Overview
TR501
The transceiver configuration TR501 has a sampler/transmitter combination together with the switching electronics, this makes possible the use of one antenna in monostatic mode. The signal to noise ratio of the sampler electronics has been optimized for superior performance still retaining a broad bandwidth.

RX501
The receiver configuration RX501 has a single sampler and is meant to be used in conjunction with the very high power transmitter VHT501. In fact, it is the same sampler used in the transceiver configuration.

VHT501
The very high power transmitter VHT501 is designed for very deep survey together with the sampler unit. The power consumption of this unit has been optimized in a way that makes possible to use it with the SIR-3000 radar unit from GSSI without the need of any adaptor (Up to 12 kHz PRF and 30 scans/seconds).

Overview
TR501
The GPR Plug-In Transceiver TR501
The TR501 transceiver is the logical choice if you need a new plug-in transceiver for your existing GSSI compatible antennas or if you are planning to buy new ones. Why?, because it's better, lighter, less expensive, has more functionality and looks nicer than anything else one can find in the market today.
There is no need for extra accessories
The TR501 fits without modifications or amendments into any antenna supporting GSSI compatible plug-in electronics. It gives the possibility of using marker, survey wheel or bistactic mode operation without any extra cost. No need to buy expensive breakout boxes or anything like it in order to use the survey wheel.
Added performance at no extra cost
The TR501 has two separate transmitting channels for each antenna terminal, both are carefully matched by amplitude and phase so the ringing back from your antenna is minimized. There are no late returns causing inexplicable horizontal lines and most importantly there are no dead zones of tens of nanoseconds. The data is sampled using top of the line extra low noise bridges with differential output to the last stage. The unit is calibrated so your competitor won't be getting any better data from our TR501, or any worse for that matter. We guarantee reliability and repeatability of the results, why should one get better or worse data than others if the price is the same? No, of course no reason at all. [Brochure]
User friendly interface is one of the goals
While designing the front panel of the TR501 we put special effort in making all the labels clear and easy to understand. We tried to make the use of the device as intuitive as we could given the space constrains we had. Everybody knows what a radar is and where to connect an output that says external or internal. The handle of the unit is about half an inch higher than in the competitors model, that's to easy the connection of the big radar cable. The RF transmitter loop was made very short, we wanted to avoid it getting stuck in the branches in the forest where some times geophysical surveys also take place.

RX501
The GPR Plug-in receiver RX501
The high performance plug in receiver RX501 is the logical companion for high power transmitters like our VHT501 or the 778 from GSSI Inc. It is designed in a way that it fits into any antenna supporting GSSI compatible plug-in electronics.
One is a lonely number
The high power plug-in transmitters can be used together with the transceiver TR501. Although that is a good solution for many survey situations, the best performance is obtained only when using bistatic antennas and low noise receivers.
In a transceiver configuration the transmitter and the receiver share the same antenna. In that case it is necessary to take measures in order to prevent the saturation or even the destruction of the receiver's sensitive input circuitry. Those measures affect the way the receiver works and at some extend reduce its effective dynamic range.
The best results are achieved using two antennas whenever that is possible. The dual antenna configuration or bistatic mode of operation also allows for other types of surveys not possible in monostatic mode.
Low noise + Low saturation = outstanding results
The fact of having the antennas working in bistatic mode has many advantages. One not so obvious advantage is that the switching circuitry with all the loses accompanying it is not present. That means more of the radio frequency energy reaches the sampling head of the receiver and subsequently more features are available in the radargram.
The output of the transmitter is not any more causing problems saturating the input of the sampler and therefore the so called "dead zone" at the top of the radargram is heavily reduced.
The low noise, higher signal strength and low saturation that can be obtained when using the VHT501 and the RX501 make possible outstanding results and penetration not achieved with monostatic configurations using the transceiver alone.
Extra goodies included
The RX501 has a few extra features that make the decision over similar units in the market even easier. The survey wheel output input and the marker button input are both present as standard. No extra adapters are required to run a survey wheel or to have a GPS adding position coordinates to the collected data.

VHT501
The GPR Plug-In High Power Transmitter VHT501
The high power plug in transmitter VHT501 is the most affordable and highest quality available device for deep penetration geophysical surveys. It is designed in a way that it fits into any antenna supporting GSSI compatible plug-in electronics.
Bi-static when it's needed
Ground Penetrating Antennas equipped with the TR501 transceiver deliver very clean and low noise data; but sometimes the survey site demands a bit more of penetration in the media or a better top resolution. In that kind of situations a combination of the RX501 receiver and the VHT501 high power transmitter are a saving solution. If from the beginning one doesn't have a RX501 available then a TR501 can be used instead or as a last resort even a GSSI 769DA2 is capable to work together with the VHT501 high power transmitter.
Accessories? No, thanks!
The power consumption of the VHT501 high power transmitter is minimized by a careful and efficient design. That fact allows to use it directly connected to the SIR-3000 radar system with up to 12 kHz and full scan rate. For average geophysical or archeological surveys the VHT501 is ideal because the SIR-3000 won't complain, or beep, or hang with it; it just works and collects the needed data. You won't be needing to buy any break-out box or support unit to operate our VHT501 with a reasonable survey speed and a small and easy to carry radar system.
No slow fall time means no trailing ringing
The VHT501 combines classical approach on high voltage multipliers with state of the art magnetics to deliver clean and well defined pulses. The output pulses have no long fall times causing ringing in the transmitting antennas. The phase unbalance of the VHT501 outputs is below 2.5 degrees guaranteeing low ringing in properly balanced antennas.
User friendly interface is one of the goals
When it was time to design the front interface for the VHT501 high power transmitter we confronted a bit of a dilemma, what connector to use?. We could have used the SMA connector as in our transceiver TR501, as a matter of fact it would have been the logical choice. Then we thought that some of our customers perhaps don't have a TR501 but a 769DA2 with a BNC connector and that even if they had a TR501 they would need to purchase a trigger cable anyway. At the end we decided to make it easier for our customers and went for a BNC connector. The handle of the unit was chosen so it is easy to connect BNC connector.
