Phoenix - Model MTU Series -Ultra-Wideband MT Receiver Systems

Phoenix Geophysics designs advanced ultra-wideband magnetotelluric (MT) receiver systems, including the MTU-5C, MTU-8A, and RXU-8A models. These receivers are engineered to operate in harsh field conditions, providing reliable geophysical data collection. They integrate seamlessly with Phoenix sensors and the EMPower software, offering efficient and intuitive setups. With nearly five decades of experience, Phoenix has optimized these devices for high performance and simplicity. The built-in bright screen on Phoenix receivers enables real-time monitoring without needing additional devices. These systems feature automatic diagnostics, in-field calibration, and comprehensive metadata logging. Configuring the receivers is streamlined through SD card setup and EMPower`s Config Creator. They support up to eight independent channels with flexible settings, accommodating both recent and older sensor models.

Designed in Canada, Ready for the World

Built to work with Phoenix sensors and EMPower software, next-generation MTU-5C, MTU-8A, and RXU-8A receivers are designed to survive life in the field and provide excellent geophysical results.

Nearly 50 years of equipment design and field experience come together at Phoenix to make our receiver systems high-performance, simple, and rugged– doing their job so you can do yours, wherever you need to go.

Quality Control Built-In

The bright, built-in colour screen on every Phoenix receiver shows every user what’s going on right in the field, without needing any other device to make sure everything is connected, ready, and working.

Automatic system and recording diagnostics, in-field calibration capability, and extensive metadata ensure proper logging of system performance and field operations.

Easy Configuration and Easy Operation

Configuration files on the SD card set every receiver parameter, from decimation rates to filter settings. Making new config files takes just seconds using EMPower’s visual Config Creator.

Single-button start means field operators can focus on field operations, not data entry, helping to avoid mistakes and keep crews moving.

Up to 8 independent channels with their own gain, filter, and sensor type settings provide maximum flexibility, and with no adaptors or separate sensor power supplies required, equipment layout is intuitive and clear.

Fluxgates Supported

MTU-5C, MTU-8A and RXU-8A work directly with Bartington Mag13-MS70, Bartington Mag03MSES70, and LEMI-039 fluxgate sensors, enabling more efficient long-period measurements. EMpower also supports configuring these fluxgates and correctly processing their results.

Connected Everywhere

With built-in ethernet networking and simple network configuration, every Phoenix receiver can upload data to a remote server by cellular or satellite modem. Want remote station data at the base camp before heading to the site in the morning? Phoenix systems let you do that.

In a fully-connected survey, all data quality decisions can be made –and made with the benefit of remote reference processing– before a crew even goes out to the field in the morning, improving QC, reducing unnecessary repeats, and eliminating data transfer and evaluation by the operating crew.

Once uploaded, the time series can be immediately and securely shared with clients, consultants, and geoscientists back at the office for review, planning and backup.

Powerful and Power Efficient

Phoenix receivers offer selectable data sampling rates from full-rate 24ksps recording that generates about 1GB/hour all the way down to sparse high frequency sampling outputting 10MB/hour (0.01GB/hr), with typical settings generating about 1GB of data per overnight 5-component recording.

This allows users the option of full-rate recording to capture every high frequency event during the acquisition time, or optional progressive levels of sparse sampling decimation to reduce file sizes and data transfer requirements.

At about 1 Watt per channel, Phoenix receivers are the most power-efficient true broadband systems available. Able to run for days on a normal car battery, they also allow inputs from 10.8V to 14V, making it easy to use more modern batteries.

Massive Storage

With standard 64GB of removable storage and support for up to 512GB SD cards, Phoenix receivers are able to record more than 500 days of normal 5-channel MT timeseries, and 2000 days using the long-term sparse sampling mode.

Incredibly rugged and reliable, SD cards are rated to –25C / 85C, shock and impact resistant, waterproof, and x-ray proof. They are also highly compatible, fast, and supported card types are readily available at reasonable cost.
