GENERAL DESCRIPTION
C-RL 207 NON STOP TDC（Time to Digital Converter）measures time interval of between each events continuously.The resolution of measuring time can be set up with CAMAC function.The conversion starts when RUN input (TTL) signal changes ‘L’to’H’,and a converted time data is continuously transformed into 16 bits memory when RUN is ‘H’level.

SPECIFICATIONS
＊NUMBER OF CHANNEL ： 2
＊RUN INPUT : TTL At the time of ‘H’ measurement possibility At the time of ‘L’ during waiting
＊EVENT INPUT : signal NIM (MIN. pulse width 20ns)
＊TIME ACCURACY : Setting by the timer registration
t = N×10^n (μs)
N = 1～15 (W5-8)
n = 0～7 (W1-4)
＊TRANSFORMATION DATA : 16 bit (R1～R16)
＊POWER SUPPLY : -6V=0.1A , +6V=0.5A

CAMAC FUNCTION

N・F(2)・A(0) ： data registration read & restart
N・F(8)・A(0) ： test LAM
N・F(10)・A(0) ： clear LAM
N・F(16)・A(0) ： timer registration write
N・F(24)・A(0) ： disable　LAM
N・F(26)・A(0) ： enable LAM
