General Description
N-TM 503B 100MHz CLOCK GENERATOR is the module that has the pulse generator(100MHz) and prescaler.The pulse generator part is composed of the output (FAST NIM) that produces 100MHz pulse generator and 12 positions of frequency (10Hz, 500Hz, 1KHz, 5KHz, 10KHz, 50KHz, 100KHz, 500KHz, 1MHz, 5MHz, 10MHz). This 12 positions of frequency selected by the rotary switch. This output is FAST NIM and TTL signal (50Ω driver).Also, the pulse is able to adjust output width.The prescaler part has the preset counter of 8bit.This function is divided by the setting of the DIP switch(256 step).The input is selected INT.(300MHz) and EXT. by the toggle switch.The input frequency of EXT. IN is maximum 500MHz (FAST NIM).This output pulse (FAST NIM) is able to adjust width.
