The Frontline X240 Wireless Protocol Analyzer captures information streaming between wireless devices and can do so utilizing various technologies including Bluetooth, Wi-Fi, and 802.15.4. It is paired with the powerful Teledyne LeCroy Wireless Protocol Suite software to provide developers with a robust set of analysis tools including Bluetooth protocol analysis, Bluetooth audio analysis, and spectrum analysis.

The Frontline X240 makes it possible to capture and decode the wireless devices being developed or debugged in even the most challenging settings. It is compact, powerful, and built for mobility - weighing only 1.5 lbs! It can capture up to 16 logic channels and it can be powered by USB, enabling Excursion Mode for PC-free captures. It is great for use in the lab or test facility, but fantastic when you need to get mobile and take it with you in field or on the road.

  • Faster root cause analysis on Bluetooth protocol and audio issues with the included Bluetooth Audio Expert System
  • Manual and automatic gain controls for easy adaptations to every environment
  • Live or post-capture decryption and analysis
  • All Bluetooth profiles and protocols supported through the latest specification
  • Excursion Mode allows for one-button PC-free captures
  • Spectrum analysis helps identify potential RF conflicts
  • Support for Bluetooth mesh technology
  • Wired capture via two highly user-configurable 8-channel HCI UART/Logic Pods
  • Capture and decode HCI UART (H4, H5, BCSP, and WCI-2)
  • Integration into automation setup using extensive APIs

The Right Tool For Every Job

With the Frontline X240, a new a la carte licensing model allows the user to create the right tool for every job. Equip the X240 with any single technology (Bluetooth BR/ EDR, Bluetooth LE, Bluetooth Dual-Mode, 802.11 a/b/g/n and ac, or 802.15.4) or any combination of those technologies for a tool that's no less than exactly what you need, and no more than you need to buy. CrossSync™ functionality allows you to connect multiple X240 units together to capture multiple technologies simultaneously, and facilitates antenna diversity.

Maximum Mobility

Since wireless applications are ubiquitous, the need for mobility during testing is essential. The Frontline X240 was designed with this need in mind. Teledyne LeCroy has packed maximum capturing power in a package that's only a little bigger than a paperback novel. But portability is about more than just size. The Frontline X240 comes equipped with a car adapter for mobile automotive applications, and can be powered by USB when AC power is hard to come by. And when true mobility is called for, Excursion Mode will allow the user to capture everything in the air at the push of a button, without any PC attached.

  • Compact format (7.5” wide X 4" deep X 1" tall) - only 1.5 lbs
  • Select your devices to focus on and your piconets and topologies
  • Single click to start capturing data
  • Decrypt and analyze data DURING or AFTER capture - live and post-capture decryption

Spectrum Analysis

The Frontline X240 Spectrum Analysis feature provides an RF heat map of the entire 2.4GHz ISM Band in Wireless Protocol Suite software. This enables the user to view time-synced captured wireless packets overlaid on top of the captured RF energy within the test environment. Signal strength (RSSI) is displayed when the user hovers over captured RF energy. With this data you can see how multiple technologies coexist in the Coexistence view.

The Spectrum Analysis feature and Coexistence view enables the user to identify RF interference and understand how their wireless devices operate effectively in the crowded 2.4GHz ISM band.

Wireless Protocol Suite

Teledyne LeCroy’s Wireless Protocol Suite combines Frontline’s decades of protocol analysis experience and up-to-the moment spec support with a streamlined interface, bringing all analysis tools into a single dockable framework that can be customized to your own preferred way of working and evaluating information. When paired with Teledyne LeCroy’s uniquely portable and configurable family of wireless protocol analyzers, the Wireless Protocol Suite delivers a world class software experience to anyone working with technologies that utilize the 2.4GHz ISM band.
