A: The RTV series is the value series of Talon recorders. These are the least expensive Talon recorders and are intended for laboratory use. They are limited in storage and streaming data rates to disk and have very few options available.

In addition to their low cost, they also have the advantage of shipping from stock, unlike the other series that typically have lead times from six to eight weeks. These recorders come in a rackmountable PC server chassis.

The RTS series is the commercial series of Talon recorders. These are intended for benign environments, have great flexibility in channel count and are capable of holding large volumes of data storage.

These systems use HDDs (hard disk drives) for data storage and are limited in their sustained data rate to disk. These recorders come in a rackmountable PC server chassis.

The RTR series is the rugged series of Talon recorders. RTR recorders come in both a portable (briefcase style) and rackmountable PC server chassis form factor. Both use SSDs (solid state drives) to help the systems tolerate shock and vibration.

They also include enhanced cooling to allow them to operate in higher-temperature environments (up to 55 deg C.) The RTR series recorders provide the highest streaming data rates to disk of all of the Talon series.

The RTX series is the extreme rugged series of Talon recorders. RTX recorders are flight certified, capable of handling high levels of shock and vibration as well as high altitude use.

RTX series chassis use Pentek's QuickPac® drive packaging technology that provides the ability to quickly remove and replace 8 data storage SSDs from the Talon recorder. This is especially useful during flight missions where aircraft time is expensive.

The RTX series chassis comes in two different form factors. A rackmountable chassis uses high-powered fans to air cool system components. This chassis includes a shock-isolated inner chassis, EMI filters, and a modular rear panel to allow for customized signal connectors.

The alternate style RTX chassis focuses on SWaP and is available in a 1/2 ATR style chassis.This conduction-cooled chassis is extremely rugged and is able to operate in the harshest of environments. This chassis uses QuickPac drive packaging technology to provide up to 7.6 TB of storage in a very small package.
