For MASW Projects


	12 or 24 channel Streamers
	The "MASW" version of the DAQlink 4 is configured for small projects. It is well-suited for programs requiring 12 or 24 channels and short shot records. Like MASW projects, for example.
	The MASW DAQlink features:
	12 or 24 channels
	Records up 32,000 in length
	Samples rates up to 2000 SPS
	Plus, all the industry-leading specifications of the standard DAQlink 4
	The MASW DAQlink suitable for:
	MASW Data
	Reflection Data
	Acquiring data with a land or marine streamer
	Any project requiring high-quality seismic data
	The MASW DAQlink:
	Has a solid all-aluminum case
	Is small and lightweight
	Is also frugal with power, will use any type of 12V battery
	Can be powered via vehicle during streamer operation
	Is compatible with the WTB 4 radio trigger system

Distributed DAQlink for Larger Projects

The Distributed DAQlink 4 System adds the ability to reliably connect multiple DAQlinks into a network.

	The Distributed DAQlink:
	Contains local and remote network extenders inside the case for reliable connections
	Individual network cable links can reach 10,000 ft, or 3 km
	Using inexpensive twisted pair telephone cable, or spread cables with imbedded communications
	Networking cables also send trigger signals to the rest of the DAQlinks for reliable triggering
	Networking cables send commands from the computer to the DAQlinks and return seismic data from them
	Over 20 DAQlink 4’s can be networked for systems with hundreds of channels
	The field computer controls the seismograph network, provides quality control for the data, and stores the shot records all in real time

MegaDAQ

240 channel system shown

	MegaDAQ Features:
	All connectors have been relocated to the side of the case, enabling DAQlinks to be stacked
	With the connectors centralized, cable runs are shorter and easier to maintain
	With the seismograph modules in a central location, they can be networked for real-time data
	MegaDAQ configurations utilize a single GPS module for consistent timing
	The MegaDAQ configuration packs the largest number of channels into the minimum amount of space

Acquisition Software Options

BGR

	BGR
	BGR is a single screen, basic data acquisition program. It is typically employ for single person crews, or for automated acquisition. All acquisition parameters are available on the single screen, including channel selection and directory. BGR comfortably runs several seismographs, and can handle different types of seismographs simultaneously.

Vscope3

	Vscope 3
	Use the SSC Land Streamer with the DAQlink for rapid data acquisition. Deploy the spread cable at the beginning of the line, and then quickly move it for the next shot. Especially useful for MASW projects.

Observer

	Observer
	All DAQlink 4 seismographs are compatible with the entire line of Seismic Source Co source control electronics. This includes the Force 3 Vibroseis controller, the Boom Box 3 dynamite synchronizer and the RTM 3 remote trigger module. DAQlink seismographs are also compatible with the Universal Encoder 3, use it for precise source operation.

Expandability and Flexibility

wtb4

	Wireless Trigger Box 4
	The WTB 4 removes the cable between the source and the seismograph, plus the frustration of dragging the firing line through the brush and around other obstacles.
