  • Page 5: Introduction

    INTRODUCTION GENERAL DESCRIPTION INTRODUCTION GENERAL DESCRIPTION General The VE 432 is a new generation of Vibrator Digital Control System, using a fully auto- adaptive servomechanism. It enables the use of all advanced Vibroseis techniques such as : - pseudo-random sweeps - multiple simultaneous sources in flip-flop or slip-modes - coded sweeps - cascaded...
  • Page 6 INTRODUCTION GENERAL DESCRIPTION Digital Pilot Generator (DPG) The DPG is connected to the data acquisition system through an Ethernet link and acts as a master control unit for the VE 432 system. The DPG can be : - fully integrated with the SN 388 acquisition system, - or connected to any other type of acquisition system, using its own graphic user interface.
  • Page 7 • • Slip-Sweep* capability With a recording system from SERCEL, there is no need to wait until a sweep is complete to start the next one. (* The Slip-sweep technique, developed by PDO, allows substantial production increase to be achieved).
  • Page 8 INTRODUCTION GENERAL DESCRIPTION • • Recording system’s automatic start of acquisition With a recording system from SERCEL, acquisition by the recording system can be automatically started as soon as the vibrators are ready, using the DSD Ready signal via radio.

  • Page 22: Dpg Master/Slave Configuration

    CONNECTING A DPG DPG Master/Slave configuration DPG Master/Slave configuration It may be desirable to use two recording trucks in parallel, for example because of geographical considerations. One recording truck is used as "Master" and the other as "Slave". Each recording truck is equipped complete with an acquisition system and a DPG. One of the recording trucks is used as "Master"...
  • Page 23 CONNECTING A DPG DPG Master/Slave configuration After the sweep is complete, the Slave DPG sends a status message to the Master DPG which relays it to the SN388 HCI. That status is like those usually returned by DSDs, with an extra specific code (26) if the Slave acquisition system fails to start. That type of error can be detected by monitoring the RDYIN signal, low during acquisition, high otherwise (pins P and R of the RECORDER connector).
