DUAL TIMER - mod 2255B

该插件由两组完全相同的触发脉冲产生器组成。可用来调节 NIM 及 ECL 信号的宽度从 50 ns 到 10 s。

The END-MARKER, a short output pulse at the end of the tiiming cycle, can be uesd for delayed triggering of other units or, if fed back into the START input, it provides a self-running rate generator that can be started and stopped at will.

It is possible to disable start inputs by feeding a NIM signal to the "Veto" input.

输入

• START INPUT
  • NIM and ECL,leading edge sensitive.
  • Minimum width 5 ns.
  • Momentary switch for single cycle operation.
• VETO INPUT
  • NIM input
  • NUM ture level at VETO input desables the START input (within +-2ns of START leading edge)
• RESET INPUT
  • NIM input
  • Minimum width: 7 ns (15 ns for recursive operation)
  • It can be applied at any point of the time cycle.
  • Produces END-MARKER

输出

• OUTPUTS
  • Two normal independent,one complementary NIM output and one ECL.
• WIDTH
  • 50 ns to 10 s in 9 decade steps, with a potentiometer and locking dial for fine adjustment
  • Accuracy +-10% of full scale, with adequate range overlap.
  • Temperature coefficient: 10^{-3}/^{0}C of setting
  • Switch postion <<无穷>> for bistable opreation
• DEAD TIME
  • Shorter than the cycle time
  • The timer can be triggered well before the ehd of the timing cucle.
• RISE/FALL TIME
  • <= 2 ns
• INPUT-OUTPUT DELAY
  • Delay from Start to leading edge of output,or from Reset to trailing edge,is ~13 ns
• END MARKER
  • NIM and ECL output, 15 ns wide output pulse leading edge is coincident with the trailing edge of output within 2 ns.
  • Can be connected to Start input for free running opreation (sequence activated by the START switch)
• LED
  • Flashes for 0.1 s or output width, whichever is longer.
  • At high rates the lamp has its own flashing rate.
