Phoenix - Model TXU-30 -Multi-Function Geophysical Transmitter

• Compact, portable
• Uses 200–240 V, 50 Hz, 60 Hz, or 400 Hz, 3-phase motor generator
• Permanently synchronized to GPS time ±0.5 µs
• Linear ramp better than 5 µs/ampere (turnoff characteristic for TEM)
• For all common EM geophysical techniques

Simplified MG Requirements

The new design eliminates dependence on specialized motor generators. Now, you can buy or rent a suitable MG from any convenient local supplier, and that means:

• no more service and spare parts supply headaches.
• possible capital cost savings.
• reduced shipping costs. (Over the life of the product, this can add up to considerable savings!)

Advanced Controls - Easy to Use

Advanced microprocessor control provides superior performance across the board. Large, bright LEDs display instrument status and critical values. Simple, straightforward controls make it easy to adjust all operating parameters within allowable limits.

Climate-Controlled Exploration!

Use the cable-linked remote control panel to operate the TXU-30 from up to 30 m away. Manage your EM transmissions in the comfort of a heated or air-conditioned field truck cab! You’ll also appreciate being able to talk with the rest of the crew by mobile phone or radio without having to fight the noise (audible and RFI) of the MG.

High S/N Ratios - Precision Synchronization

In highly resistive areas in the past, users have relied on dangerously high voltages in an attempt to achieve an adequate signal-to-noise ratio at the receiver. The TXU-30`s built-in GPS (Global Positioning System) satellite-synchronized timing control, coupled with companion GPS-synchronized receivers, solves this problem.

Because the entire system is synchronized, receivers can maintain proper registration while stacking even extremely weak signals. The signals can be stacked as long as necessary until the S/N ratio is acceptable.

Wired or Wireless Data Links

The TXU-30 continuously saves time series records of its output current and voltage on a removable 512 MB flash memory card. This information, required for deconvolution calculations in Spectral IP, can be transmitted to a companion receiver system over either a wireless or an optional cable link.

Alternatively, the data on the flash memory card can be uploaded to the post-processing computer via a high-speed, low-cost interface.
