Cobham's 8800SX Offers a New Radio Test Experience
November 29, 2017

With its hybrid portable design, the industry’s largest color touch-screen display, ruggedness, internal battery, power accuracy, advanced automated test and alignment, and fast VSWR/Return Loss and Cable Fault measurements, the 8800SX offers RF professionals a whole new experience in radio test. The 8800SX combines the performance and features of a bench-level test set with the portability and ruggedness of a field-level instrument. Weighing only 17 lbs (7.71 kg), an internal battery with 2.5+ hour of operation, and rugged 30 G shock rating now test professionals will no longer comprise portability for critical test features. Advanced features ranging from automated test and alignment to digital modulation analysis plots to an internal 500 W (4% accuracy) in-line power meter are all available within a one-box solution.

The 8800SX is designed for maximum test efficiency. With the industry’s largest display, ultra-fast store and recall “Presets”, and its unique “Fast-Stack” user interface that allows test tiles to be stacked on one another and quickly accessed, test professionals can set up analog and digital test in seconds and have instant access to more displayed meters and test functions.

With a RF power measurement range from -140 dBm to 500 Watts, the 8800SX is a complete solution for radio system test. Providing both digital radio test capabilities, VSWR and Distance to Fault cable and antenna tests, the 8800SX is ideal for testing P25, P25 Phase 2, DMR, dPMR™, and NXDN™ LMR systems. The 8800SX is designed with advanced frequency, power, and modulation analysis instruments for both analog and digital systems. The channel analyzer offers a unique expanded display mode, which dedicates the entire screen to the analyzer.

The digital test features include:

o   Digital Test Patterns

o   Distribution, Constellation, Eye Diagram Plots

o   TDMA Burst Profile with Mask for DMR and P25 Phase 2

o   Digital Voice Quality Verification

o   Meters, including Signal Power, FSK Error, Magnitude Error, Slot Power, Symbol Deviation, Symbol Clock Error

Proper analysis of a radio manufacturer’s modulator requires digital modulation analysis plots, such as Distribution, Eye Diagram, and Constellation. These plots provide visual diagnostics of issues, such as deviation and symbol clock errors, to catch failing radios before they are deployed. The 8800SX provides these plots as well as an exclusive “Cycle” feature, which allows ultra-fast toggling between the digital plots; ensuring full analysis in minimal time.

Cobham and TRX Systems are providing a new joint solution that integrates TRX’s NEON Signal Mapper Application with the 8800SX. NEON Signal Mapper automates the geo-referencing cloud storage, and 3D visualization of LMR test data for technicians who use Cobham test equipment to record and analyze two-way radio signals inside buildings and outdoors.  

The 8800SX is designed for complete automated radio test and alignment for analog and digital radios. Using the accurate instrumentation and high-speed remote command architecture, the 8800SX optimizes radio performance in minutes; with minimal user interaction. Available automated test and alignments are available for various radio manufacturers including:

o   Motorola

o   Harris

o   Kenwood

o   EF Johnson

o   Hytera

Multiple automated test and alignment options can be installed on the 8800SX. Operators are only required to know radio type, such as Motorola MOTOTRBO™, not radio model number. The unique “Read Radio” feature queries the radio to gather the specific model number, as well as supply the specific test and alignment parameters for that model number as determined by the manufacturers. Specific tests and alignments can be selected and configured. Pressing “Run” enables the program and executes the selected tests.
