Mini Trace II

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.

TRIGGER INPUTS

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.

TRIGGER OUTPUTS

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.

PROGRAMMABLE TRIGGERS

The two triggers are fully programmable, including all options to set delays, time-breaks,

differential triggering and custom triggering patterns.

NAVIGATION

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.

MULTIPLE SCREENS

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.

NAVIGATION TRACK-PLOTS

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.
