Dual Delay

Features

  • Delay from 0 to 63.5 ns (+ 1.6 ns offset) per section

  • ±100 ps accuracy on 0.5 to 8 ns delay lines, ±200 ps on higher lines
  • VSWR < 1.15

Overview

The CAEN Mod. N108A is a passive dual section delay unit housed in a single unit NIM module; the module does not require any power supply since it is made up of calibrated coaxial cable stubs for high accuracy delay. Delay ranges from 0 to 63.5 ns for each section (0.5 ns steps). Each section has a 1.6 ns offset, so the actual delay ranges from 1.6 ns to 65.1 ns. In order to add a delay, the relevant toggle switch must be pulled towards right.
The delay sections (called “A” and “B”) are provided with two LEMO 00 connectors each, which are bi-directional: each connector can be used either as input or as output. Input impedance is 50 Ohm. Seven toggle switches per section allow the delay setting.
