NIC-500X for pulseEKKO transmitters & receivers

NIC-500X for pulseEKKO®

The NIC-500X provides the most advanced functionality and connects any combination of pulseEKKO transmitters and receivers up to a total of 8.

• A NIC-500X will run any combination of pulseEKKO transmitters and receivers up to a total of 8
• Supports concurrent receiver data collection – multiple receivers can “listen” to one transmitter fire – true multi-fold data collection and seismic-style data processing.
• Supports sequencing of transmitters and receivers: Transmitters and receivers can be sequenced in any order of firing and listening and are not limited to set transmitter and receiver pairs.
• SPIDAR software allows for the flexible configuration of concurrent or sequenced data collection

Example NIC-500X Configurations

Multi-fold System – WARR Machine

The NIC-500X allows one pulseEKKO transmitter to fire to up to 7 receivers. This is known as a WARR-Machine (Wide Angle Reflection & Refraction) and provides seismic-like, multi-fold data collection.
This example shows a 7-fold data collection.

This example shows a 7-fold data collection.

Note that WARR-Machines can be made from any pulseEKKO frequency: 12.5, 25, 50, 100, 200, 250, 500 or 1000 MHz.

Cross-Polarization System

Array Systems:

With the NIC-500X’s sequencing ability, one pulseEKKO transmitter can fire and be received by two or more pulseEKKO receivers. This allows the assembly of compact multi-channel systems.

These examples show 7-channel, 500 MHz and 100 MHz arrays but any antenna frequency (12.5, 25, 50, 100, 200, 250, 500 or 1000 MHz) can be assembled for a wide variety of GPR applications.

Transillumination Systems

Transillumination surveys differ from the more commonly performed reflection GPR surveys by the fact that the GPR energy only travels one-way between the transmitter and receiver. Conceptually, this type of survey is like medical imaging, such as a CT scan.

The NIC-500X’s ability to collect concurrent and sequenced data makes it a natural choice for the collection of GPR transillumination data.

With transillumination, the GPR signal travel time measurements between every Tx-Rx pair is processed into a GPR velocity image. Another material property that can be imaged using transillumination data is the attenuation of the GPR signal amplitude.

Note that any GPR frequency from 12.5 to 1000 MHz can be used, mostly dependent on the scale of the structure being scanned, from small concrete structures to large earth dams.

Multi-frequency pulseEKKO Systems

The NIC-500X supports a maximum of 4 pulseEKKO systems. The example below shows 4 systems from 100 to 500 MHz, but 12.5, 25, 50 and 1000 MHz can also be included.
