Mini Trace II
Timeless and reliable dual-channel very high (24-bit) seismic data recorder.
MINI-TRACE II DUAL ACQUISITION MODULE
The new Mini-Trace II acquisition module is a very high resolution, 24-bit sigma-delta, seismic recorder, which can be interfaced to any suitable laptop or desktop computer, using a plug-and-play USB connection.
Navigation data is acquired via the LAN of the control PC or via a serial port on the acquisition module (for old systems).
TIMELESS AND RELIABLE HARDWARE
The Mini-Trace II is timeless and will serve you a long time. It features extremely reliable hardware with fully integrated electronics, which will outlast by many years the typical life time of the control computer.
DUAL MODE PROGRAMMABLE TRIGGERS
The module contains two independent channels with two independently programmable triggers allowing to synchronize two sources without interference ( Asynchronous mode)
In asynchrounous mode: sparker + pinger, or sparker +water gun, but also sparker + side scan can be triggered in such a way that you will see no interference of the Sparker signal on the SSS data.
All raw data files are recorded in Standard SEG Y format, with samples encoded in integers and can also exported in XTF format (16 bit). In addition, extensive logging in text files of all acquisition events, manual fixes, raw and processed navigation data.
INPUTS AND OUTPUTS
The unit has two independent channels, each with an differential input ranging between
+5 V and -5 V. The 24-bit sigma-delta A/D converter provides a 112 dB of dynamic range. This range eliminates the need to calibrate the AD converter for the incoming signal strength, thereby simplifying setup procedures, while retaining high data quality.
Each channel has its own trigger input which is can be used for the slave mode. For instance with an external trigger from navigation for shooting at fixed distance. Standard TTL input via BNC at the rear. Accepts trigger pulse from 4 V up to 12 V, 10 mA, with a pulse length of 1 ms.
Each channel has its own trigger output which is can be used for the master mode, normally used to trigger the source in time. Standard TTL output via BNC at the rear.
The two triggers are fully programmable, including all options to set delays, time-breaks,
differential triggering and custom triggering patterns.
Navigation input is available via PC serial ports, LAN Network or Mini-Trace II dedicated serial port. The acquisition software supports NMEA data format or any other proprietary format navigation, fix and annotation strings.
All data are logged and accessible in separate log files.
Simultaneous display of the navigation map, multiple data channels and data types in
multiple windows, on single or dual monitors.
CUSTOMIZABLE WINDOW LAYOUTS
ser-defined windows, Profile, Raw Trace, Processed Trace, Spectrum Analysis, Real-time Navigation track plot window, left/right, up/down, scroll directions.
Real-time navigation annotation on screen is standard, dedicated window for real time track plot, navigation editing, smoothing, speed correction etc.
EFFICIENT ONLINE QUALITY CONTROL
The new status monitor makes recording of very high quality seismic data very easy. It tells you all you need to know about the dynamic range in use. The software also analyses your settings and warns you for any problems, which might occur in your recording.
REAL-TIME NAVIGATION MAP
The navigation map is displayed in real-time showing your current position and route. You can combine it with any geo-referenced background e.g. from Google Earth. You can also use public domain data from hydrographic data bases. To generate a track plot of the seismic lines is just one click of the mouse.
SEAMLESS INTEGRATION WITH GEOSUITE ALLWORKS
GeoSuite Acquisition software outputs the raw data as a standard SEG-Y file, which is seamlessly imported into Geo-Suite AllWorks. Alternative you export the data in XTF format for import in any other third party environment.
