タイトルまたは説明

GammaSpectrum*1 Multichannel Analyzer picture as shown in figure 2.The performance indicators are as follows:

• Maximum throughput: >**0kcps;
• Coarse gain: 1,2,4,8,*6 or *2 ;
• Fine gain: 0.*5 ~ 1 ;
• Maximum channel: ****4
• The shaping time constant:

• Linearity:

• System Temperature Coefficient:  Gain: <*5 ppm/°C. Offset <*0 ppm/°C.ï¼›
• Overload Recovery: At maximum gain, recovers to within 2% of rated output from ×***0 overload in 2.5 non-overloaded pulse widths;
• Pulse Pile Up Rejecter: Automatically set threshold. Pulse-Pair Resolution typically **0 ns;
