Page 5: Introduction
1.0 Introduction The PPS-2RM-B is a dual 1 pulse-per-second (1 PPS) generator. This instrument requires a sine-wave input signal of 1 MHz, 5 MHz or 10 MHz to generate the 1 PPS. The PPS-2RM-B generates two pairs of independent 1 pulse-per-second outputs with variable pulse width. -
Page 6: Safety And Preparation For Use
The switching from AC to DC supply operation is affected by a Schottky diode network and charge storage capacitors to ensure glitch free operation. If the PPS-2RM-B was acquired with the DC operation option a 6 pin DC connector will be available on the back panel. - Page 7 Detaching the DC power cord is the only option of disconnecting the unit from the DC mains supply. Make sure you have access to the rear panel or provide an external accessible DC disconnect means for your PPS-2RM-B. Page 3...
