| 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. |
