz periodic signal can be acquired. Dead time is 1.25 x peaking time. |
| Pile-Up Reject | Pulses separated by more than the fast channel resolving time, 600 nsec, and less than 1.25 x peaking time are rejected. |
| Number of channels | Commandable to 256, 512, 1k, 2k, 4k, or 8k channels. |
| Analog Input (BNC) | The analog input accepts pulses from the XR100 or any other detector with preamplifier reset or resistive feedback. |
| XR100 Power (6 pin LEMO) | Provides power to preamp and detector. Includes HV bias, thermoelectric cooler power, and preamp power. |
| USB and RS-232 Serial Interface | Standard USB 1.1 (USB 2.0 compatible) and RS-232 interface to personal computer. Used for data acquisition and hardware control. |
| DAC Output (BNC) | This output is used in oscilloscope mode, to view the shaped pulse and other diagnostic signals. Range: 0 to 1 V. |
| Input Power | 5 VDC (500 mA max) via power jack. It mates with a center positive 5.5 mm x 2.1 mm Power Plug. |
